====Windows和Ubuntu双系统==== | ====Windows和Ubuntu双系统==== | ||
很少的情况下,Windows和Ubuntu的双系统会有问题。一般的,windows操作系统应该先安装,因为它的引导程序很特别。一个windows安装通常占用整个硬盘,所以分区需要更改,为Ubuntu分区创建空间(在调整空间之前,你需要清除不需要的文件并整理碎片)。在windows vista里面要调整windows分区可以使用 管理工具 --> 磁盘管理工具 里面的调整分区选项。如果使用windows XP (或其他windows系统),使用 [[#GParted Partition Manager|GParted partition manager]] 调整windows分区,在硬盘上为ubuntu分区留下空间。如果按照如此方式调整,安装ubuntu作为第二操作系统不会有问题,并且ubuntu LiveCD会自动完成,允许ubuntu LiveCD使用“最大可用空间”方式安装。 | |||
一个windows分区需要至少20GB空间(推荐30GB),Ubuntu分区至少要10GB分区(推荐20GB)。很明显,如果你有足够的磁盘空间,可以为你喜欢的系统留尽量大的空间。要得到其他分区规划的情况,可以参考[http://www.psychocats.net/ubuntu/partitioning Psychocats Guide to Partitioning]。 | |||
替代方案有: | |||
*[http://www.wubi-installer.org/ Wubi](基于windows的Ubuntu安装程序),一个官方的双系统安装程序,允许ubuntu挂在windows环境下的一个虚拟磁盘里面(会造成稍许的性能降低)。因为安装需要一个完整的windows系统,所以仅仅建议为短时间评估的目的按这种方式安装。一个永久的Ubuntu安装应有自己文件系统的分区,就不会再依赖windows。 | |||
*[http://neosmart.net/dl.php?id=1 EasyBCD],是一个自由的windows程序允许你配置Vista引导程序 [http://neosmart.net/wiki/display/EBCD/Ubuntu dual-boot Windows Vista and Ubuntu](其他的操作系统也可以)。 | |||
====使用启动管理器改变GRUB设置==== | |||
GRUB是控制哪个操作系统会默认启动和其他启动设置的工具。你可以使用启动管理器改变GRUB设置: | |||
系统 -> 管理 -> 启动管理器 | |||
如果没有安装,就安装它: | |||
sudo apt-get install startupmanager | sudo apt-get install startupmanager | ||
:Note: | :Note: 你也可以在命令行界面下编辑GRUB设定 [[#GRUB_boot_manager_settings|manually]] 。 | ||
==== | ====Mac OS X 和 Ubuntu双系统==== | ||
Mac OS | Mac OS X与Linux有相似的结构(它基于BSD UNIX)。Mac OS X 和 Ubuntu双系统的教程可以在这里找到[https://help.ubuntu.com/community/MacBookPro1-1_1-2/Intrepid here]。 | ||
===== | ===== 后安装Mac OS X,先装Ubuntu===== | ||
* | *如果您决定和OS X双启动,在Ubuntu安装时选择ext2作为您的分区格式。(对此,Super Grub的CD盘是个有用的工具。您可以在 [http://supergrub.forjamari.linex.org forjamari.linex.org]下载Super Grub .iso镜像,并将镜像刻录到一张CD_ROM。) | ||
* | *一旦您已经安装了Ubuntu,修改Grub启动菜单: | ||
sudo nano /boot/grub/menu.lst | sudo nano /boot/grub/menu.lst | ||
: | :并添加下列几行: | ||
title Mac OS X | title Mac OS X | ||
root (hd0,0) | root (hd0,0) | ||
第99行: | 第97行: | ||
chainloader +1 | chainloader +1 | ||
重启您的Mac并在Mac OS X中进入终端(如果您有任何启动问题,从您的Mac OS X DVD启动)。按F8并输入-s。输入: | |||
fdisk -e /dev/rdisk0 | fdisk -e /dev/rdisk0 | ||
第107行: | 第105行: | ||
reboot | reboot | ||
* | *如果仍然不能确定它是否正确工作,使用Super Grub CD光盘并激活grub。 | ||
===== | =====在Mac OS X之后安装Ubuntu===== | ||
* | *如果您在启动时得到错误信息,例如引导时的HFS+error,您同样可以用Super Grub光盘来修复Linux GRUB和Winows MBR(启动记录管理)。 | ||
* | *一旦您安装了Ubuntu,修改Grub启动菜单: | ||
sudo nano /boot/grub/menu.lst | sudo nano /boot/grub/menu.lst | ||
: | :并添加下列几行: | ||
title Mac OS X | title Mac OS X | ||
root (hd0,0) | root (hd0,0) | ||
第121行: | 第119行: | ||
chainloader +1 | chainloader +1 | ||
: | :如果您在GRUB中遇到Mac OS X或Windows的问题,尝试修改Mac OS X的Grub条目。 | ||
:change root (hd0,0) to root (hd0,1) | :change root (hd0,0) to root (hd0,1) | ||
这意味着您将从第一分区启动。您可以尝试任何分区数字直到正确。 | |||
==== | ====将Intrepid升级到Jaunty==== | ||
如果您在使用一个旧版本的Ubuntu,您也许希望升级到Jaunty。为防止软件膨胀,建议一个新的安装。 | |||
* | *分布升级是可能的,使用[[#Synaptic Package Manager|新立得]],单击选择"完全升级选项。" | ||
* | *另外,使用update-manager (全部版本): | ||
sudo apt-get install update-manager | sudo apt-get install update-manager | ||
sudo update-manager -d | sudo update-manager -d | ||
* | *您也可以使用: | ||
sudo apt-get dist-upgrade | sudo apt-get dist-upgrade | ||
升级过程的截图可以在[http://www.ubuntugeek.com/how-to-upgrade-ubuntu-810-intrepid-to-ubuntu-904-jaunty.html UbuntuGeek upgrade guide]找到。 | |||
==== | ====全新安装后重新安装应用程序==== | ||
如果您通过全新安装升级您的Ubuntu系统,可以标记您旧系统上安装的包和服务(在升级前)并将设置(“标记”)保存到一个文件。然后安装Ubuntu新版本并允许系统使用“标记”文件存储的设置重新安装包和服务。指导参见[http://ubuntuforums.org/showthread.php?t=1057608 Ubuntu forum thread]。简而言之: | |||
* | *在旧系统上:新立得软件包管理器->文件->保存标记的项目。 | ||
* | *将标记文件保存到一个外部存储器,例如USB drive。 | ||
* | *在安装新系统前,完成您系统上其他重要文件的备份(例如/home目录)。 | ||
* | *在刚安装的新系统中,再次打开新立得软件包管理器->文件->读取标记的项目并载入之前保存在您的USB drive(或其他外部存储器)中的文件。 | ||
注意:许多软件包,依赖包以及兼容性随着Ubuntu的版本而改变,因此这种方法并不总是有效。[[#Upgrading Intrepid to Jaunty|自动升级]]仍然是推荐的方法。 | |||

== | == 添加额外的Ubuntu软件仓库 == | ||
软件包和程序可以在有标准结构的综合在线网站(即软件仓库)免费下载。有被Kubuntu/Ubuntu开发社区官方认可和监督软件仓库,同时也有其他的软件仓库是独立提供的,没有官方认可或管理(应当小心使用)。更多的信息可以在[https://help.ubuntu.com/community/Repositories/Ubuntu the Ubuntu Repository Guide]得到。 | |||
=== | === 软件库的类型 === | ||
* | *Ubuntu中有四种主要的软件库类型: | ||
:* main - | :* main - 由Canonical提供支持。这是发行版的主要部分。 | ||
:* restricted - | :* restricted - 没有以[http://en.wikipedia.org/wiki/GNU_General_Public_License GPL] (或相似软件许可)许可的软件,然而由Canonical提供支持。 | ||
:* universe - | :* universe - 以GPL(或相似许可)许可的软件并由用户提供支持。 | ||
:* multiverse - | :* multiverse - 没有以GPL(或相似许可)许可的软件,但是由用户提供支持。 | ||
* | *另外还有三种软件库类型: | ||
:* jaunty-updates - | :* jaunty-updates - 官方软件包的更新。 | ||
:* jaunty-backports - | :* jaunty-backports - 回迁至Jaunty Jackalope的Jaunty+1(Karmic)软件的当前版本。 | ||
:* jaunty-proposed - | :* jaunty-proposed - 计划的更新和修改(可能不稳定的最新版)。 | ||
==== | ====第三方软件库==== | ||
软件开发者经常维护他们自己的软件库,软件包可以从那里下载并直接安装到您的计算机上(如果您将软件库添加到源列表中)。很多这样的第三方软件库和软件包从未被(k)Ubuntu/Debian社区考察并且对您的计算机有一定风险。木马,后门和其他恶意的软件能够存在于任何未受管理的软件库。当使用没有(k)Ubuntu/Debian社区签名的软件库,确保您在激活软件库和安装软件包前对那个网站有完全的信心。 | |||
=== | ===用新立得软件包管理器添加软件库=== | ||
这是首选的方法。 | |||
* | *系统 -> 系统管理 -> 新立得软件包管理器 -> 设置 -> 软件库。 | ||
* | *这里您可以激活Ubuntu软件和第三方软件的软件库。 | ||
* | *对于第三方软件选择 添加 -> 输入软件库的地址。它有一个类似这样的格式: | ||
deb <nowiki>http://archive.ubuntu.com/ubuntu/</nowiki> jaunty main restricted | deb <nowiki>http://archive.ubuntu.com/ubuntu/</nowiki> jaunty main restricted | ||
deb-src <nowiki>http://archive.ubuntu.com/ubuntu/</nowiki> jaunty main restricted | deb-src <nowiki>http://archive.ubuntu.com/ubuntu/</nowiki> jaunty main restricted | ||
:*'' | :*''例如:'' 添加Medibuntu软件库,添加: | ||
deb <nowiki>http://packages.medibuntu.org/</nowiki> jaunty free non-free | deb <nowiki>http://packages.medibuntu.org/</nowiki> jaunty free non-free | ||
:* | :*下载软件库的key到一个文件夹。 | ||
:::*'' | :::*''例如:'' Medibuntu的key可以从这里下载 | ||
::::::<nowiki>http://packages.medibuntu.org/medibuntu-key.gpg</nowiki> | ::::::<nowiki>http://packages.medibuntu.org/medibuntu-key.gpg</nowiki> | ||
::* | ::* 然后从这里增加key: | ||
:: | ::系统 -> 系统管理 -> 新立得软件包管理器 -> 设置 -> 软件库 -> 身份验证 -> 导入密钥文件... | ||
:* | :*(或者,您可以从终端用命令行手动添加key。参考[[#Add Repository keys|Add Repository keys]].) | ||
* | *从新的软件库刷新软件包列表: | ||
:: | :: 新立得软件包管理器 -> 刷新 | ||
=== | ===手动添加软件库=== | ||
* | *请自担风险。仅在您明白自己在做什么时修改Ubuntu的默认sources.list。混用软件库可能'''破坏'''您的系统。更多信息参见[https://help.ubuntu.com/community/Repositories/CommandLine Ubuntu Command-line Repository guide]. | ||
:* | :* 建立您现在sources.list的备份。 | ||
sudo cp -p /etc/apt/sources.list /etc/apt/sources.list_backup | sudo cp -p /etc/apt/sources.list /etc/apt/sources.list_backup | ||
注意:: sudo - 以root权限运行命令。cp = 复制。-p = 如果文件已经存在提醒改写。 | |||
:* | :*修改sources.list: | ||
sudo nano /etc/apt/sources.list | sudo nano /etc/apt/sources.list | ||
:: | ::或者使用图形界面编辑器: | ||
gksudo gedit /etc/apt/sources.list | gksudo gedit /etc/apt/sources.list | ||
::* | ::*注意:要使用您的本地镜像您可以添加"''xx.''"到''archive.ubuntu.com''之前,其中<b>xx</b> = 您的国家代码。 | ||
:::::'' | :::::''例如:'' <nowiki>deb http://gb.archive.ubuntu.com/ubuntu jaunty main restricted universe multiverse</nowiki> indicates a repository for Great Britain (gb). | ||
:* | :*这里是一个sources.list的示例。在最后已经添加了Medibuntu和Google的软件库: | ||
<pre> | <pre> | ||
第305行: | 第303行: | ||
</pre> | </pre> | ||
:* | :*下载并添加软件库key(密钥)到您的密钥圈。参见[[#Add repository keys|Add repository keys]]。 | ||
:* | :*从新软件库刷新软件包列表: | ||
sudo apt-get update | sudo apt-get update | ||
=== | ===添加软件库key=== | ||
:* | :* 下载软件库的gpg keys并自动添加它们到您的软件库密钥圈: | ||
:::*'' | :::*''例如:'' 得到并添加Medibuntu软件库的key: | ||
wget --quiet <nowiki>http://packages.medibuntu.org/medibuntu-key.gpg</nowiki> -O - | sudo apt-key add - | wget --quiet <nowiki>http://packages.medibuntu.org/medibuntu-key.gpg</nowiki> -O - | sudo apt-key add - | ||
:::*'' | :::*''例如:'' 得到并添加Google软件库的key: | ||
wget --quiet <nowiki>https://dl-ssl.google.com/linux/linux_signing_key.pub</nowiki> -O - | sudo apt-key add - | wget --quiet <nowiki>https://dl-ssl.google.com/linux/linux_signing_key.pub</nowiki> -O - | sudo apt-key add - | ||
注意:wget - 从一个网络地址取回一个文件。--quiet = 没有输出。-O = 输出下载的项目到终端。这里 |(竖线标志)用来捕获前面命令的输出(在我们的例子中,是屏幕)并用它作为后面命令的输入(例如, apt-key,即添加到密钥圈)。 | |||

* | *阅读 [[#一般性声明|一般性声明]] | ||
* | *阅读 [[#添加额外的Ubuntu软件仓库|添加额外的Ubuntu软件仓库]] | ||
很多新用户将使用[[#新立得软件包管理器|新立得软件包管理器]]来安装软件包。这些指导对应于在终端通过命令行来安装软件包。可以这样启动终端: | |||
: | :应用程序 -> 附件 -> 终端 | ||
* | *安装软件包: | ||

::*'' | ::*''例如:'' | ||
apt-cache search Music MP3 | apt-cache search Music MP3 | ||
apt-cache search "Text Editor" | apt-cache search "Text Editor" | ||
* | *[[#添加额外的Ubuntu软件仓库|添加/删除软件库]]后更新apt软件包数据库: | ||
sudo apt-get update | sudo apt-get update | ||
* | *更新软件包: | ||
sudo apt-get upgrade | sudo apt-get upgrade | ||
* | *更新整个发行版(e.g. 从Intrepid到Jaunty): | ||
sudo apt-get dist-upgrade | sudo apt-get dist-upgrade | ||
==== | ====安装.deb软件包==== | ||
Debian (.deb) | Debian (.deb)软件包是Ubuntu中使用的软件包。您可以安装任何.deb软件包到您的系统。.deb文件一般只需点击它们,便可从您的文件管理器(Nautilus)中安装, 这是因为默认安装器和文件关联已经在Ubuntu中设置好了。这些说明是面向那些愿意从命令行终端(Terminal)安装软件包的人。 | ||
* | *安装一个下载的Debian(Ubuntu)软件包(.deb): | ||
sudo dpkg -i ''packagename''.deb | sudo dpkg -i ''packagename''.deb | ||
* | *删除一个Debian(Ubuntu)软件包(.deb): | ||
sudo dpkg -r ''packagename'' | sudo dpkg -r ''packagename'' | ||
* | *重新配置/修复一个安装的Debian(Ubuntu)软件包(.deb): | ||
sudo dpkg-reconfigure ''packagename'' | sudo dpkg-reconfigure ''packagename'' | ||
::''* | ::''*例如:'' | ||
sudo dpkg-reconfigure mpd | sudo dpkg-reconfigure mpd | ||
==== | ====处理(Tar/GZip)和(Tar/Bzip2)归档==== | ||
(Tar/GZip) | (Tar/GZip)归档以“.tar.gz”结尾ie,而(Tar/Bzip2)归档以“.tar.bz2”结尾。Bzip2是更新的,压缩效率更高的方法。这些文件一般可以通过点击它们自动提取文件,因为合适的归档应用程序及文件关联已在Ubuntu中默认设置。这个说明是面向那些愿意使用命令行终端的人。 | ||
:* | :*提取文件: | ||
tar xvf ''packagename''.tar.gz | tar xvf ''packagename''.tar.gz | ||
注意:tar是一个能从归档中提取文件的应用程序,必要时解压缩。 | |||
::-x | ::-x 意味提取。 | ||
::-v | ::-v 意味详尽(列出它正在提取什么)。 | ||
::-f | ::-f 明确使用的文件。 | ||
* | *解压缩“.gz”文件 | ||
gunzip ''file''.gz | gunzip ''file''.gz | ||
* | *解压缩“.bz2"文件 | ||
bunzip2 ''file''.bz2 | bunzip2 ''file''.bz2 | ||
:: | ::注意:您也可以通过下面方法解压缩一个包。先用命令gunzip(对.gz)或者bunzip2(对.bz2),得到.tar文件,然后用tar提取它。 | ||
:* | :*创建一个.gz归档: | ||
tar cvfz ''packagename''.tar.gz folder | tar cvfz ''packagename''.tar.gz folder | ||
:* | :*创建一个.bz2归档: | ||
tar cvfj ''packagename''.tar.bz2 folder | tar cvfj ''packagename''.tar.bz2 folder | ||
==== | ====从源文件安装软件包==== | ||
* | *确保您有需要的开发工具(例如,libraries, compilers, headers): | ||
sudo apt-get install build-essential | sudo apt-get install build-essential | ||
sudo apt-get install linux-headers-`uname -r` | sudo apt-get install linux-headers-`uname -r` | ||
:: | ::注意: "uname -r" 列出您现在使用的内核 | ||
* | *从包含源文件的归档中提取: | ||
tar xvf ''sourcefilesarchive''.tar.gz | tar xvf ''sourcefilesarchive''.tar.gz | ||
* | *使用软件包的脚本Build(在这里是配置脚本),编译软件包(make),然后安装编译的软件包到您的系统,(make install): | ||
cd ''/path/to/extracted/sourcefiles'' | cd ''/path/to/extracted/sourcefiles'' | ||
./configure | ./configure | ||
第418行: | 第416行: | ||
sudo make install | sudo make install | ||
:: | ::注意:在当前目录一个文件名之前输入./使Linux Shell尝试以一个应用程序运行文件,即使它不在路径(当您输入一个命令名时它搜索的一系列文件夹)中。如果您得到一个“permission denied”的错误,那个文件没有可执行权限。要修复它: | ||
sudo chmod +x ''filename'' | sudo chmod +x ''filename'' | ||
::'' | ::''例如:'' 在上面的说明中,configure是从源文件编译软件包的shell脚本。确保configure脚本是可执行的: | ||
sudo chmod +x configure | sudo chmod +x configure | ||
===== | =====从源文件中新建一个.deb软件包===== | ||
如果您从源文件编译成功,您可以制作一个Debian(Ubuntu)软件包(.deb)在将来使用: | |||
* | *安装软件包工具: | ||
sudo apt-get install checkinstall | sudo apt-get install checkinstall | ||
* | *使用“checkinstall”重新编译软件包: | ||
cd ''/path/to/extracted/package'' | cd ''/path/to/extracted/package'' | ||
第437行: | 第435行: | ||
sudo checkinstall | sudo checkinstall | ||
* | *保存得到的“.deb“文件在将来使用。它可以今后用下面方法安装: | ||
sudo dpkg -i ''packagename''.deb | sudo dpkg -i ''packagename''.deb | ||
注意:这些是基本的说明,可能并不总是可行。一些软件包需要指定额外的依赖和可选的参数以便成功编译它们。 | |||
=== Aptitude === | === Aptitude === | ||
Aptitude是一个可以取代apt-get的基于终端的软件包管理器。Aptitude标记自动安装和软件包并在没有程序依赖事删除它们。这使得完全删除应用程序变得简单。 | |||
使用,在命令中用aptitude代替apt-get。例如: | |||
sudo aptitude install ''packagename'' | sudo aptitude install ''packagename'' | ||
sudo aptitude remove ''packagename'' | sudo aptitude remove ''packagename'' | ||
sudo aptitude update | sudo aptitude update | ||
sudo aptitude upgrade | sudo aptitude upgrade | ||
对于一个基于ncurses的图形用户界面,输入 | |||
sudo aptitude | sudo aptitude | ||
更多信息参见[http://people.debian.org/~dburrows/aptitude-doc/en/ the aptitude documentation]。 | |||
=== | ===新立得软件包管理器=== | ||
虽然“apt-get”和“aptitude”是安装程序/软件包的快捷方法,您也可以使用新立得软件包管理器(系统 -> 系统管理 -> 新立得软件包管理器),一个安装程序/软件包的GUI方法。很多apt-get可用的(但不是全部)程序/软件包同样也存在于新立得软件包管理器中。这是许多桌面用户的首选方法。在这个指南中,当您看 | |||
sudo apt-get install ''package'' | sudo apt-get install ''package'' | ||
您可以简单得在新立得中搜索“package”并安装它。 | |||
* | * 系统 -> 系统管理 -> 新立得软件包管理器 | ||
* | * 搜索程序/软件包的名字。您也可以搜索它的描述中文字。 | ||
* | * 勾选选框“标记以便安装” | ||
* | * 单击“应用”按钮。 | ||
* | * 选择的程序和它的依赖将会被自动安装。 | ||
=== | ===添加/删除程序=== | ||
并非所有可以从apt-get,aptitude和新立得软件包管理器中得到的软件包都在添加/删除程序中。然而,这是对于Ubuntu新用户必不可少的界面,可以引导他们到首选的软件包。 | |||
* | * 应用程序 -> 添加/删除程序 | ||
* | * 搜索您想要添加的程序。例如:输入MP3得到一个mp3软件的列表。 | ||
* | * 勾选选框“标记以便安装” | ||
* | * 单击“应用”按钮 | ||
* | * 选择的程序将自动被安装。 | ||
=== | ===手动更新=== | ||

= | =Ubuntu附加应用程序= | ||
参见我们的[[Alternatives|全部附加应用程序列表]]. | |||
== | ==视觉效果应用程序== | ||
视觉效果应用程序指代图形用户界面的装饰。这些可以是附加图标,主题,壁纸,3-D效果等。 | |||
=== | ===Gnome视觉效果资源=== | ||
* [http://www.gnome-look.org Gnome Look] | * [http://www.gnome-look.org Gnome Look]有壁纸,过场动画,图标和用于窗口管理器(包括Metacity和Compiz)的主题及其他应用程序。 | ||
===Metacity=== | ===Metacity=== | ||
Metacity是Gnome桌面默认的复合窗口管理器。它是轻量级的,流线的且没有许多设置选项,但是在Gnome Look有许多可得到的主题。 | |||
===Compiz Fusion=== | ===Compiz Fusion=== | ||
Compiz | Compiz Fusion是一个独立的窗口管理器,允许高级的桌面效果例如旋转立方桌面。许多Ubuntu用户选择运行Compiz,它在Ubuntu中速度很快。安装: | ||
sudo apt-get install compiz compizconfig-settings-manager compiz-fusion-plugins-main compiz-fusion-plugins-extra emerald librsvg2-common | sudo apt-get install compiz compizconfig-settings-manager compiz-fusion-plugins-main compiz-fusion-plugins-extra emerald librsvg2-common | ||
要将Compiz作为窗口管理器: | |||
* | *选择Compiz设置: | ||
: | :系统 -> 首选项 -> CompizConfig Settings Manager | ||
: | :注意:您必须登出然后登入来使改动生效。 | ||
====Fusion Icon==== | ====Fusion Icon==== | ||
Fusion | Fusion Icon是一个托盘图标,允许您容易地在窗口管理器,窗口装饰之间装换,并且使您快速到达Compiz Settings Manager。这允许快速切换3-D桌面效果(或许对某些应用程序无法使用)。 | ||
sudo apt-get install fusion-icon | sudo apt-get install fusion-icon | ||
: | :应用程序 -> 系统工具 -> Compiz Fusion Icon | ||
您可以从图标容易地到达CompizConfig Settings Manager。 | |||
==== | ====旋转Compiz立方==== | ||
设置CompizConfig Settings Manager,激活“桌面立方体”和“旋转立方体”以及“视图切换”选项。点击每个的图标来定制设置。例如,改变立方体的外观,点击桌面立方体图标至它的设置。您可以在“视图切换”中为旋转立方体设置热键按钮。另外,按下Ctrl+Alt+鼠标左键并向您希望立方体旋转的方向拖拽鼠标(或者触摸板)。 | |||
记住,立方体在桌面之间旋转,如果桌面少于4个将无法构成立方体。您将无法得到一个立方体如果仅用2个桌面(您将得到一个“平面”)。当然,您仍然可以旋转平面的边缘,但这不是一个立方体。(刚从Windows OS来的用户可能没有多桌面概念的经验,但是它们很不错,一旦您学习如何使用)。 | |||
当运行Compiz fusion来作为窗口管理器,您必须在CompizConfig Settings Manger中改变桌面的默认数量。要激活4个桌面: | |||
:CompizConfig Settings Manager -> General -> General Options -> Desktop Size -> Horizontal Virtual Size -> 4 | :CompizConfig Settings Manager -> General -> General Options -> Desktop Size -> Horizontal Virtual Size -> 4 | ||
当您开始一个应用程序,您必须通过右击应用程序窗口的左上角并选择“至桌面...”选项,来将它安置在4个桌面中任一个。旋转立方体来展示不同的桌面。您也可以使用显示4个桌面的任务栏图标来到达桌面。 | |||

Ubuntu 9.04 (活泼的怀俄明野兔)
这份指南由Chua Wen Kiat (Kuala Lumpur, Malaysia)创建,现在由University of Latvia的Linux Center维护。
前言
关于Jaunty
- 于2009.4.23发布。
- 它的代号是活泼的怀俄明野兔,是Intrepid Ibex (8.10) (Intrepid+1)的后续版本。
- 活泼的怀俄明野兔不是LTS(长期支持)版。它的安全更新支持将持续到2010年10月。
如何获知你用的Ubuntu是哪个版本
打开命令行终端并输入:
lsb_release -a
如何获知Ubuntu核心的版本
uname -r
Ubuntu的新版本
- Ubuntu的发行周期是6个月,分别在4月和10月发布。
- Karmic Koala (9.10),计划在2009/10发布,也不是LTS版。
- (10.04 LTS),计划在2010.4发布,是下一个LTS(长期支持)版本。
Ubuntu的老版本
- Intrepid Ibex (8.10) (支持到2010.4)
- Hardy Heron (8.04 LTS) (桌面版本支持到2011.4,服务器版支持到2013.4)
- Gutsy Gibbon (7.10) (无长期支持)
- Feisty Fawn (7.04) (无长期支持)
- Dapper Drake (6.06 LTS) (桌面版本支持到2009.6,服务器版支持到2011.6)
一般性声明
- Ubuntu指南是非官方的,与Canonical公司没有任何关联。
- Ubuntu可以让用户使用图形界面或命令行界面完成工作。在Ubuntu里,命令行界面叫做终端,可以从 程序 -> 附件 -> 模拟终端 打开。Text inside the grey dotted box like this should be put into the command-line Terminal.
- 许多对操作系统的更改必须要有管理员权限。“sudo”可以暂时让一个用户拥有管理员权限(例如:安装程序或改变系统设置),例如:
sudo bash
- 当通过“运行程序”对话框打开一个图形应用程序的时候,应该用'gksudo'代替'sudo'。例如:
gksudo gedit /etc/apt/sources.list
- "man" 可以用来寻找一个命令的帮助手册。例如"man sudo"会显示"sudo"命令的帮助手册:
man sudo
- 尽管"apt-get"和"aptitude"是安装程序或软件包的快速方法,但是你仍然可以用Synaptic Package Manager,一个GUI的安装程序和软件包的方法。大多数(但并不是全部)程序或软件包可以用apt-get安装,也可以用新立得包管理器。在这份指南里,当你看到
sudo apt-get install package
你可以在新立得里面搜索package,并用这种方式安装。
- "程序"是在左下或左上的一个按钮,与微软的开始菜单类似。
- 如果你在用64位版本,请把"i386"用"amd64"代替。
安装Ubuntu
硬件需求
Ubuntu Jaunty Jackalope 在内存只有 384 Mb 的机器上仍然运行的很好. (安装至少需要256 Mb 内存, 而alternative的安装可以在内存只有192 Mb时运行.) 上网本可以运行Ubuntu Jaunty Jackalope.
安装需要3-4G硬盘空间,很舒服的运行需要8-10G硬盘。
如果你有一个更古老的机器,内存比这个少,可以考虑Xubuntu (如果内存在256MB和512MB之间) 或者PuppyLinux或者DSL (如果内存少于256MB)。
全新安装
从Ubuntu 9.04下载最新的版本。 参考this guide,以便从iso文件刻录光盘。 使用刻录好的光盘安装。
Windows和Ubuntu双系统
很少的情况下,Windows和Ubuntu的双系统会有问题。一般的,windows操作系统应该先安装,因为它的引导程序很特别。一个windows安装通常占用整个硬盘,所以分区需要更改,为Ubuntu分区创建空间(在调整空间之前,你需要清除不需要的文件并整理碎片)。在windows vista里面要调整windows分区可以使用 管理工具 --> 磁盘管理工具 里面的调整分区选项。如果使用windows XP (或其他windows系统),使用 GParted partition manager 调整windows分区,在硬盘上为ubuntu分区留下空间。如果按照如此方式调整,安装ubuntu作为第二操作系统不会有问题,并且ubuntu LiveCD会自动完成,允许ubuntu LiveCD使用“最大可用空间”方式安装。
一个windows分区需要至少20GB空间(推荐30GB),Ubuntu分区至少要10GB分区(推荐20GB)。很明显,如果你有足够的磁盘空间,可以为你喜欢的系统留尽量大的空间。要得到其他分区规划的情况,可以参考Psychocats Guide to Partitioning。
替代方案有:
- Wubi(基于windows的Ubuntu安装程序),一个官方的双系统安装程序,允许ubuntu挂在windows环境下的一个虚拟磁盘里面(会造成稍许的性能降低)。因为安装需要一个完整的windows系统,所以仅仅建议为短时间评估的目的按这种方式安装。一个永久的Ubuntu安装应有自己文件系统的分区,就不会再依赖windows。
- EasyBCD,是一个自由的windows程序允许你配置Vista引导程序 dual-boot Windows Vista and Ubuntu(其他的操作系统也可以)。
使用启动管理器改变GRUB设置
GRUB是控制哪个操作系统会默认启动和其他启动设置的工具。你可以使用启动管理器改变GRUB设置:
系统 -> 管理 -> 启动管理器
如果没有安装,就安装它:
sudo apt-get install startupmanager
- Note: 你也可以在命令行界面下编辑GRUB设定 manually 。
Mac OS X 和 Ubuntu双系统
Mac OS X与Linux有相似的结构(它基于BSD UNIX)。Mac OS X 和 Ubuntu双系统的教程可以在这里找到here。
后安装Mac OS X,先装Ubuntu
- 如果您决定和OS X双启动,在Ubuntu安装时选择ext2作为您的分区格式。(对此,Super Grub的CD盘是个有用的工具。您可以在 forjamari.linex.org下载Super Grub .iso镜像,并将镜像刻录到一张CD_ROM。)
- 一旦您已经安装了Ubuntu,修改Grub启动菜单:
sudo nano /boot/grub/menu.lst
- 并添加下列几行:
title Mac OS X root (hd0,0) makeactive chainloader +1
重启您的Mac并在Mac OS X中进入终端(如果您有任何启动问题,从您的Mac OS X DVD启动)。按F8并输入-s。输入:
fdisk -e /dev/rdisk0 flag 2 <--note that flag 2 is my Mac partition number two quit y reboot
- 如果仍然不能确定它是否正确工作,使用Super Grub CD光盘并激活grub。
在Mac OS X之后安装Ubuntu
- 如果您在启动时得到错误信息,例如引导时的HFS+error,您同样可以用Super Grub光盘来修复Linux GRUB和Winows MBR(启动记录管理)。
- 一旦您安装了Ubuntu,修改Grub启动菜单:
sudo nano /boot/grub/menu.lst
- 并添加下列几行:
title Mac OS X root (hd0,0) makeactive chainloader +1
- 如果您在GRUB中遇到Mac OS X或Windows的问题,尝试修改Mac OS X的Grub条目。
- change root (hd0,0) to root (hd0,1)
这意味着您将从第一分区启动。您可以尝试任何分区数字直到正确。
将Intrepid升级到Jaunty
如果您在使用一个旧版本的Ubuntu,您也许希望升级到Jaunty。为防止软件膨胀,建议一个新的安装。
- 分布升级是可能的,使用新立得,单击选择"完全升级选项。"
- 另外,使用update-manager (全部版本):
sudo apt-get install update-manager sudo update-manager -d
- 您也可以使用:
sudo apt-get dist-upgrade
升级过程的截图可以在UbuntuGeek upgrade guide找到。
全新安装后重新安装应用程序
如果您通过全新安装升级您的Ubuntu系统,可以标记您旧系统上安装的包和服务(在升级前)并将设置(“标记”)保存到一个文件。然后安装Ubuntu新版本并允许系统使用“标记”文件存储的设置重新安装包和服务。指导参见Ubuntu forum thread。简而言之:
- 在旧系统上:新立得软件包管理器->文件->保存标记的项目。
- 将标记文件保存到一个外部存储器,例如USB drive。
- 在安装新系统前,完成您系统上其他重要文件的备份(例如/home目录)。
- 在刚安装的新系统中,再次打开新立得软件包管理器->文件->读取标记的项目并载入之前保存在您的USB drive(或其他外部存储器)中的文件。
注意:许多软件包,依赖包以及兼容性随着Ubuntu的版本而改变,因此这种方法并不总是有效。自动升级仍然是推荐的方法。

添加额外的Ubuntu软件仓库
软件包和程序可以在有标准结构的综合在线网站(即软件仓库)免费下载。有被Kubuntu/Ubuntu开发社区官方认可和监督软件仓库,同时也有其他的软件仓库是独立提供的,没有官方认可或管理(应当小心使用)。更多的信息可以在the Ubuntu Repository Guide得到。
软件库的类型
- Ubuntu中有四种主要的软件库类型:
- main - 由Canonical提供支持。这是发行版的主要部分。
- restricted - 没有以GPL (或相似软件许可)许可的软件,然而由Canonical提供支持。
- universe - 以GPL(或相似许可)许可的软件并由用户提供支持。
- multiverse - 没有以GPL(或相似许可)许可的软件,但是由用户提供支持。
- 另外还有三种软件库类型:
- jaunty-updates - 官方软件包的更新。
- jaunty-backports - 回迁至Jaunty Jackalope的Jaunty+1(Karmic)软件的当前版本。
- jaunty-proposed - 计划的更新和修改(可能不稳定的最新版)。
第三方软件库
软件开发者经常维护他们自己的软件库,软件包可以从那里下载并直接安装到您的计算机上(如果您将软件库添加到源列表中)。很多这样的第三方软件库和软件包从未被(k)Ubuntu/Debian社区考察并且对您的计算机有一定风险。木马,后门和其他恶意的软件能够存在于任何未受管理的软件库。当使用没有(k)Ubuntu/Debian社区签名的软件库,确保您在激活软件库和安装软件包前对那个网站有完全的信心。
用新立得软件包管理器添加软件库
这是首选的方法。
- 系统 -> 系统管理 -> 新立得软件包管理器 -> 设置 -> 软件库。
- 这里您可以激活Ubuntu软件和第三方软件的软件库。
- 对于第三方软件选择 添加 -> 输入软件库的地址。它有一个类似这样的格式:
deb http://archive.ubuntu.com/ubuntu/ jaunty main restricted deb-src http://archive.ubuntu.com/ubuntu/ jaunty main restricted
- 例如: 添加Medibuntu软件库,添加:
deb http://packages.medibuntu.org/ jaunty free non-free
- 下载软件库的key到一个文件夹。
- 例如: Medibuntu的key可以从这里下载
- http://packages.medibuntu.org/medibuntu-key.gpg
- 然后从这里增加key:
- 系统 -> 系统管理 -> 新立得软件包管理器 -> 设置 -> 软件库 -> 身份验证 -> 导入密钥文件...
- (或者,您可以从终端用命令行手动添加key。参考Add Repository keys.)
- 从新的软件库刷新软件包列表:
- 新立得软件包管理器 -> 刷新
手动添加软件库
- 请自担风险。仅在您明白自己在做什么时修改Ubuntu的默认sources.list。混用软件库可能破坏您的系统。更多信息参见Ubuntu Command-line Repository guide.
- 建立您现在sources.list的备份。
sudo cp -p /etc/apt/sources.list /etc/apt/sources.list_backup
注意:: sudo - 以root权限运行命令。cp = 复制。-p = 如果文件已经存在提醒改写。
- 修改sources.list:
sudo nano /etc/apt/sources.list
- 或者使用图形界面编辑器:
gksudo gedit /etc/apt/sources.list
- 注意:要使用您的本地镜像您可以添加"xx."到archive.ubuntu.com之前,其中xx = 您的国家代码。
- 例如: deb http://gb.archive.ubuntu.com/ubuntu jaunty main restricted universe multiverse indicates a repository for Great Britain (gb).
- 这里是一个sources.list的示例。在最后已经添加了Medibuntu和Google的软件库:
#deb cdrom:[Ubuntu 8.10 _Jaunty Jackalope_ - Release i386 (20081029.1)]/ jaunty main restricted # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://gb.archive.ubuntu.com/ubuntu/ jaunty main restricted deb-src http://gb.archive.ubuntu.com/ubuntu/ jaunty main restricted ## Major bug fix updates produced after the final release of the ## distribution. deb http://gb.archive.ubuntu.com/ubuntu/ jaunty-updates main restricted deb-src http://gb.archive.ubuntu.com/ubuntu/ jaunty-updates main restricted ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.

- 下载并添加软件库key(密钥)到您的密钥圈。参见Add repository keys。
- 从新软件库刷新软件包列表:
sudo apt-get update
添加软件库key
- 下载软件库的gpg keys并自动添加它们到您的软件库密钥圈:
- 例如: 得到并添加Medibuntu软件库的key:
wget --quiet http://packages.medibuntu.org/medibuntu-key.gpg -O - | sudo apt-key add -
- 例如: 得到并添加Google软件库的key:
wget --quiet https://dl-ssl.google.com/linux/linux_signing_key.pub -O - | sudo apt-key add -
注意:wget - 从一个网络地址取回一个文件。--quiet = 没有输出。-O = 输出下载的项目到终端。这里 |(竖线标志)用来捕获前面命令的输出(在我们的例子中,是屏幕)并用它作为后面命令的输入(例如, apt-key,即添加到密钥圈)。
Ubuntu软件包安装和升级
Apt和软件包基础
- 阅读 一般性声明
- 阅读 添加额外的Ubuntu软件仓库
很多新用户将使用新立得软件包管理器来安装软件包。这些指导对应于在终端通过命令行来安装软件包。可以这样启动终端:
- 应用程序 -> 附件 -> 终端
- 安装软件包:
sudo apt-get install packagename
- 例如:
sudo apt-get install mpd sbackup
- 删除软件包:
sudo apt-get remove packagename
- 删除所有的依赖:
sudo apt-get autoremove
- 例如:
sudo apt-get remove mpd sbackup
- 搜索软件包:
apt-cache search <keywords>
- 例如:
apt-cache search Music MP3 apt-cache search "Text Editor"
- 添加/删除软件库后更新apt软件包数据库:
sudo apt-get update
- 更新软件包:
sudo apt-get upgrade
- 更新整个发行版(e.g. 从Intrepid到Jaunty):
sudo apt-get dist-upgrade
安装.deb软件包
Debian (.deb)软件包是Ubuntu中使用的软件包。您可以安装任何.deb软件包到您的系统。.deb文件一般只需点击它们,便可从您的文件管理器(Nautilus)中安装, 这是因为默认安装器和文件关联已经在Ubuntu中设置好了。这些说明是面向那些愿意从命令行终端(Terminal)安装软件包的人。
- 安装一个下载的Debian(Ubuntu)软件包(.deb):
sudo dpkg -i packagename.deb
- 删除一个Debian(Ubuntu)软件包(.deb):
sudo dpkg -r packagename
- 重新配置/修复一个安装的Debian(Ubuntu)软件包(.deb):
sudo dpkg-reconfigure packagename
- *例如:
sudo dpkg-reconfigure mpd
处理(Tar/GZip)和(Tar/Bzip2)归档
(Tar/GZip)归档以“.tar.gz”结尾ie,而(Tar/Bzip2)归档以“.tar.bz2”结尾。Bzip2是更新的,压缩效率更高的方法。这些文件一般可以通过点击它们自动提取文件,因为合适的归档应用程序及文件关联已在Ubuntu中默认设置。这个说明是面向那些愿意使用命令行终端的人。
- 提取文件:
tar xvf packagename.tar.gz
注意:tar是一个能从归档中提取文件的应用程序,必要时解压缩。
- -x 意味提取。
- -v 意味详尽(列出它正在提取什么)。
- -f 明确使用的文件。
- 解压缩“.gz”文件
gunzip file.gz
- 解压缩“.bz2"文件
bunzip2 file.bz2
- 注意:您也可以通过下面方法解压缩一个包。先用命令gunzip(对.gz)或者bunzip2(对.bz2),得到.tar文件,然后用tar提取它。
- 创建一个.gz归档:
tar cvfz packagename.tar.gz folder
- 创建一个.bz2归档:
tar cvfj packagename.tar.bz2 folder
从源文件安装软件包
- 确保您有需要的开发工具(例如,libraries, compilers, headers):
sudo apt-get install build-essential sudo apt-get install linux-headers-`uname -r`
- 注意: "uname -r" 列出您现在使用的内核
- 从包含源文件的归档中提取:
tar xvf sourcefilesarchive.tar.gz
- 使用软件包的脚本Build(在这里是配置脚本),编译软件包(make),然后安装编译的软件包到您的系统,(make install):
cd /path/to/extracted/sourcefiles ./configure sudo make sudo make install
- 注意:在当前目录一个文件名之前输入./使Linux Shell尝试以一个应用程序运行文件,即使它不在路径(当您输入一个命令名时它搜索的一系列文件夹)中。如果您得到一个“permission denied”的错误,那个文件没有可执行权限。要修复它:
sudo chmod +x filename
- 例如: 在上面的说明中,configure是从源文件编译软件包的shell脚本。确保configure脚本是可执行的:
sudo chmod +x configure
从源文件中新建一个.deb软件包
如果您从源文件编译成功,您可以制作一个Debian(Ubuntu)软件包(.deb)在将来使用:
- 安装软件包工具:
sudo apt-get install checkinstall
- 使用“checkinstall”重新编译软件包:
cd /path/to/extracted/package ./configure sudo make sudo checkinstall
- 保存得到的“.deb“文件在将来使用。它可以今后用下面方法安装:
sudo dpkg -i packagename.deb
注意:这些是基本的说明,可能并不总是可行。一些软件包需要指定额外的依赖和可选的参数以便成功编译它们。
Aptitude
Aptitude是一个可以取代apt-get的基于终端的软件包管理器。Aptitude标记自动安装和软件包并在没有程序依赖事删除它们。这使得完全删除应用程序变得简单。 使用,在命令中用aptitude代替apt-get。例如:
sudo aptitude install packagename sudo aptitude remove packagename sudo aptitude update sudo aptitude upgrade
对于一个基于ncurses的图形用户界面,输入
sudo aptitude
更多信息参见the aptitude documentation。
新立得软件包管理器
虽然“apt-get”和“aptitude”是安装程序/软件包的快捷方法,您也可以使用新立得软件包管理器(系统 -> 系统管理 -> 新立得软件包管理器),一个安装程序/软件包的GUI方法。很多apt-get可用的(但不是全部)程序/软件包同样也存在于新立得软件包管理器中。这是许多桌面用户的首选方法。在这个指南中,当您看
sudo apt-get install package
您可以简单得在新立得中搜索“package”并安装它。
- 系统 -> 系统管理 -> 新立得软件包管理器
- 搜索程序/软件包的名字。您也可以搜索它的描述中文字。
- 勾选选框“标记以便安装”
- 单击“应用”按钮。
- 选择的程序和它的依赖将会被自动安装。
添加/删除程序
并非所有可以从apt-get,aptitude和新立得软件包管理器中得到的软件包都在添加/删除程序中。然而,这是对于Ubuntu新用户必不可少的界面,可以引导他们到首选的软件包。
- 应用程序 -> 添加/删除程序
- 搜索您想要添加的程序。例如:输入MP3得到一个mp3软件的列表。
- 勾选选框“标记以便安装”
- 单击“应用”按钮
- 选择的程序将自动被安装。
手动更新
- 阅读 一般性声明
- 阅读 添加额外的Ubuntu软件仓库
- 从终端(命令行界面)手动更新:
sudo apt-get update sudo apt-get upgrade
- 或者
- 使用新立得软件包管理器:
- 系统 -> 系统管理 -> 新立得软件包管理器 -> “刷新”然后“标记全部软件包以便升级”
- 如果有可以升级的软件包,您将被提示是否安装它们。
自动更新
- 使用新立得软件包管理器:
- 系统 -> 系统管理 -> 新立得软件包管理器 -> 设置 -> 首选项 -> 常规信息 -> 重新载入过时的软件包信息 -> 自动
Ubuntu附加应用程序
参见我们的全部附加应用程序列表.
视觉效果应用程序
视觉效果应用程序指代图形用户界面的装饰。这些可以是附加图标,主题,壁纸,3-D效果等。
Gnome视觉效果资源
- Gnome Look有壁纸,过场动画,图标和用于窗口管理器(包括Metacity和Compiz)的主题及其他应用程序。
Metacity
Metacity是Gnome桌面默认的复合窗口管理器。它是轻量级的,流线的且没有许多设置选项,但是在Gnome Look有许多可得到的主题。
Compiz Fusion
Compiz Fusion是一个独立的窗口管理器,允许高级的桌面效果例如旋转立方桌面。许多Ubuntu用户选择运行Compiz,它在Ubuntu中速度很快。安装:
sudo apt-get install compiz compizconfig-settings-manager compiz-fusion-plugins-main compiz-fusion-plugins-extra emerald librsvg2-common
要将Compiz作为窗口管理器:
- 选择Compiz设置:
- 系统 -> 首选项 -> CompizConfig Settings Manager
- 注意:您必须登出然后登入来使改动生效。
Fusion Icon
Fusion Icon是一个托盘图标,允许您容易地在窗口管理器,窗口装饰之间装换,并且使您快速到达Compiz Settings Manager。这允许快速切换3-D桌面效果(或许对某些应用程序无法使用)。
sudo apt-get install fusion-icon
- 应用程序 -> 系统工具 -> Compiz Fusion Icon
您可以从图标容易地到达CompizConfig Settings Manager。
旋转Compiz立方
设置CompizConfig Settings Manager,激活“桌面立方体”和“旋转立方体”以及“视图切换”选项。点击每个的图标来定制设置。例如,改变立方体的外观,点击桌面立方体图标至它的设置。您可以在“视图切换”中为旋转立方体设置热键按钮。另外,按下Ctrl+Alt+鼠标左键并向您希望立方体旋转的方向拖拽鼠标(或者触摸板)。
记住,立方体在桌面之间旋转,如果桌面少于4个将无法构成立方体。您将无法得到一个立方体如果仅用2个桌面(您将得到一个“平面”)。当然,您仍然可以旋转平面的边缘,但这不是一个立方体。(刚从Windows OS来的用户可能没有多桌面概念的经验,但是它们很不错,一旦您学习如何使用)。
当运行Compiz fusion来作为窗口管理器,您必须在CompizConfig Settings Manger中改变桌面的默认数量。要激活4个桌面:
- CompizConfig Settings Manager -> General -> General Options -> Desktop Size -> Horizontal Virtual Size -> 4
当您开始一个应用程序,您必须通过右击应用程序窗口的左上角并选择“至桌面...”选项,来将它安置在4个桌面中任一个。旋转立方体来展示不同的桌面。您也可以使用显示4个桌面的任务栏图标来到达桌面。
Emerald
Emerald是Compiz Fusion的主题引擎,有许多可得到的主题。(这些主题在与Compiz合并形成Compiz Fusion前,源自Beryl项目)用于Compiz Fusion的Emerald主题管理器可以这样安装:
sudo apt-get install emerald
Ubuntu壁纸
- 下载免费的Earthenibex壁纸。
修改USplash启动画面
这是您在启动被要求登陆并输入密码时看到的启动画面。您可以使用启动管理器(如果您在计算机上使用多系统,启动管理器也可以用于该变GRUB启动设置)改变USplash画面。安装:
sudo apt-get install startupmanager
- 开始:
系统 -> 系统管理 -> 启动管理器
您也可以使用一个不同的启动画面管理器,Splashy,代替USplash。安装:
sudo apt-get install splashy splashy-themes
Google桌面
Google Desktop for Linux是一个私有的widgets和应用程序套件,来使Google控制您的计算机从而允许您使用Google的服务。一个.deb包可以从Google Linux Downloads下载并安装。如要安装说明,参见Google Desktop for Linux Instructions.
Dock应用程序
Avant Window Manager,Cairo Dock,以及Wbar都是Ubuntu Linux上的类DOCK应用程序。一个dock将运行的应用程序作为图标展示在屏幕底部(就像Mac OS X桌面那样),取代工具栏面板元素(就像Windows和其他Linux窗口管理器那样)。参见这个[1]。
- Avant Window Navigator需要一个已安装并运行的桌面复合管理器(例如Metacity,Compiz,Xcompmgr,KDE4(Kubuntu),或者xfwm4(Xubuntu))。
- 安装并升级私有的nVidia或者ATI图形驱动以便复合管理器正常工作。
- 安装AWN:
sudo apt-get install avant-window-navigator awn-manager
- (注意:如果您使用Gnome(Ubuntu)并且没有安装复合管理器(例如Compiz),Metacity将作为一个组件被安装。)
- 激活AWN自启动:
- 菜单 -> 系统 -> 首选项 -> 会话 -> 添加...
avant-window-navigator
- 选择默认从dock菜单运行的applets:
- 菜单 -> 应用程序 -> 附件-> Avant Window Navigator Manager
- 您可以拖拽应用程序图标到列表上,然后从列表激活或者解除applets。
Cairo Dock
Cairo Dock可以和桌面复合管理器(例如Gnome的Metacity,Compiz,或者KDE4窗口管理器)一起使用或是单独使用。参见the Ubuntu installation instructions获取详细信息。它可以从软件源得到:
sudo apt-get install cairo-dock cairo-dock-plugins
wbar
wbar是一个快速启动栏(不是dock),拥有和Avant Window Manager和Cairo Dock相似的界面。它是基于GTK(Gnome)但可以在所有桌面环境中工作。它不需要安装复合管理器,因此更快并且更适合低端硬件系统。 它是Google gOS的默认配置,你可以从Google上直接获得它的.deb包。下载并安装(终端模式):
wget http://wbar.googlecode.com/files/wbar_1.3.3_i386.deb sudo dpkg -i wbar_1.3.3_i386.deb
- 自定义运行参数运行 wbar (例如 按下alt+F2)。例子:
wbar -isize 48 -j 1 -p bottom -balfa 40 -bpress -nanim 3 -z 2.5 -above-desk
- 另一个例子:
wbar -above-desk -pos bottom -isize 60 -nanim 1 -bpress -jumpf 0.0 -zoomf 1.5
想获得完整的启动选项,请查看:
wbar --help
Tip: If you want the "wave" effect just increase the -nanim value. I like the icons to just pop up so I don't use it, but with 9 icons 5 there is a nice "wave" effect.
Obviously, you could create a menu item with the command line options (similar to the examples above), or a batch file that can be automatically started at system startup (as a cron event or startup session).
You can also change wbar startup options by editing the configuration file:
sudo gedit /usr/share/wbar/dot.wbar
See this example configuration file. However, not all options are able to be set from the configuration file and must be run from the command line. For more info see this wbar guide.
wbarconf
wbar configuration utility 会以一个 .deb 包格式被下载并安装:
wget http://koti.kapsi.fi/~ighea/wbarconf/wbarconf_0.7.2-1_i386.deb sudo dpkg -i wbarconf_0.7.2-1_i386.deb
虚拟化
Virtualization allows a second operating system (OS), such as Windows or OS X, to be run from within Ubuntu. This requires extra RAM (because both Ubuntu and the virtualized second OS require separate amounts of RAM) and a license for the second OS. If you wish to run a virtualized instance of Windows XP, for instance, you must have a license for Windows XP.
VirtualBox
VirtualBox is a fast and complete virtualization solution owned and maintained by Sun Microsystems. There is a free and fully open-source edition available under the GNU GPL license.
- Install the open-source edition:
sudo apt-get install virtualbox-ose virtualbox-ose-source
- Start VirtualBox:
- VirtualBox OSE PC virtualization solution
For usage instructions, see the End-user documentation.
Xen
Xen is an efficient open-source virtualization ("hypervisor") platform which includes a recent merge with QEMU. It is free open source under a GPL license. Installation for the desktop must be from source (see the website for details). A commercial version is offered by Citrix.
A Xen virtual machine host can also be installed automatically with certain 64-bit CPUs, using the 64-bit Ubuntu Server LiveCD. (An Ubuntu desktop can then later be added -- see Ubuntu server).
VMWare
VMWare is a commercial virtualization platform that currently offers a free license (renewable yearly) for use with its server software. Installation instructions are on the website.
Keyboard errors in VMware guest
After installing VMWare 6.5, and installing a guest OS, the Function, arrow and Del/End/etc keys do not function. This is a bug with VMWare麓s code. Add this line to ~/.vmware/config (create file if necessary) to fix this issue:
xkeymap.nokeycodeMap = true
Crossover for Linux
Codeweavers' Crossover Office for Linux is a subscription-based commercial package that allows many Windows programs to be run on Ubuntu without the need for a Microsoft OS license or a complete virtualization system. See the website for more info. Codeweavers releases older versions of this product as the free package Wine.
Wine
Wine is a free open-source package that essentially consists of an older and more limited implementation of CrossOver for Linux. It is provided by Codeweavers. Like CrossOver for Linux, no Microsoft license or virtualization platform is required to run Windows programs.
sudo apt-get install wine
Also consider installing Microsoft's TrueType fonts:
sudo apt-get install msttcorefonts
IE6
Internet Explorer 6 可以在Wine下安装, albeit imperfectly. For most purposes, Firefox can be used (with the User Agent Switcher plugin) to mimic Internet Explorer, but for those instances when it can't, IE6 may be useful. A beta implementation of Internet Explorer 7 is also available from this package. For more info, see IEs 4 Linux.
- Make sure you have wine and cabextract packages:
sudo apt-get install wine cabextract
- Download IEs 4 Linux and install:
wget http://www.tatanka.com.br/ies4linux/downloads/ies4linux-latest.tar.gz tar zxvf ies4linux-latest.tar.gz cd ies4linux-* ./ies4linux --no-gui
Transgaming Cedega
Cedega is a commercial application (similar to CrossOver Office and Wine), for installing and running some Windows applications, specifically games, without the need for virtualization or a Microsoft license. It provides 3D support, software acceleration support, and a high level of DirectX support. Installation instructions are found on the website.
Mono
Mono is a free open source project sponsored by Novell to allow .NET programs to function in Linux (Ubuntu) and Mac OS X. The most recent version is available here.
sudo apt-get install mono-2.0-devel
Moonlight
Moonlight is part of the Novell Mono project that is an open source implementation of Silverlight (the Microsoft multimedia presentation platform). It is based on FFMpeg. It is made to work best with the Firefox 3 web browser, as a plugin. It is available here.
Netflix under Moonlight
Netflix streaming requires Silverlight 2.0. The current version of Moonlight is 1.0 (corresponding to Silverlight 1.0). Moonlight 2.0 is anticipated for mid-year 2009. Until this project is complete, or until Netflix agrees to stream video using Flashplayer, there are currently no methods for streaming Netflix in Linux.
教育娱乐应用
只要单击一下,就可以安装许多许多很好的应用。
- Applications -> Add/Remove Software -> Edutainment.
Below are a few examples that can be installed from this menu:
- Stellarium -- an astounding planetarium for the desktop
- K3DSurf -- a program for modeling 3,4,5, and 6 dimensional models.

谷歌地球
Google Earth gives you an annotated eagle's eye view of our planet. This is a free proprietary package (you must accept the license to use this package).
sudo apt-get install googleearth-package make-googleearth-package --force
- Doubleclick on the resulting .deb file.
- -- or --
To install the latest Linux binary, download and save the GoogleEarthLinux.bin package from Google Earth downloads. Then install:
chmod +x GoogleEarthLinux.bin ./GoogleEarthLinux.bin
Run:
- Applications -> Internet -> Google Earth 3D planet viewer
You should turn off the Google Earth -> View -> Atmosphere setting, or you might see clouds everywhere and the ground won't show up.
疑难解答
如果在打开谷歌地球时, 出现飞溅屏幕, 接着崩溃, you鈥檙e probably experiencing a common issue. Running ~/google-earth/googleearth in a terminal will show this error: ./googleearth-bin: relocation error: /usr/lib/i686/cmov/libssl.so.0.9.8: symbol BIO_test_flags, version OPENSSL_0.9.8 not defined in file libcrypto.so.0.9.8 with link time reference
To fix this, browse to the folder you installed Google Earth into. By default this will be google-earth in your home folder. Find the file libcrypto.so.0.9.8 and rename it to something else, like libcrypto.so.0.9.8.bak. Google Earth should now start correctly.
cd ~/google-earth sudo mv libcrypto.so.0.9.8 libcrypto.so.0.9.8.bak sudo ln -s /usr/lib/libcrypto.so.0.9.8 ~/google-earth/libcrypto.so.0.9.8
- (小贴士:你也可以用/home/用户名/google-earth 替代 ~/google-earth ).
For other issues, see the Ubuntu help pages on Google Earth.
卸载谷歌地球
运行/home/user/google-earth 目录下 (或者你安装谷歌地球的目录)的“uninstall”shell脚本来卸载.
专有应用
专有软件可以使你的互联网体验实现最大化, but is not open source. The software available includes Multimedia Codecs, Java Runtime Environment, and plug-ins for Firefox.
Restricted Extras
The Ubuntu Restricted Extras will install Adobe Flash Player, Java Runtime Environment (JRE) (sun-java-jre) with Firefox plug-ins (icedtea), a set of Microsoft Fonts (msttcorefonts), multimedia codecs (w32codecs or w64codecs), mp3-compatible encoding (lame), FFMpeg, extra Gstreamer codecs, the package for DVD decoding (libdvdread4, but see below for info on libdvdcss2), and the unrar archiver. This is a single command approach.
sudo apt-get install ubuntu-restricted-extras
Games Applications
There are some phenomenal games for Ubuntu Linux.
There are hundreds of free, open-source games available in Ubuntu. Most (including the KDE Games collection and the Gnome Games collection) can be accessed:
- Applications -> Add/Remove Software -> Games
Examples are:
- KMahjongg -- the solitaire Mahjongg tile-matching game.
- PouetChess -- an excellent 3-D chess game.
- PokerTH -- a very nice Texas Hold 'Em Poker
- Planet Penguin Racer -- Penguin slides down a 3-D luge run, catching fish. (Extreme Tux Racer is a newer version, but works in 32-bit only.)

PlaneShift
PlaneShift is a promising free full-immersion online fantasy game (MMPORG). Client downloads and patches are available here.
- Make the downloaded binary installation file executable:
cd /directory_where_downloaded chmod +x PlaneShift-v.0.42-x64.bin
- Run the executable binary as root (this must be done from the command line Terminal):
sudo ./PlaneShift-v.0.42-x64.bin
- Follow the instructions for installation. When prompted whether to manually set permissions, answer "no."
- During installation, most users have recommended installing this game to your /home directory as a single user installation, instead of to /opt for all users. This avoids permissions problems. I was able to install to /opt, but it takes some effort.
- Make sure your user belongs to the games group:
- System -> User Manager -> user -> Groups -> check games
- Download the updater patch psupdaterlinux64.zip and unzip it to your download directory.
- Run the updater as root:
chmod +x psupdater chmod +x psupdater.bin sudo ./psupdater
- Register for a free account at PlaneShift Registration.
- If you installed the game to the menu, it will be in
- Applications -> Lost & Found -> Client and Setup
To run it from the menu, I had to edit the menu entries by checking the box: "Run in terminal." Alternatively, run it from the command-line Terminal:
sudo /opt/PlaneShift/pssetup sudo /opt/PlaneShift/psclient
Notes: This game ran very slowly for me on a 32-bit installation with a DSL connection and I gave up. The 64-bit installation worked better, but there were still many freezes. This is a game very much in development, and is still in alpha stage.
PrBoom - the classic Doom2 game
PrBoom is a free open source port of the original first person shooter action game, Doom.
sudo apt-get install prboom freedoom timidity timidity-interfaces-extra
There are thousands of extra maps (Wads) available for this game. It is easiest to keep a directory for your wads in your home directory:
mkdir /home/user/wads
Place your doom2.wad, tnt.wad, or plutonia.wad (from your original game) into this folder. If you don't have one, you can copy the Freedom version of doom2.wad from /usr/share/games/freedoom into this folder. Place any new .wad's you have downloaded from the Internet into this folder as well. Then run the game using both the original iwad map as well as your new .wad map (you will only see the new map).
prboom -iwad /home/user/wads/doom2.wad -file /home/user/wads/new_wad.wad
Note: Only doom2.wad, tnt.wad, or plutonia.wad can be used as an iwad. You must have one of these in addition to any new wad you wish to use. When in doubt, use doom2.wad.
- Note: this game can also be installed using Applications -> Add/Remove Software -> Games as Freedoom, but you must also install timidity and timidity-interfaces-extra.

Multimedia Applications
Multimedia applications include music and video playback, CD and DVD playback and recording, and Internet TV as well as "terrestrial" (i.e. broadcast, satellite, and cable) TV viewing on your computer. Here is a nice review of some of the applications that enables conversion and handling of these types of files.
CDs and DVDs
DVD Playback Capability
To play encrypted DVDs, the libdvdcss2 package is essential. libdvdcss2 is a simple library designed for accessing DVDs like a block device without having to bother about the decryption. More information about this package can be found at VideoLAN.
- You can install libdvdcss2 as a 64-bit .deb package without installing the Medibuntu repositories:
wget -c http://packages.medibuntu.org/pool/free/libd/libdvdcss/libdvdcss2_1.2.10-0.2medibuntu1_amd64.deb sudo dpkg -i libdvdcss2_1.2.10-0.2medibuntu1_amd64.deb
- or a 32-bit .deb package:
wget -c http://packages.medibuntu.org/pool/free/libd/libdvdcss/libdvdcss2_1.2.10-0.2medibuntu1_i386.deb sudo dpkg -i libdvdcss2_1.2.10-0.2medibuntu1_i386.deb
- You can also use guidelines provided at Medibuntu. This will install the Medibuntu repositories on your system and then install the libdvdcss2 package:
sudo wget http://www.medibuntu.org/sources.list.d/jaunty.list --output-document=/etc/apt/sources.list.d/medibuntu.list sudo apt-get update sudo apt-get install medibuntu-keyring sudo apt-get update sudo apt-get install libdvdcss2
- You can also install 32 bit or 64 bit Windows multimedia codecs (if you haven't already done so using ubuntu-restricted-extras):
sudo apt-get install w32codecs
- or
sudo apt-get install w64codecs
- Instead of downloading directly from Medibuntu, you could also use the script included with the libdvdread4 package to download and install libdvdcss2:
sudo apt-get install libdvdread4 sudo /usr/share/doc/libdvdread4/install-css.sh
K9copy DVD-Ripper
K9copy is the free open source DVD backup, copying, compression, and authoring utility that requires libdvdcss. For other info, see this or this guide. You can also easily create MPEG-4 videos with this utility.
sudo apt-get install k9copy
dvd::rip
dvd::rip is a DVD backup/copy program, written in GTK-based perl, that uses the transcode video/audio processing and conversion tools. See the website for installation and official documentation. For other info, see this dvd::rip tutorial.
DVD Fab DVD Ripper
DVD Fab is the favoured DVD backup tool for today's DVD encryption methods. It must be run in Wine (since it is a Windows application). It comes as a fully featured 30-day trial, but see these instructions for fine-tuning the trial period.
Handbrake
Handbrake is a GPL-licenced open source tool for converting DVD to MPEG-4 (iPod format) that is an alternative to k9copy. A self-installing .deb file is available from the website for download.
FFMPEG video / audio conversion
FFMPEG is the swiss-army knife of video and audio format conversion. It succeeds when no other program can. It is free and open source. If it not yet installed on your system as part of another package (it is used by many video/audio editors), then install it:
sudo apt-get install ffmpeg
- To convert many different formats, read the FFMPEG documentation. Also see this tutorial.
Example: To convert a saved Flash video (.flv) to an MPEG-2 format playable on a DVD, convert:
ffmpeg -i samplevideo.flv -target ntsc-dvd samplevideo.mpg
Then use K3b (or Gnomebaker) to write the mpg file to a New DVD Data Project.
- For PAL use -target pal-dvd. For widescreen, use -target film-dvd. For other conversion tips, see this forum. (Note: Most Flash video has very low resolution, with a screen size of 360x270, for example. You may see a slight diminishment in resolution if you wish to convert it to 720x480 (which is the NTSC standard size) or other screen size. You can keep the original screen size and resolution by omitting the -target parameter.) If your original file is 16:9 widescreen and you desire a 4:3 letterbox output for playing on an overscanned TV, you may need to pad the file so that the widescreen is not compressed (see this forum):
ffmpeg -i samplevideo.flv -target ntsc-dvd -s 648x364 -padleft 36 -padright 36 -padtop 58 -padbottom 58 samplevideo.mpg
- You can also use the WinFF GUI and add the command (as above) as a "Preset," for subsequent use. For example:
- Video converter (WinFF) -> Edit -> Presets ->
- Preset Name: Letterbox -> Preset Label: 16:9 Widescreen to 4:3 Letterbox
- Preset command: -target ntsc-dvd -s 648x364 -padleft 36 -padright 36 -padtop 58 -padbottom 58
- Ouput file extension: mpg -> Category: DVD
- -> Add/Update -> Save
- To convert to MPEG-4 (mp4) files, use
ffmpeg -i samplevideo.flv outputvideo.mp4
FFMPEG GUI
WinFF is a free, GPL-licensed open source GUI frontend for FFMPEG. Install:
sudo apt-get install winff
- Run:
- Applications -> Multimedia -> Video converter (WinFF)
Join video segments
Individual video segments (MPEG-2, for example) can easily be joined:
cat samplevideo1.mpg samplevideo2.mpg samplevideo3.mpg > samplevideo123.mpg
- You can then write the resulting MPEG-2 file to a DVD and play it in most DVD players.
Save any streaming Flash video
An easy way is to install the Video Download Helper plug-in for Firefox.
Otherwise, most Flash videos download to the /tmp directory while you watch the video, creating a randomly-named video file there (such as Flashuh4G6s). When you close the webpage, this file in the /tmp directory will be erased. After the entire video has downloaded, but before you close the webpage, copy that file (such as Flashuh4G6s) to your home directory (where it will not be erased). Of course, for this to work, you must change your Flash (or Gnash) settings to allow an unlimited buffer. While watching your Flash video, right click to bring up the Flash -> Settings window. Set the Buffer to "Unlimited."
Once you have copied the file, rename it appropriately with the .flv added to the filename. You can then watch it using VLC or Mplayer.
Here is another method that involves making a symbolic link.
Convert Flash video audio to mp3
Once you have downloaded flash video content (.flv) from the Internet (using the Video Download Helper plug-in for Firefox, for example), the audio component can be converted to an mp3 using this command (from the command line Terminal). (This will work for any type of video file, not just Flash.)
ffmpeg -i nameofvideoclip.flv -ab 160k -ac 2 -ar 44100 -vn nameoffile.mp3
where -i indicates the input, -ab indicates the bit rate (in this example 160kb/sec), -vn means no video ouput, -ac 2 means 2 channels, -ar 44100 indicates the sampling frequency. See FFMPEG docs for more info.
DVD Author
DVD author allows you to create menus and format your MPEG-2 videos onto a DVD disc so that you can play it in a commercial DVD player. DVD Author is a command line tool, but several GUI's exist. Install:
sudo apt-get install dvdauthor
QDVDAuthor

Kolab
Kolab is the most comprehensive open-source groupware solution available and is distributed as a multi-platform solution. (It integrates easily with both Ubuntu (including Evolution) and KDE/Kubuntu (including Kontact).) It is free and open source with a GPL license (unlike other groupware solutions), yet enterprise support is also available. It is scalable to large organizations and is Outlook (MS-Exchange) and Mozilla compatible. This is a German package, however, and documentation in English is limited, which can make installation challenging. The Kolab website provides its own instructions for installation from source (currently v. 2.2). In brief:
- Install the compiler and other necessary stuff:
sudo apt-get install build-essential
- Make a directory for the Kolab installation and make it universally accessible:
sudo cd / sudo mkdir /kolab sudo chmod 777 /kolab
- Optional: If you wish to mount kolab in its own partition, then create a new partition (using Gparted, for example). Figure out the device name of your extra partition:
fdisk -l
- It should be something like /dev/sda3.
- Mount /dev/sda3 (or whatever your partition is) as /kolab by editing /etc/fstab:
sudo nano /etc/fstab
- and adding the line:
/dev/sda3 /kolab ext3 defaults,rw 0 0
- then reboot and make sure there are no errors.
- Make a directory into which to download kolab:
mkdir /kolabtmp
- Download all the current Kolab files:
cd /kolabtmp wget -r -l1 -nd --no-parent http://ftp.gwdg.de/pub/linux/kolab/server/beta/kolab-server-2.2.1-beta-1/ix86-debian4.0
- Install Kolab (as root using sudo -s):
sudo -s sh install-kolab.sh 2>&1 | tee kolab-install.log
- Reboot your system.
- Stop Kolab services and run the configuration utility:
sudo /kolab/bin/openpkg rc all stop sudo /kolab/sbin/kolab_bootstrap -b
- Obviously, you should know all your details, such as your fully qualified host name, domain details, etc., before doing this step. If you are not familiar with OpenLDAPand LDAP basics, you should learn about it, as Kolab uses the slapd OpenLDAP server daemon.
- Restart all Kolab services:
sudo /kolab/bin/openpkg rc all start
- Login to the web administrator interface using "manager" and the password you set at bootstrap configuration:
https://yourhost.yourdomain.name/admin
Kolab Debian package
- There is an Ubuntu/Kubuntu/Debian package for Kolab (v. 2.1), but no support for it exists. In fact, it is due to be removed from the Debian packages because of this lack of support. The installation instructions are included below for reference, and if you have success installing from the package, please add the steps you took to make it work.
sudo apt-get install kolabd kolab-webadmin
To reconfigure setup after the original installation, stop all web services:
sudo /etc/init.d/apache2 stop sudo /etc/init.d/kolabd stop sudo /etc/init.d/kolab-cyrus stop sudo /etc/init.d/postfix stop sudo /etc/init.d/saslauthd stop sudo /etc/init.d/slapd stop
and then start the Kolab bootstrap setup:
sudo kolab_bootstrap -b
and proceed with configuration for your server/domain.
Then restart all the services (e.g. sudo /etc/init.d apache2 start).
Notes: Kolab uses its own server components, and it is best to run Kolab on a dedicated server. However, it is possible to run other servers on the same machine, as long as you choose alternate ports if the server modules conflict.

You can choose an integrated theme or select individual components of the login screen/process.
GRUB boot manager settings
- If you have multiple operating systems (OS) on your computer, you are likely using a GRUB boot manager to select which one to start at bootup. You can edit the options for GRUB from a GUI interface:
- System -> Administration -> Advanced -> GRUB Editor
- To edit the settings manually from the command line Terminal:
sudo nano /boot/grub/menu.lst
Default Applications
You can choose which program to use as your default program for a specific task.
- System -> Administration -> Default Applications

Removing Users
- Select the user you wish to remove
- Click the "Delete" button
Change your user groups
It is quite often necessary to have extra privileges to do certain tasks. These privileges are assigned to your user by belonging to certain groups. The tasks are allowed to be performed by any user belonging to the group associated with that task.
- Example: a "sudoer" is a user who can perform certain administative tasks, such as updating the system. To become a "sudoer" a user must belong to the "sudo" group.
- Applications menu -> System -> User Manager -> user -> Groups --> check sudo
To become an administrator, you must belong to the adm, admin, and sudo groups. To be a virtualbox user, you must belong to the virtualbox group. To change printer settings you must belong to lpadmin. To use the cdrom, you must belong to cdrom. To use hot-pluggable devices, you must belong to plugdev. To share Samba folders (on a Windows-based network), you must belong to sambashare. To access NTFS files using the virtual filesystem fuse, you must belong to the fuse group. To use many games, you must belong to the games group. The list is long, and not always obvious.
Unfortunately, while this is the feature that gives Linux such a high-level of security, it can also take diligence to remember to add your user to certain groups. It is not uncommon for programs and functions on your system not to work merely because you don't have privileges to do so because you forgot to add your user to the appropriate group(s).
Of most importance, you must already be an administrator in order to change membership in groups. Therefore, if you create a new user and intend to give that user administrative privileges (by assigning the user to the administrative groups), you must do so from your original administrator account (the one you set up at installation) or from another administrative user account.
Timekpr (Parental controls)
Timekpr is a program to track and control the computer usage of user accounts.
- If updating, remove any prior versions:
sudo dpkg --purge timekpr
- Add the timekpr third-party repositories:
deb http://ppa.launchpad.net/nedberg/ubuntu jaunty main deb-src http://ppa.launchpad.net/nedberg/ubuntu jaunty main
- Install:
sudo apt-get install timekpr
- When prompted which default display manager to use, select "gdm"
- Start:
- System -> Administration -> Timekpr Control Panel
Web content filtering
DansGuardian provides web filtering capability, similar to NetNanny. It is useful for limitng objectionable content in publicly accessible workstations, or for filtering objectionable content for younger users. It integrates with ClamAV, and uses several criteria for filtering websites (which is difficult to modify). It is used with Tinyproxy (best for individual users) or the Squid proxy (best for a network server). Install:
sudo apt-get install dansguardian tinyproxy
- or
sudo apt-get install dansguardian squid
See these installation instructions for setup details. In brief,
- Edit the dansguardian configuration file:
sudo nano /etc/dansguardian/dansguardian.conf
- comment out the UNCONFIGURED line:
#UNCONFIGURED
- If using tinyproxy instead of Squid, change the proxyport to 8888:
proxyport 8888
- Reinstall dansguardian:
sudo apt-get install --reinstall dansguardian
- Set your browser to use the localhost:8080 proxy. For example, in Firefox:
- Firefox -> Edit -> Preferences -> Advanced -> Network -> Settings
- Manual proxy configuration -> HTTP proxy: localhost -> Port: 8080
- A Webmin module is available to administer settings. Also, a GUI to change Dansguardian settings called Webstrict is in development.
- A GUI for use with IPCop (based on the webmin module) is also available.
Working with Menus
Create an encrypted folder
With Ubuntu, you can create a folder whose contents are encrypted. See these instructions.
Printers
The new CUPS interface recognizes many printers. Specific printers not recognized can often be installed using instructions found at the Linux Foundation OpenPrinting database.
Add a Printer
- System -> Administration -> Printing -> New Printer -> New Printer
Most of the time, your printer (if connected and turned on) will be detected automatically.
My network printer with its own IP address at 192.168.0.124 was correctly installed at
- socket://192.168.0.124:9100.
You can also choose printers on a Windows system via Samba and other types of networked printers, in addition to directly connected printers.
Use CUPS web interface
From any web browser, go to the URL:
- http://localhost:631
Create a symlink from a file to another location
ln -s /path/to/source /path/to/destination
If /path/to/destination require superuser rights, use:
sudo ln -s /path/to/source /path/to/destination
This is similar to, but more powerful than, creating Shortcuts, with which former Windows users may be familiar.
Assign a root password
To be able to log in as root directly, you must assign a root password. This can be done with:
sudo passwd root
Afterwards, you can use
su
to get a root prompt. You would then use the root password.
Get a root prompt without using a root password
If you have not set a root password (or don't know it), you can obtain root user privileges anyway. From the command-line Terminal:
sudo -s
- or
sudo su
- or
sudo bash
You will use your own user password instead of a root password.
You could also get a prompt to become any other user on the computer by typing:
sudo su <username>
Use the File Manager as root
gksudo nautilus
Manually Mount and Unmount a device
To manually mount a device:
mount /dev/hda
replace /dev/hda with the location of the device.
To manually unmount a device:
umount /dev/hda
replace /dev/hda with the location of the device.
Windows Compatibility
Mounting NTFS Partitions (with read/write privileges)
Find out the name of your ntfs partition:
sudo fdisk -l
Method 1: In this example, the NTFS drive is listed by fdisk as /dev/sda2, but yours may differ.
Make a mount point for the drive:
sudo mkdir /media/WindowsNTFS
Edit fstab:
sudo nano /etc/fstab
Comment out the automatically added lines by Ubuntu installation:
#/dev/sda2 auto nouser,atime,noauto,rw,nodev,noexec,nosuid 0 0 #/dev/sda2 /mnt auto user,atime,noauto,rw,nodev,noexec,nosuid 0 0
and instead add the line:
/dev/sda2 /mnt/WindowsNTFS ntfs-3g quiet,defaults,rw 0 0
Note: There are many ways to mount the drive, depending on your needs. The fstab file controls this process. See How to edit and understand fstab and Intro to using fstab.
In this example, I indicated that the file system was an ntfs-3g filesystem, so did not use the auto option (which detects the filesystem automatically). I used rw to specify read/write privileges for all users, but umask=0 and umask=000 are accepted by some kernels.
Method 2:
Edit fstab:
sudo nano /etc/fstab
When Ubuntu installation finishes, it mounts all ntfs partitions automatically with ntfsprogs, adding a line similar to the following to fstab:
UUID=8466268666267956 /media/sda1 ntfs defaults,gid=46 0 1
Change this line to:
UUID=8466268666267956 /media/sda1 ntfs-3g defaults,nls=utf8,locale=zh_CN.UTF-8,rw,gid=46 0 1
In this example, I have a Chinese-language Windows installation on my first partition, so I set the locale parameter (locale=zh_CN.UTF-8) so that my Chinese documents can display correctly. Setting rw (same as umask=0 or umask=000) lets me read/write the partition without sudo. gid=46 specifies that the drive will belong to the group of hot-pluggable devices (plugdev) and is not necessary unless your ntfs drive is a hot-pluggable one (such as an external USB drive). nls=utf8 is the default and is optional for most ntfs users, but there are other options for Chinese (and other specialized character-set users).
Mounting FAT32 Partitions
Follow the above instructions, but use vfat instead of ntfs-3g.
In other words, if you have made a mount point directory /mnt/WindowsFAT32 and your FAT32 drive is /dev/sda3, then edit the /etc/fstab file to include the line:
/dev/sda3 /mnt/WindowsFAT32 vfat quiet,defaults,rw 0 0
Synchronize clock to network time server
The Network Time Protocol (NTP) allows time synchronization of your computer to time servers on the Internet.To enable it:
- Applications menu -> System Settings -> Date & Time
- Check the "Set date and time automatically" option
- Choose an ntp time server near you.

Install Latest Nvidia/ATI drivers
Upon initial installation and after the first reboot, you will be prompted whether to use the current proprietary nVidia drivers. If you wish to use them, follow the prompts.
Fix Intel 915 resolution problem
sudo apt-get install 915resolution
Screen Keeps Flickering
If you have an Intel Corporation Mobile 915GM/GMS/910GML card, your screen may flicker every 5-10 seconds. To prevent this:
- System -> Administration -> Advanced -> Service Manager
- Uncheck "Detect RANDR (monitor) changes"
Reconfigure xserver-xorg
sudo dpkg-reconfigure xserver-xorg
xorg.conf
Before installing any driver for ATI or nvidia, please make backup xorg.conf before following this method.
sudo cp /etc/X11/xorg.conf /home/user
If you have edited this file but would like it to be automatically updated again, run the following command:
sudo dpkg-reconfigure -phigh xserver-xorg
If you want to try this xorg.conf after installing the driver, you must back up your xorg.conf as following. And then, edit /etc/X11/xorg.conf in text editor. Add or modify this xorg.conf sample.

Installation of ATI and nVidia Graphics drivers
nVidia Driver
If you have problems with nVidia drivers after upgrading, check this guide for solutions to common problems with nVidia.
- Please make a backup of xorg.conf before following this method.
Install the nvidia-settings package:
sudo apt-get install nvidia-settings
Download nVidia driver at http://www.nvidia.com/Download/index.aspx?lang=en-us and place it at your home directory. After downloading, close all open windows and press <CTRL> <ALT> F1. Log in and enter password and then just connect to the internet. Press <ALT> F2, kill gdm or kdm season by entering sudo killall <your desktop manager>, example:
sudo killall gdm
Install the nvidia driver. Make sure you are in the nvidia driver directory. If you downloaded it and placed it on the Desktop, make sure to change directories first.
cd Desktop
To install it, enter /NVIDIA-Linux-x**-***.**-pkg1.run. For example, if you downloaded Nvidia version 173.80:
sudo sh NVIDIA-Linux-x86-173.80-pkg1.run
choose yes to any verbose response. After you are finished installing the driver, reboot your computer.
sudo reboot
ATI Driver
If you have problems with ATI drivers after upgrading, check this link for solutions to common problems with ATI.
Monitors / Displays
Turn off power saving
Even when on AC power, the power saver feature of Ubuntu sometimes changes the screen brightness to the battery setting on laptops. This is a problem with the ACPI power management module.
- To access the Guidance Power Manager module, click on the power icon on the desktop taskbar.
- Change the brightness setting for "Battery powered" to maximum.
You can also turn off power management settings (invoked when the computer is idle):
- System -> Administration -> Display -> Power Control -> uncheck "Enable display power management"
Configure Dual Monitors with nVidia
- Make sure that the nVidia driver has been installed and is functioning properly on your first screen. Also, make sure both monitors are connected.
- Open the command-line terminal Konsole and type:
sudo nvidia-settings
- Select "X Server Display Configuration".
- You should see 3 boxes (2 if your card doesn't have an S-Video out). From here you can configure all of your card's outputs.
- Check the "(Disabled)" box.
- Select "Configure...".
- The most common choice is TwinView. Select it.
- Setup the desired screen resolutions and positions of your two active displays.
- The new display will likely have resolution set to "Auto" to match your first. Change this if you wish.
- Leave the first screen's position as "Absolute" and set your second display's position relative to that.
- "Clone" means the same output on both.
- Once you are satisfied with your settings, hit Apply to test them.
- Note: if your displays are side-by-side, the kicker may extend across both screens as well as any maximized applications. This will be corrected when the X server is restarted.
- If everything else is ok, hit "Save to X Configuration File". Now hit Ctrl+Alt+Backspace to restart X. You now have 2 screens!
- (The NVIDIA X Server Settings application can be also found in K -> System Settings to change settings later, but this does not always work because settings need to be changed as the root user.)
- Troubleshooting: if the X server fails to reload you can recover your old X configuration. In a terminal:
sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf
Hard Drives and USB Storage
Optical Drives
Printers & Scanners
The new CUPS interface recognizes many printers. Specific printers not recognized can often be installed using instructions found at the Linux Foundation OpenPrinting database.
Brother printers
Most Brother printers are auto-detected or can be installed directly from the CUPS interface. For information on a specific model, see the Linux OpenPrinting site.
Sound
Many programs require ALSA sound. If you are not hearing sound, try selecting ALSA as the default sound system:
- System -> Administration -> System Settings -> Sound
Also check your program's preferences section to make sure ALSA is selected. This is necessary for many multimedia packages, for example.
Pulse Audio
Jaunty has Pulse Audio version 0.9.14 and Pulse Audio Volume control 0.97 in the repositories. On my system I had to install them:
sudo apt-get install pulseaudio pavucontrol padevchooser
I then had to enable my user to belong to the pulseaudio groups:
- System -> User Manager -> user -> Groups ->
- check pulse pulse-access and pulse-rt
Configure Pulse Audio:
- System -> Settings -> PulseAudio Preferences Sound Audio preferences
I also had to set PulseAudio as my default sound system:
- System -> System Settings -> Multimedia -> Device Preference
- Note: Unfortunately, not all programs like PulseAudio. Many programs require special plugins for PulseAudio. YMMV. Pulse Audio still has many bugs. Installing PulseAudio disables ALSA for many soundcards. You may end up with no sound at all if you install PulseAudio. If this happens you may have to uninstall it.
Airport Express
Airport Express with Pulse Audio
The Airport Express (AEX) is a network device with an audio output jack that can be connected to speakers or an amplifier. You can stream audio over the network (wired or wirelessly) to (or from) this device.
These capabilities require the newest version 0.9.15 of Pulse Audio and Pulse Audio Volume Control 0.98, as well as pulseaudio-module-raop (for Airport Express). Instead of (or after) installing the default 0.9.14 packages from the Jaunty repositories, obtain them by adding the repositories from this Launchpad site:
deb http://ppa.launchpad.net/themuso/ppa/ubuntu jaunty main deb-src http://ppa.launchpad.net/themuso/ppa/ubuntu jaunty main
- then download the GPG key here
- and save it as themuso.gpg.
- then install the repository key and update:
sudo apt-key add themuso.gpg sudo apt-get update
then install:
sudo apt-get install pulseaudio pavucontrol paprefs padevchooser pulseaudio-module-raop
Then configure Pulse Audio:
- Menu -> Settings -> PulseAudio Preferences Sound Audio preferences -> Network Access
and check both:
- Make discoverable network sound devices available locally
- Make discoverable Apple Airtunes devices available locally
Note: Make sure your firewall is not blocking ports 5353, 5000, and 6000.
My AEX is discovered, but I got no sound through it until I selected it as the default sink (output) from the PulseAudio Device Chooser.
- K menu -> Multimedia -> PulseAudio Device Chooser -> Manager -> Devices -> Sinks
- I then noted the name of my Airport Express device to be raop.Base-Station-e60157.local, so I entered that as the sink:
- PulseAudio Device Chooser -> Default sink -> Other -> raop.Base-Station-e60157.local
Now, any devices (or multimedia players) setup to play through PulseAudio will play through the stereo attached to the Airport Express.
GSTransmit
GSTransmit is a tool to allow GStreamer-based utilities to stream output to an Apple AirTunes Device (such as the Airport Express), without using Pulse Audio. It is available as a self-installing .deb file from the website.
raop-client
Another method to stream audio to the Airport Express without Pulse Audio uses raop-client, a tool written in Ruby. See information here.
Airfoil
You can stream media from a PC running Windows or Mac OS X that is connected to an Airport Express network to your Ubuntu Linux desktop, using Airfoil. (Unfortunately you cannot send media output from Ubuntu to the Airport Express network, only receive from it.) This can be useful in a distributed multimedia system, for example, in which your Ubuntu PC is connected to a media center. You must be running Mono. You can download the .deb package at Rogue Amoeba. Installation instructions are at Rogue Amoeba Linux support.
Mice
Activate side-mouse-buttons in FireFox
Adding two lines to xorg.conf will activate side-mouse-buttons in FireFox.
- This should work with most brands of the 5-button mouse. Here is a list of mice that worked with this instruction.
- Logitech MX310
- Logitech MX510
- Logitech MX518
- Logitech MX700
- Logitech MX Revolution
- Intellimouse Explorer (first edition)
- Razer Copperhead
- Backup X.org configuration file
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
- Modify the X.org configuration file
kdesu kate /etc/X11/xorg.conf
- Find the Input Device section for your mouse and add two lines as shown below.
- You may also increase the number of buttons if your mouse has more than 7 -- just fix the rest of the section based upon the number of buttons.
- Note: "back/forward", "wheel click" & "tilt left/right" all count as buttons
- Change:
Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device" "/dev/input/mice" Option "Protocol" "ExplorerPS/2" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "true" EndSection
- to:
Section "InputDevice" Identifier "Configured Mouse" Driver "mouse" Option "CorePointer" Option "Device" "/dev/input/mice" Option "Protocol" "ExplorerPS/2" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "true" Option "Buttons" "7" Option "ButtonMapping" "1 2 3 6 7" EndSection

For Synaptics Touchpads:
sudo apt-get install gsynaptics
For more info, see the Ubuntu help wiki.
Remote Controls
LIRC (Infrared Remote Controls)
LIRC (Linux Infrared Control) allows you to use most infra-red remote controls. This can be installed from Applications -> Add/Remove Packages -> Settings -> Infrared Remote Control
- or
sudo apt-get install lirc
Bluetooth
BlueZ is the package that allows Bluetooth connectivity in Ubuntu Linux. This package is included within the current kernel of Ubuntu. To add utilities to check whether your Bluetooth adapter's firmware is current, install:
sudo apt-get install bluez-utils bluez-firmware
then run
sudo dfutool
WiiMote
The Wiimote (Wii Remote Control) uses both Bluetooth and Infra-red technology. It communicates with Ubuntu Linux using the incorporated BlueZ Bluetooth drivers and/or LIRC drivers. (It can function with Bluetooth alone, however.) You will need a Bluetooth receiver on your PC (such as a Bluetooth USB stick or built-in Bluetooth receiver, for example). (Note: not all Bluetooth receivers will work with the Bluez drivers. Check this list or test yours first.)
- Install the cwiid Wiimote controller package and the lswm Wiimote discovery package:
sudo apt-get install wminput lswm
- Install the drivers (or just reboot):
modprobe uinput
- Note: You can also add uinput to the modules files so it loads automatically at bootup:
sudo echo "uinput" >>/etc/modules
Run (while pressing button 1/2 on the Wiimote):
sudo wminput
For more info, and to learn how to enable the infra-red functions, see this guide.
USB
Wireless Cards
Atheros Cards
Atheros Wireless cards should work automatically with the new kernel by installing the proprietary driver. At installation, after the first reboot, you will be prompted whether to use the proprietary drivers.
It should no longer be necessary to install the following package:
sudo apt-get install madwifi-tools
These instructions for the Atheros 802.11 b/g integrated card are here for reference only (or if you wish to install them manually instead):
- Download the latest 'snapshot' driver from Madwifi. When I was doing it, the version was:
madwifi-hal-0.10.5.6-current.tar.gz
- Extract the files
- Make sure your linux headers and build-essential packages are installed:
sudo apt-get install build-essential sudo apt-get install linux-headers-$(uname -r)
- Unload any drivers already running.
sudo ifconfig ath0 down sudo ifconfig wifi0 down
- Change to the directory where you extracted the driver.
cd <directory_where_driver_unzipped>
- From that directory, run the installation scripts:
cd scripts sudo ./madwifi-unload sudo ./find-madwifi-modules.sh $(uname -r) cd ..
- Complete the installation by compiling the source and installing it.
sudo make sudo make install
- Add the installed drivers to your system.
sudo modprobe ath_pci
Following this, Network Manager was able to see the wireless card and I was able to configure everything else (WEP / WPA key, etc.) from there.
Complete instructions are available at MadWifi UserDocs.
Atheros AR242x
Alternate instructions for installing the Atheros AR242x card are here.

- Note: samba-tools and system-config-samba are optional.
- Modify Samba settings.
- Method 1:
- System -> Administration -> Advanced -> Samba
- (Note: this is available only if you installed system-config-samba.)
It is recommended that your user be a member of the sambashare group, as well.
- Method 2:
- Enable File Sharing Server With User Login (Very Reliable Method)
- Do the following on the machine that has the files to be shared:
- Add current user to Samba:
sudo smbpasswd -a username
- (replacing username with your login username)
- Open the samba config file:
sudo nano /etc/samba/smb.conf
- Add the directories to be added (right at the end) in the following format:
[Pictures] path = /home/username/<folder_to_be_shared>
- (Replace username with your username and <folder_to_be_shared> with the folder you want to share)
- Press CTRL+X and then Y to save.
- Restart Samba
sudo /etc/init.d/samba restart
- On Windows access the folder in the following format in Windows Explorer:
\\192.168.x.x
- (replace 192.168.x.x with the actual IP address of your server which is serving the folder)
- On Linux type the following in Konqueror or Nautilus:
smb://192.168.x.x
- (replace 192.168.x.x with the actual IP address of your server serving the folder)
Note: If you use Sharing in KDE's System Settings panel, be aware that there is a small bug, reported here. In brief, you need to comment out/delete any instances of these two lines in /etc/smb.conf :
case sensitive msdfs proxy
Recognizing Win98 machines
Microsoft networking is extremely quirky. To enable recognition of PCs with Windows 98, edit your Samba configuration file:
sudo nano /etc/samba/smb.conf
Then add the following lines to the file:
[global] # THE LANMAN FIX client lanman auth = yes client ntlmv2 auth = no

Network Manager
Network Manager has been redesigned for Intrepid Ibex and now works quite well. You should not require other network managers, and, in fact, more than one network manager can cause conflicts.
It can be accessed from the tray icon.
Manual configuration from the command-line
3 steps for WEP:
sudo iwconfig eth[N] essid [SSID] sudo iwconfig eth[N] key restricted s:[PASSWORD] sudo dhclient
WPA is more complicated:
su mkdir /etc/wpa_supplicant cd /etc/wpa_supplicant echo network = { > wpa_supplicant.conf echo ssid="SSID" >> wpa_supplicant.conf echo key_mgmt=WPA-PSK >> wpa_supplicant.conf echo psk="PRESHAREDKEY" >> wpa_supplicant.conf echo } >> wpa_supplicant.conf cd /etc/network vim interfaces
Now add after "auto eth[N] ..." & "iface eth[N] .." (press 'i'):
wpa-driver wext # or whatever driver your network card needs wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
Save the file ('Esc', ':x', 'Enter') and restart your system.
Remote Access
There are several methods of remote access. VNC sharing allows you to view and control a remote computer's desktop. (Windows users use a similar proprietary protocol called remote desktop protocol (RDP)). XDMCP allows a complete remote X-windows based login. Remote connections are hazardous unless proper security precautions are taken to prevent unauthorized logins and to ensure encryption of transmitted data.
SSH
Secure Shell or SSH is a network protocol that allows data to be exchanged over a secure channel (or "tunnel") between two computers. Encryption provides confidentiality and integrity of data. SSH client is installed by default in Ubuntu so you can connect to another computer that is running a SSH server.
Connect to a remote SSH server
From the command-line terminal
Install the OpenSSH client (if not already installed):
sudo apt-get install openssh-client
From the command-line Terminal type:
ssh -C <username>@<computer name or IP address>
- Note: The -C option indicates compression, which speeds up transmission through the tunnel.
For example:
ssh -C [email protected]
- or:
ssh -C [email protected]
- or
ssh -C 192.168.1.1 -l mike
- Note: -l specifies the login id.
If the SSH server is listening on a port other than port 22 (the default), you can specify that in your connection (with the -p option). For example, if the SSH server is listening on port 11022, connect:
ssh -C [email protected]:11022
- or
ssh -C remote.computer.xyz -p 11022 -l joe.friday
If you have made a public/private key using ssh-keygen, the private key must be stored in /home/user/.ssh. The key should be accessible only to user
sudo chmod 600 /home/user/.ssh/identity
- or
sudo chmod 600 /home/user/.ssh/id_rsa
To login with the key:
ssh -C remote.computer.xyz -p 11022 -l joe.friday
Note: You can run the command as a menu item, but the command must be "run in terminal."
Port forwarding through SSH
See Using SSH to Port Forward for full details.
In brief, use
ssh -C <remote ip> -p <SSH tunnel port> -L <local port>:<remote computer>:<remote port> -l <user>
This specifies that any communications from your computer (localhost) going out through <local port> will be transmitted securely through the the SSH tunnel port. To use VNC through the tunnel, you would use an application like Krdc or Vinagre:
krdc vnc:/localhost:<local port>
Note that for VNC, the default <local port> is 5900. In general, a remote VNC server (such as Krfb) is also listening on the default <remote port> 5900 as well. The default <SSH tunnel port> is 22, as discussed above. All these can be changed, however, if you desire greater security.
For me, I noticed that I had to set <remote computer> to be the internal LAN IP address of the remote computer (such as 192.168.1.155) instead of the remote router's IP address, which is specified in <remote IP>. (If the remote computer has a static IP address (i.e. is directly connected to the Internet without an intervening router), then <remote computer> and <remote ip> would be the same.)
Example: For extra security, my SSH Server uses <SSH tunnel port>=11022. I want to VNC to a remote computer on a remote LAN with a router whose IP address is <remote ip> = 244.205.123.123. The remote computer to which I want to connect has a static IP address within the remote LAN of <remote computer> = 192.168.1.155. I have set up a Krfb VNC server on this computer that is listening on <remote port> = 6912 (instead of the default 5900). I setup port forwarding on the router of this remote LAN to forward port 6912 to this server computer. I want to VNC to this remote computer from my laptop, through the Internet. My laptop VNC client (Krdc) will use the default <local port> = 5900. My name is <user> = joe.friday. This is my story.
ssh -C 244.205.123.123 -p 11022 -L 5900:192.168.1.155:6912 -l joe.friday krdc vnc:/localhost:5900
If you have set up a private/ public key pair with a passphrase, or if your SSH server requires a passphrase, of course, you will be prompted for the passphrase after issuing the SSH command.
Note: Port forwarding assumes that the ports are also forwarded through the router(s) and through any firewalls. See the documentation for your router(s) and firewall to learn how to do this. The advantage of SSH tunneling is that only the <SSH tunnel port> needs to be open and forwarded by a router. All encrypted communications will go through your router using this single port. This is what makes the communications secure.
PuTTY
PuTTY is a GTK-based GUI client-interface for SSH connections and eases the setup for port forwarding, SSH public key authentication, and automated login.
sudo apt-get install putty
A user would run Putty to create the SSH tunnel (instead of the ssh command) and then run Krdc. Note that PuTTY security keys are not generally compatible with SSH security keys. I was not able to get PuTTY to work with Krdc.
Connect using SSH Agent
With SSH Agent you can automate the use of public key authentication and open an XDM or VNC session using a script. See this tutorial.
Setup an SSH server
Install the OpenSSH server:
sudo apt-get install openssh-server
Note: The OpenSSH server can also be installed when doing a server installation as an option from the LiveCD.
Note: An OpenSSH server can also be set up on a Windows server using Cygwin. See these instructions.
Limit authorized SSH users
See How to limit the user accounts that can connect through SSH.
OpenSSH Public Key Authentication
See this OpenSSH Public Key Authentication Tutorial.
In brief, it is necessary to generate a public / private key pair. On your client machine, generate the pair:
ssh-keygen
A prompt asks for a passphrase. If you wish to use SSH without a password from a secure client (to which no one but you has access), leave the passphrase blank. If you enter a passphrase, you will be asked for this passphrase each time you use the SSH client. By default, a 2048-bit RSA key pair is generated and stored in the /home/user/.ssh folder. The private key is named id_rsa and is meant to stay in that folder. The public key is id_rsa.pub and is meant to be copied to the SSH server. On the SSH server, there is a similar folder /home/user/.ssh (for whichever user is hosting the SSH server). In that folder is a file called authorized_keys2. The contents of id_rsa.pub must be copied into that authorized_keys2 file. (You can use a text editor or can concatenate the files with the cat command).
To keep keys private, they should be accessible only to user, the owner of the file. For example,
chmod 600 /home/user/.ssh/id_rsa
This makes the file only accessible to user. You could also make the entire .ssh folder accessible only to user:
chmod 700 /home/user/.ssh
VNC
Virtual Network Computing (VNC) mirrors the desktop of a remote ("server") computer on your local ("client") computer (it is not a separate remote login, as is XDMCP). A user on the remote desktop must be logged in and running a VNC server (such as Krfb or Vino). Keyboard and mouse events are transmitted between the two computers. VNC is platform-independent 鈥? a VNC viewer on one operating system can usually connect to a VNC server on any other operating system.
Krfb VNC server
Krfb is the default VNC server in Kubuntu/KDE (use Vino in Ubuntu/Gnome). It can be started from:
Applications menu -> Internet -> Krfb
- You can change the listening port in the Network section. Your router must forward this port to your computer (or you must use an SSH tunnel). A user trying to connect must know the listening port as well and explicitly specify it during the VNC connection.
- You can accept uninvited connections in the Security section. You can require a password for these connections.
- A user can connect using Krdc or any other VNC client.
How to use Krfb with SSH tunneling securely
It is less secure to leave Krfb's listening port open to the Internet, even with a password. (This can expose you to password cracking attempts.)
It is more secure to use SSH to tunnel your VNC connection. Under SSH port forwarding, Krfb's listening port is the <remote port>. To increase security, this listening port can be changed from the default 5900. Only the Kfrb server and the SSH client need to specify the <remote port> in a secure connection.
X11VNC Server
- To install an X11VNC server to share your desktop with other computer, type each of these commands in order:
sudo apt-get install x11vnc mkdir ~/.vnc x11vnc -storepasswd YOUR_PASSWORD ~/.vnc/x11vnc.pass echo "/usr/bin/x11vnc -rfbauth ~/.vnc/x11vnc.pass -o ~/.vnc/x11vnc.log -loopbg -display :0" > ~/.kde/Autostart/x11vnc.sh chmod +x ~/.kde/Autostart/x11vnc.sh
- You can test the server by running the shell script:
~/.kde/Autostart/x11vnc.sh
- and after restarting KDE, the script should start the VNC server automatically.
- For customization of x11vnc server, edit the commands in the x11vnc.sh file enter after viewing "man:/x11vnc" in Konqueror, where a description of parameters for x11vn is given.
- See Ubuntu help on VNC for more info on other VNC servers.
Using VNC with SSH
See Using VNC for additional information.
Krdc VNC client
Krdc is the default VNC client in Kubuntu. Use Vinagre in Ubuntu/Gnome.
- K-Menu -> Internet -> Krdc
- To connect to a VNC server, simply type
krdc vnc:/<remote IP>
- If the remote (Krfp) VNC server is using a <remote port> other than the default 5900 port, use
krdc vnc:/<remote IP>:<remote port>
- Krdc can also connect to a Windows server using RDP (Remote Desktop Protocol).
krdc rdp:/<remote IP>:<remote port>
Using Krdc VNC client with SSH
See this howto for an automated setup using a script (it did not work for me, but it might for you).
In brief, you would initiate an SSH tunnel with port forwarding using Putty or the command line:
ssh -C <remote ip> -p <SSH tunnel port> -L <local port>:<remote computer>:<remote port> -l <user>
- then you would start Krdc:
krdc vnc:/localhost:<local port>
<local port> will usually be the default 5900, in which case you could simply use
krdc vnc:/localhost
XVNC4Viewer VNC Client
You can also install XVNC4Viewer (if you prefer it over Krdc) using:
sudo apt-get install xvnc4viewer
FreeNX
FreeNX is a remote desktop display server/client solution that natively incorporates SSH tunneling (unlike VNC). It is therefore more secure than VNC (unless VNC is coupled with SSH tunneling).
FreeNX Server
The Free server .deb package can be downloaded from No Machine free server downloads.
- Alternatively, add the following repositories:
deb http://ppa.launchpad.net/freenx-team/ubuntu intrepid main deb-src http://ppa.launchpad.net/freenx-team/ubuntu intrepid main
- Install the package:
sudo apt-get update sudo apt-get upgrade sudo apt-get install freenx
FreeNX Client
Download the self-installing .deb file from No Machine Client downloads.
XDMCP
XDMCP allows a separate remote login by an authorized user. This login is separate from the local user.
- XDMCP is not secure over the Internet and should only be used within a LAN. It cannot be tunnelled through SSH. It is turned off by default in Ubuntu. To enable it, edit the KDE configuration file:
kate /etc/kde3/kdm/kdmrc
- Find and change the line from false to true so that it reads:
[Xdmcp] Enable=true
Telnet

WebHuddle
WebHuddle is a free, open source Java-based browser client (and server) for web meetings.
Security
Ubuntu by default is a fairly safe system. However, if you intend to use Ubuntu as a server, or for critical applications in which loss of data (by accident or by malicious intrusion) would be disastrous, you should learn how to make Ubuntu more secure. A good introduction to Ubuntu Security Best Practices is available.
Firewall
Network communications go through "channels" called ports. You can restrict which ports are available ("open") for network communications, creating a barricade to unwanted network intrusion. Firewalls do this job for you. But I guarantee that if you install one before you know how to use it that one or more networking programs on your system will stop working. Read every bit of documentation about a firewall before installing it -- you won't regret the time invested. All of these packages modify iptables, which is the set of rules that controls network access in and out of your computer. (You can modify iptables manually from the command line, as well, but if you are that much of an expert, you probably don't need this guide.)
Firestarter
Firestarter is an intuitive firewall manager used to set the iptables values which provide firewall capabilities in Linux (including Ubuntu). It has a very easy-to-use GUI.
sudo apt-get install firestarter
Guarddog
Guarddog is a GUI firewall configuration utility that has been used for KDE. It has a complex array of configuration, and is difficult to use for some beginners.
sudo apt-get install guarddog
Uncomplicated Firewall
Uncomplicated Firewall is installed in Ubuntu Intrepid Ibex by default, but is disabled by default. It is configurable through the command-line interface (i.e. Konsole). See this forum thread , or this usage tutorial for tips on how to set up and use it. If not installed, it can be installed:
apt-get install ufw
Gufw
Gufw is a graphical user interface for Uncomplicated Firewall. A self-installing .deb file is available from the website. For sample screenshots see this UbuntuGeek guide.
Anti-virus
If you are running a file server, interface frequently with Windows drives, or use virtualization, you will want a virus checker for your Windows files.
ClamAV
ClamAV is the open source virus tool for Linux. To install ClamAV with a KDE frontend:
sudo apt-get install klamav
Anti-spam
Spam Assasin
SpamAssasin is written in perl, and is mostly for use with a server (such as a groupware server or Apache).
Rootkit checkers
Rootkits are malicious trojan-like programs to allow an intruder to become a root user and therefore have complete administrative control over the system. There aren't many rootkits in the wild for Linux. Still, this is a growing security problem (especially in other operating systems) and it is a matter of time before more rootkits appear in Linux. Checking for rootkits isn't always successful from a system that is already infected. Your rootkit checker should therefore be run from another system, or a USB pendrive with a Ubuntu LiveCD installation. See the rootkit checker manuals for instructions how to do this. If you are infected with a rootkit, you must backup all your files and re-install your system. (Thank goodness this is easy with Ubuntu, unlike with other operating systems).
Chkrootkit
Chkrootkit checks locally for signs of a rootkit. See the chkrootkit manual for usage instructions.
- Install:
sudo apt-get install chkrootkit
- Run:
sudo chkrootkit
Rootkit Hunter
Rootkit Hunter is compatible with (K)ubuntu systems. See the usage instructions.
- Install:
sudo apt-get install rkhunter
- Run:
sudo rkhunter
Security hardening
Nmap
Nmap is a free open source utility for network exploration (including showing open ports and running services) and security auditing. Install:
sudo apt-get install nmap
Scan your own PC:
nmap localhost
(Once you have found out which ports are open, use a firewall to close the ones you don't want open.)
Nmap GUI
Install:
sudo apt-get install nmapfe
Or you can try
Install:
sudo apt-get install zenmap
Nessus
Nessus is a proprietary comprehensive vulnerability scanning suite that is free for personal, non-enterprise usage. See the website for details.
AppArmor
AppArmor is a set of security enhancements developed by Novell for SUSE Linux. It is installed in (K)ubuntu by default.
Disable AppArmor
AppArmor can prevent some services from running as expected. To disable it:
/etc/init.d/apparmor stop update-rc.d -f apparmor remove apt-get remove apparmor apparmor-utils
SELinux
SE Linux (Security Enhanced Linux) is an NSA (US National Security Administration) recommended set of tools for enhanced security in Linux systems. It enforces strict access controls (privileges) and is meant for mission-critical installations. It is not suitable for the casual desktop user. It was first available in Hardy Heron and is being updated for Intrepid Ibex. It is not compatible with AppArmor (which must first be removed).
sudo apt-get install selinux
Servers
You can have a GUI desktop with an Ubuntu Server. If you intend such as setup (or want to use packages that require server capabilities, such as Drupal with Apache, etc.), then it is best to install Ubuntu Server edition first and then install the Ubuntu (Gnome) desktop afterwards. For complete information see the Ubuntu Server Guide.
Note that Intrepid Ibex is not a long-term support version, and there are many changes from Hardy Heron to Intrepid Ibex, including some new bugs in the Intrepid Ibex desktop. Unless new features, such as Xen (virtualization) support or the Tomcat (Java) server, are desired, many users recommend Hardy Heron's stability whenever a server/desktop combination is intended.
- Download the latest Ubuntu Server ISO image from Ubuntu downloads.
- See this guide for burning the ISO image to a CD.
- Use the CD for installation of the server.
LAMP server installation
During server installation, you will have the option of installing a LAMP (Linux, Apache, MySQL, pHp) server stack. Many (but not all) open source servers use this integrated server stack. Drupal, for example, needs to have a LAMP server installed. If you intend to install a groupware server, however, make sure it is compatible with a LAMP server stack before choosing this option. Many groupware servers will install LAMP (or their own variation) automatically, so you do not need to install the LAMP stack. Others will install and use postgreSQL instead of MySQL, so you would not need to install a LAMP server.
Other servers
During server installation, you can choose other servers to install, as well. These include a Mail server (Postfix with Dovecot), a DNS server (bind9), the OpenSSH server, a print server, a Tomcat Java web server, a Samba file server (for use with Windows networks), and a virtual machine host (Xen). Again, if you are using a groupware solution, you should be careful about installing these services, as they may conflict with similar (but competing) servers which the groupware solution will install by default.
OpenSSH server
OpenSSH allows encrypted communications through a designated secure port. The OpenSSH server can be installed as an option during the Ubuntu Server LiveCD installation. Also see setting up an SSH server.
Postfix (Mail Server)
Postfix is a free open source mail server. It can be installed as the "Mail server" option when installing the Ubuntu server from the LiveCD. It interfaces directly to Dovecot, the free open source IMAP and POP3 server.
Bind9 (DNS server)
BIND DNS servers are the most commonly used on the Internet. Bind9 is the current edition and is installed by selecting the "DNS server" option when installing Ubuntu server from the LiveCD. See the usage instruction here.
Apache Tomcat (Java server)
Tomcat is a free open source platform from Apache which provides a "pure Java" HTTP web server environment for Java code to run (see here for more info).
It is not part of the Apache2 web server. Installation can be done by checking the "Install Tomcat server" option at the time of the initial Ubuntu server installation from LiveCD.
Xen virtual machine host
Xen is a free open source virtualization platform that allows the host to run "guest" operating systems simultaneously (see here for more info). Xen implementation in the (K)ubuntu server is based on integration with KVM, the kernel-based virtualization platform in Linux. KVM integrates with QEMU components, which have been merged with Xen.
Note: KVM requires a 64-bit processor with a virtualization extension, i.e. an Intel VT or AMD-V CPU, therefore this package currently is successful only with the 64-bit Ubuntu server installation and on those CPUs.
Installation can be done by checking the "Install virtual machine host" option at the time of the initial Ubuntu server installation from LiveCD.
Print server
Ubuntu uses the CUPS print server, which is integrated into the desktop. Installing a print server in Ubuntu Server is necessary only if you do not intend to use a desktop (i.e. you intend a "headless" server). Because this guide is orientated towards users who will install a Ubuntu desktop on top of the server, please see Ubuntu server documentation for this option.
Apache2 Webserver with PHP and Perl support
To install an Apache webserver (but not the entire LAMP stack) with both PHP and Perl CGI support, see this guide.
Network Monitoring and Management
Monitor your network or datacenter with a framework of utilities. Comparable to IBM Tivoli (which can cost thousands of dollars), these solutions are generally available as either community or enterprise editions.
- Hyperic is an open-source network monitoring framework that can be used in either a datacenter or a cloud environment (it is used for Amazon Cloud). Both a free community version and a subscription enterprise version are available.
- Groundwork OpenSource offers a community edition that integrates other packages such as Nagios, Nmap, and others. There is a subscription enterprise version as well. It has its roots in a university setting.
- OpenQRM is the GPL-licensed, free open-source community successor to the very popular network monitoring solution Qlusters. It is available as a Debian/Ubuntu package. See the website for details.
- Canonical offers the Landscape network management service for $150 per node, with a free trial available.
- Zenoss is a commercial network monitoring subscription package (about $150/node) with a limited free "core" edition also available.
Nagios
Nagios is a free open source network monitoring solution. It is available as a package installation in Ubuntu. It is administered from a web interface (http://localhost/nagios) and is expandable using a large number of available plugins. Install:
sudo apt-get install nagios3
Add the Ubuntu desktop to a server
Once you have completed installation of your Ubuntu server, you can add an Ubuntu desktop to it. This can only be done as root.
- Login with the administrator login/password which you created during Ubuntu Server installation.
- Create a root user password
sudo passwd root
- and enter the password you intend to use for root
- Login with root user privileges
sudo -s
(Note: To use this command, your user must be part of the sudo group. Use your user's password, not the root password.)
- Update your server
apt-get update apt-get upgrade
- Install the Ubuntu desktop
apt-get install ubuntu-desktop
Go get some coffee. And some lunch. Perhaps a movie. Come back later. When you get back to the command line prompt after installation is complete, reboot. Now you will have an "Ubuntu server."
Internet Cafe software
Internet Cafe (or CyberCafe) software is specialized LAN-administration software that includes time usage monitoring, billing, and administration. It can also be used in schools, libraries, and organizations with multiple monitored workstations requiring usage limits.
OutKafe
OutKafe is a free, open-source, GPL-licensed cybercafe solution based on a postgreSQL database server stack. It is run on hundreds of sites. It is GTK-based.
OpenKiosk
OpenKiosk is a free open source multi-platform server/client solution for administering and monitoring groups of workstations, such as in libraries, school labs, and internet cafes. Installation is from source files. See the website for details.
CafePilot
CafePilot is a free multi-platform Java-based server/client solution for real-time monitoring and billing of Cybercafe workstations. A complete custom Ubuntu-based LiveCD server/multiple-client solution (including OS and many applications for unlimited workstations) is available for $100 here.
Enterprise Network Firewall
IPCop
IPCop is a free open source (GPL-licensed) firewall solution for use as an independent appliance (on a dedicated PC) in an enterprise network. It allows remote management and can protect multiple servers, including web and email servers. IPSec-based OpenVPN is supported. The CD image .iso and other files can be downloaded here. Installation instructions are on the website.
SmoothWall
SmoothWall Express is an award-winning, free, open source (with a GPL license) firewall solution for use as an independent appliance (on a dedicated PC) in an enterprise network. Download the installation CD .iso image here (server OS included), burn onto a CD, and install on a new, dedicated PC. Many features, however, such as VPN server, database access authentications, and content filtering are only implemented in a commercial version, however, and are not available in the community version.
Endian
Endian is a very robust, free, open source universal threat management appliance similar to IPCop and Smoothwall. It also incorporates OpenVPN. Like Smoothwall, Dansguardian is used for content filtering (and is included in the community edition). Commercial and hardware versions with some additional features, automatic updates, and professional support are available. See the website for details.
Tips & Tricks
Run Command
You can run any application in your path using the Run Command. Use Alt+F2.
Turn off Hot Keys
This is the most evil option on any operating system, in my opinion. A mis-stroke enables any number of random events. Unfortunately, this problem is pervasive in operating systems and is difficult to turn off.
- System -> Administration-> Advanced -> Input Actions -> General Settings -> check "Disable KHotKeys daemon"
- System -> Administration-> Advanced -> Input Actions -> Gestures Settings -> check "Disable mouse gestures globally"
If you wish to be selective about it (this doesn't often work, however), start by disabling unnecessary desktop hotkeys.
- System -> Administration-> Advanced -> Keyboard & Mouse -> Keyboard Shortcuts
Also, you may want to deactivate linking gestures to sticky and slow keys:
- System -> Administration -> Accessibility -> Activation Gestures -> uncheck "Use gestures for activating sticky keys and slow keys"
Note: You probably will have to disable hotkeys in many applications, as well.
- Hotkeys from the Synaptics Touchpad can be selectively turned off using this information from the Ubuntu documentation.
Run Ubuntu LiveCD from a USB pendrive
The Ubuntu LiveCD can be installed on and run from a USB pendrive. Settings can be "persistently" saved (but the LiveCD kernel modules can not be upgraded). Programs can be installed and run, however, and files saved to the USB drive. (The installed programs will remain installed). See these Pendrivelinux instructions. An Ubuntu Live CD is needed to do the install.
The USB "LiveCD" can also be used to install Ubuntu on computers (including netbooks) that do not have CD-ROM/DVD drives.
USB pendrives to be used to run Ubuntu should have a minimum of 2 Gb (preferably 4 Gb). If you wish to install a fast, fully functional Linux system on a pendrive that has less memory than that, use PuppyLinux.
Create a boot CD to allow booting from the USB drive
Many computers do not allow booting from a USB drive (but they do allow booting from the CD-ROM). You can create a CD-ROM using these Pendrivelinux instructions and set your BIOS to boot from this CD-ROM. When you boot from this CD-ROM, it will use the bootup files on the Ubuntu USB drive you previously created (in the step above).
USB Creator
You can make a "LiveCD" on a USB pendrive using USB Creator and either a LiveCD or an .iso version of the LiveCD stored on your hard drive. See these instructions or these PendriveLinux instructions. Install:
sudo apt-get install usb-creator
Associate default applications
- To assign the default DVD player (make sure you have enabled DVD playback capability first:
- System -> Administration-> Advanced -> File Associations -> x-content -> video-dvd -> Applications Preference order -> Add...
- then choose your favourite media player. There are similar options for Blu-Ray (video-bluray) and HD DVD (video-hddvd). Set each individually.
- To assign the default player for playing mpegs (or other video formats):
- System -> Administration-> Advanced -> File Associations -> video -> mpeg -> Applications Preference order -> Add...
- then choose your favourite media player. You can do this for a host of video file formats, including .wmv (x-ms-wmv, or Microsoft WMV format), .flv (x-flv, or Flash video), quicktime, and so on.
- To assign .pls audio streams to play through Audacious:

Run a KDE desktop from Ubuntu
It is possible to install the KDE-based desktop (the default in Kubuntu) in Ubuntu.
apt-get install kubuntu-desktop
There is a risk of software bloat and some incompatibilities between modules when doing this. At login, you can choose (as an option) whether to start the KDE (Kubuntu) desktop or the Gnome (Ubuntu) desktop. Nevertheless, when there are two modules trying to perform the same function (one from each desktop), it is possible to have conflicts.
Kill (end) a process
There are many tricks to try to fix a frozen PC. Press Alt+F2, and use killall to end the frozen application. Example:
killall amarok killall firefox
Another trick to try is pressing AltGr+SysRq+K (RightAlt+PrintScreen+K). This will log you out. But, what happens if this does not work? Try pressing Ctrl+Alt+F1,login, enter your password and run:
sudo killall gdm sudo startx
In the Nautilus file manager, press:
Ctrl+ H
Alien
Alien is a method for converting (Red Hat) .rpm packages into (Debian) .deb packages. It is not reliable and converted packages must be tested extensively for functionality, with line changes often required. It is often more reliable to create (Debian) .deb packages from source, and even the Alien software maintainers do not recommend using Alien for important packages. To keep alien from changing the version number, use the following command
alien -k rpm_file_name.rpm
Convert the package.rpm into a package.deb
alien -d package-name.rpm
Convert the package.rpm into a package.deb, and install the generated package
alien -i package-name.rpm
To convert .rpm to debian
sudo alien -k *.rpm
Software Troubleshooting
Permissions error on program startup
If you get a permissions error, try the following:
sudo chown -R user /home/user
- Note: Replace user with the actual username. This command changes the owner of the folder /home/user to user. -R means "recursively", i.e. including all subfolders.
CD-ROM Troubleshooting
If you receive the "cdrecord has no permission to open the device" error while burning using a CD burner, open a terminal and type:
sudo chmod 777 /dev/scd0
- Note: replace "/dev/scd0" with your own device.
- Note: chmod 777 is the universal option for granting full permission to a folder. The 777 mask indicates that read, write, and execute permission is given to all users.
Licenses
Linux is largely a community of volunteers and as such represents one of the largest altruistic efforts on earth. This includes companies who decide to contribute their own software into the public domain for free use. The continued success of sharing depends on licenses that keep software free and usable for anyone who wants to use it. However, there must be a method for Linux users and developers to make money, as well. Licensing helps protect each of these efforts. See the Wikipedia Free Software Licensing article and the GNU operating system licensing page for more complete information.
GPL license
The GPLv3 license intends that the software module or package is free to use in any environment, and furthermore, any software that relies on that GPLv3-licensed module must in turn also be completely free. Commercial and proprietary software packages can't use or incorporate GPLv3-licensed modules.
LGPL license
The Lesser GPL license intends that the software module or package is free to use in any environment, including in commercial and proprietary software packages. This allows companies to develop proprietary packages which includes LGPL-licensed modules, from which they can make a profit. The disadvantage is that their products (which benefit from the LGPL-licensed modules) are not required to be in the public domain in turn. (Many companies often later donate their entire package into the public domain, however, after they no longer make a profit from them.)
Proprietary licenses
There is a vast array of proprietary licenses, all different. You never know what your limitations for software are unless you read every word. Most are attempts by lawyers to have an opportunity to create a lawsuit in the future. Some may be called "free" licenses but have many limitations which you will not be aware of until you are in the middle of a lawsuit. No license outside of the GPLv3 license is recommended. Be careful when committing your organization to a mission-critical software package with a proprietary license. Also see this outstanding article on the Open Source Enterprise Trap.

Remove mplayer mozilla-mplayer for firefox and instead replace with gecko-mediaplayer plugin. gecko-mediaplayer plugin doesn't cause browser to crash and has less problems than mplayer-plugin.
