How to restore a known working Ubuntu KDE/Gnome GUI setup.
Any CS public lab with thin clients can access the teaching Linux systems. These labs are in MC 2061, and 3022.
You will want to check that you have account quota prior to doing the re-initialization
step below as that may be explain login difficulties. You can do this by typing
diskquota
while logged into the Solaris environment.
.gnome2
, .gnome2_private
, .gconf
and .gconfd
. You can either move
them aside by creating a temporary directory in your home directory and then
move them into that temporary directory (use the mv
command) or simply delete
them by doing
rm -rf .gnome2 .gnome2_private .gconf .gconfd
.kderc
and the directories
.kde
and .qt
. To remove these execute the following command while located
in your home directory
rm -rf .kde .qt .kderc
Next test to see if you can login succesfully by choosing the Gnome or KDE Session from the login window.
From another account, or the 'failsafe' window manager (see below), check your
quota and ensure you're below it. A prime candidate for quota bloat is Firefox
disk cache. Firefox cache is set to 0 on mef-fe systems, but firefox doesn't
delete cache already on the disk. To wipe the disk cache, delete the contents
of: ~/.mozilla/firefox/*.default/Cache
.xsession
file.
From another account, check for a .xsession-errors
file in your home directory. If it contains lines like
/u/userid/.xsession: 12: /software/x11-mfcfenv/data/xdm/xsession: not foundtry moving your .xsession file aside (
mv .xsession .xsession.old
) and then logging in.
echo .mozilla/firefox/*.default/bookmarks.*It should give you the file pathname. Make sure firefox is not running while you are re-initializing it.
Window managers can be chosen on the login screen, at any time before submitting the password. At the top-left side there is a menu, "Session". There are choices for KDE, Gnome, Failsafe Gnome, and Failsafe Terminal.
The user will be asked to confirm whether they want to use the non-default window-manager. They can chose to use the non-default window manager for one session, or all future sessions.
KDE can be customized by running 'kcontrol' from the command-line. Some customizations can be made by editing configurations in $USER/.kde .
Gnome can be customized by selecting the "System" menu from the top bar, sub-menu "Preferences".
The user's home directory is shared across the entire student.cs region. Some students may already have KDE/Gnome configurations on other Linux servers in cs; such as in the TrashCFGraphicsLab.
