If you think problem's link could be improved or could have a better link, please propose the change in [http://ubuntuforums.org/showthread.php?t=452538 this Ubuntu Forums thread] for further discussion. == Initial Setup == *'''Problem''': The Ubuntu CD freezes in the middle of installation '''Solution''': The CD image was probably corrupted during download or burn, or you do not have enough RAM (less than 256 MB) to run the Desktop CD. [http://www.psychocats.net/ubuntu/iso These instructions] will help you get an intact (uncorrupted) CD. If you don't have enough RAM, [http://users.bigpond.net.au/hermanzone use the Alternate CD] *[http://users.bigpond.net.au/hermanzone/SuperGrubDiskPage.html#Common_Booting_Errors_and_Some_Possible Fixes for common booting errors] *[http://www.psychocats.net/ubuntu/nox If you're stuck at the command prompt after installation] == Partitions == *'''Problem''': I can't create or delete or modify a partition using Gnome Parted Editor (GParted) '''or''' I have problems creating or deleting or altering my partitions using GParted on the Ubuntu Live CD. '''or''' the Ubuntu Live CD keeps auto-mounting my partitions, thus deleting a partition via GParted on Live CD has no effect. '''Solution''': Download a partitioning dedicated LiveCD such as the GParted Live CD or the Parted Magic LiveCD and boot from it. You should have no problems modifying, deleting, or creating partitions using the LiveCd. GParted Live CD can be found at http://gparted.sourceforge.net/.

Now, when an application or window is open, it doesn't have an icon on the taskbar or the close, maximise and minimise buttons in all my application and windows are gone, or have changed position on the menu bar! '''Answer:''' This is one of many possible solutions. Try pasting the following command into [https://help.ubuntu.com/community/UsingTheTerminal#head-2fa31364ee2acb07982a2fd5f52c983130565f8f the terminal] <pre><nowiki>sudo dpkg --configure -a </nowiki></pre> There is a possibility that Gnome might have crashed while updating gnome-panel. After the updates or softwares have finished installing, press Alt-Ctrl-Backspace to restart X or simply restart the computer. Gnome should be functioning properly now. === Email === *[http://ubuntuforums.org/showthread.php?p=321569#post321569 Clicking on links in Thunderbird won't open Firefox] === Web browser === *[http://ubuntuforums.org/showthread.php?t=255422 HowTo: Fix Firefox Flash Sound Issues] *[http://ubuntuforums.org/showthread.php?p=2612806#post2612806 Firefox won't open new windows as tabs] *[http://kb.mozillazine.org/Profile_in_use#How_to_unlock_your_profile Firefox is already running error message] *[http://ubuntuforums.org/showthread.php?p=1692197#post1692197 Flash makes Firefox crash] === Sound === *[http://ubuntuforums.org/showthread.php?t=452957 How do I find libmp3lame.so in Audacity?] == User Permissions == *[http://www.psychocats.net/ubuntu/sudo I lost the ability to sudo] *[http://ubuntuforums.org/showthread.php?p=2619991#post2619991 $HOME/.dmrc file is being ignored when logging in] *[http://ubuntuforums.org/showthread.php?p=2654159#post2654159 I don't have permission to write to the desktop] == File Issues == *[http://linux.sys-con.com/read/117909.htm Can I recover deleted files on an Ext3 drive?] == Upgrade Problems == *[http://ubuntuforums.org/showthread.php?p=2565564#post2565564 Virtual terminals don't appear after an upgrade to Feisty Fawn] ---- [[category:CategoryDocumentation]] [[category:UbuntuHelp]]
