This is an old revision of the document!
In this page I am trying to collect all the issues that I solved from time to time, so that I remember how to fix those if needed.
The above picture belongs to this blog you might want to have a read: http://mschlander.wordpress.com/2011/01/23/kde-is-slow-for-dummies/
In systems running nvidia graphical cards, sometimes the video driver gets messed up with cached info. To fix this, run the following as normal user while logged in e.g. KDE:
nvidia-settings -a PixmapCache=0
Affected systems so far:
root@jarjar 11.4 ~> lspci | grep VGA 01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 8400 GS] (rev a1)
You can spot this if you login to a terminal and run
top. You'll see processes that contain
akonadi in the name taking over 100% of all cores and memory.
To solve this problem, - Login on terminal or ssh to any machine with your user. - cd into your home folder, and run the following:
rm -rf .local/share/akonadi rm -rf .config/akonadi rm .kde4/share/config/akonadi*
- logout and try to login graphically. Akonadi should not freak out anymore.
Due to incompatibility trough versions on nfs4, if in the logs such an error appears:
Jun 12 13:57:55 balder automount: umount_autofs_indirect: ask umount returned busy /nfs
then it seemed more stable to switch to nfs3. This is done in '/etc/nfsmount.conf'. Please ask the administrator for such a fix.
