Installation
Prerequisites:
Before you begin you will need the following:
- A USB drive
- A downloaded image (iso) of the Ubuntu Intrepid installation CD (not required for UNETBOOTIN method)
Before you begin you will need to know the following:
Creating USB startup disk:
Method 1: (From an Ubuntu Intrepid computer, or computer running Ubuntu Intrepid Live CD) UBUNTU USB TOOL
Go to System -> Administration and select Create a USB startup disk. Select the Ubuntu image and the USB device, then press the Make startup disk button at the bottom of the window. (Either of the options at the bottom of the window, regarding saving documents and settings, will work with this method, so pick your preference.) After it is finished, [[UbuntuHelp:[install|install from the USB startup disk]]]
Method 2: (From any Windows or Linux Computer) UNETBOOTIN
Download Unetbootin to your computer and plug in your USB drive. Follow the instructions at the UNetbootin website to create a USB startup disk. When the startup disk is ready, [[UbuntuHelp:[install|install from the USB startup disk]]] <<Anchor(install)>>
Installing to NC10 from the USB startup disk:
Plug in your USB startup disk, then reboot the computer. You may need to change your NC10's boot settings so that it will boot from a plugged-in USB disk; to check, press F2 when the Netbook is first turning on to enter BIOS setup. When you have verified this, save changes and exit BIOS setup. The computer should then boot from the USB startup disk, offering you an Ubuntu menu. Select Install Ubuntu to begin installation.
Wireless Networking - Atheros
The wireless hardware is detected, but a non-functional driver is loaded when Ubuntu is installed. Installing the latest Madwifi driver resolves this problem. First, disable the installed driver from System->Administration->Hardware driver by clicking Deactivate on the bottom of the window. Next, blacklist the bad driver by adding it to your kernel blacklist. Open a terminal and enter (or use gedit to edit the blacklist file)
sudo su echo "blacklist ath_pci" >> /etc/modprobe.d/blacklist echo "blacklist ath_hal" >> /etc/modprobe.d/blacklist
Finally, install the Madwifi driver:
sudo apt-get install linux-backports-modules-intrepid sudo su echo "ath5k" >> /etc/modules
After rebooting the driver should load and wireless networks should be listed in the Network Manager Applet.
Audio - Alsa Driver
-- These directions work on kernel 2.6.27-7. However several attempts on 2.6.27-9 confirms that they disable all audio and then cannot be rolled back. Further testing needed. @carneades The Alsa audio driver needs to be recompiled since the on-board chipset is a Realtek ID 272 which is not fully supported by Ubuntu 8.10. When compiling the driver from source the package build-essential is needed. In terminal type:
sudo apt-get install build-essential libncurses-dev gettext xmlto xmltoman linux-headers-`uname -r`
The last Alsa Driver source can be downloaded at here (tested on v. 1.0.18a) Extract it on Desktop and in terminal type:
cd Desktop/alsa-driver-* ./configure --with-cards=hda-intel --with-oss=yes --with-sequencer=yes make sudo make install
Set the volume levels in alsamixer - In terminal type:
alsamixer
The internal mic can be made to work for playback and capture by adjusting the Volume Control settings for the Front Mic. To support recording, the Input Source (available by selecting Preferences in the Volume Control) needs to be set to "Front Mic". Restart the computer. The internal speakers will be disabled when you plug-in a headphone's jack.
Hotkeys
Bugged
For correctly mapping the FN key that are doesn't recognized by default, you have to substitute the file in /usr/share/hotkey-setup/samsung.hk with this lines
setkeycodes e006 238 # Wireless ON/OFF setkeycodes e008 225 # Brightness UP setkeycodes e009 224 # Brightness DOWN setkeycodes e002 $KEY_SWITCHVIDEOMODE # Monitor Switch setkeycodes e003 236 # Battery
ATTENTION There's a bug opened for this and it may give you some problem with keyboard hang. If you are interested on the solution visit lauchpad.
Fn Brightness Keys - Workaround
Currently it is impossible to map the FN keys. Therefore, two utilities for mapping alternative keys are needed so that screen brightness can be adjusted. From terminal:
sudo apt-get install xbacklight
Download Ubuntu Tweak from here and install it. Now open Ubuntu tweak (Application -> System tools) go to the appropriate section (Personal -> Shortcut) and set the combination that you want for example Ctrl+UP with:
xbacklight -inc 10
and Ctrl+DOWN
xbacklight -dec 10
To increase and decrease the screen's brightness Maximum brightness may be quite low if you don't disable the "auto" brightness feature in the BIOS (F2 at start-up).
More Fn Key Workarounds
It is possible to replace more of the non-functional Fn-* keys with Ctrl-* keys. A writeup is available here that needs testing.
Xorg (optional, work in progress)

Internal 3G modem
Some NC10 models are sold with built-in, internal SAMSUNG HSPA Modem. Such models are in particular available in Poland (they are sold with iPlus wireless internet service). This modem does not appear to work at all. The USB vendor:product id is unknown to google as of 3rd of December 2008. The modem is a USB device and is supported on Windows XP. It's therefore possible to sniff the USB communication and reverse-engineer the drivers for the open source community. The USB vendor:product id is: 04e8:6773 As the text below says, the modem probably works Inspired by the mini howto I went to debug why does network manager fail to find it. It turns out that ubuntu's patches to network manager are using AT+GCAP to see what the modem supports. After changing that to ATI the modem is immediately detected. Unfortunately I'm outside of poland ATM so I cannot check if my fixes work but it's very, very close to being 100% usable for regular users! Modem is visible in system as cdc_acm and works like a charm with gcom Mini how-to
sudo aptitude install gcom
I've made a rule for udev, becouse sometimes modem is ttyACM0 and another time ttyACM1
cd /etc/udev/rules.d
and add own rule in for example file named 99-own.rules
SUBSYSTEM=="tty", ATTRS{product}=="SAMSUNG HSPA Modem", SYMLINK+="modem"
after adding new rule you have to restart udev
sudo /etc/init.d/udev restart
sudo gcom
you'll have to insert your pin code next we need to configure connection. I've used wvdial and configuration from http://www.goldenline.pl/forum/linux-i-open-source/70382
sudo vim /etc/wvdial.conf (you can use your favorite editor) Add below lines: Modem = /dev/modem Baud = 460800 SetVolume = 0 Dial Command = ATDT FlowControl = NOFLOW Init1 = ATZ Init2 = ATM0 Auto DNS = 1 [Dialer iplus] Username = any Password = any Phone = *99***1# Stupid Mode = 1 Init3 = AT+CGDCONT=1,"IP","www.plusgsm.pl" Dial Attempts = 3
Second file should be placed in /etc/ppp/peers and named wvdial
plugin passwordfd.so # noauth name wvdial replacedefaultroute noipdefault nomagic usepeerdns ipcp-accept-local ipcp-accept-remote nomp noccp nopredictor1 novj novjccomp nobsdcomp
now you can try to connect
sudo wvdial iplus
I'm using debian sid, but this howto will probably work on ubuntu. If you have any questions email me at lolicjusz at gmail . com

Ubuntu Hardy Heron 8.04 on the Samsung NC10
Instead of installing Intrepid Ibex I wanted to install Hardy Heron on my Samsung. This is a reflection of my notes so far and thus a work in progress for now. It's not yet complete and needs more work. Only use it if you know what you're doing.
/!\ Edit conflict - other version: ----
Installation using Alternate installer for encryption
Since this is a highly mobile netbook I want my data to be save and thus I opted for full disk encryption. In order to do so I had to tweak the install with a USB stick a bit. Otherwise the Hardy Heron Alternate Installer would complain about a cdrom drive not being present.

Wireless Networking - Atheros
Make sure the wireless hardware is active. Afaik the blue light of the third led from the right should be lit. Double check your BIOS settings. Remove the installed driver. Go to System–>Administration–>Hardware Drivers and disable by un-ticking the following option Atheros Hardware Access Layer (Hal) Then Reboot your system. Go into the terminal and install the following:
sudo apt-get install build-essential subversion autoconf automake
Afther this remove any existing wifi mods afaik this should do it:
sudo modprobe -r ath_pci sudo modprobe -r ath_hal sudo modprobe -r wlan
To get the correct(according to this comment) madwifi driver I'm using Subversion. On the terminal issue the following command:
svn co http://svn.madwifi-project.org/madwifi/branches/madwifi-hal-0.10.5.6/ madwifi
Now enter the madwifi directory
cd madwifi
Compile
make
then
sudo make install-modules
Now we can install the modules into the kernel using the following
sudo modprobe ath_pci
Scan for some wireless networks
sudo iwpriv ath0 bgscan 0
You should now be able to use the wireless netwerk. NB: I used the following from the Macbook instructions so after a resume the network card should automatically start again. Not sure if this is necessary nor that it work correct. Need some more time to test.
echo -e '#!/bin/sh\n/sbin/iwpriv ath0 bgscan 0' | sudo tee -a /etc/acpi/resume.d/99-madwifi-bgscan.sh
And
sudo chmod 755 /etc/acpi/resume.d/99-madwifi-bgscan.sh
