-====== Problems @ Matfys ====== +remove ​this page.
- +
-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. +
- +
-===== Very slow graphical interface on workstation ====== +
- +
-==== Disable Desktop Effects in KDE ==== +
- +
-- Click on the KDE icon and search for ''​Desktop Effects''​ +
-- Disable effects as in this picture: +
-{{http://​mschlander.files.wordpress.com/​2011/​01/​effects.png?​w=720}} +

-The above picture belongs to this blog you might want to have a read: +

- +
-==== NVIDIA video card issues ==== +
- +
-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: +
-<code bash> +
-nvidia-settings -a PixmapCache=0 +
-</​code>​ +
- +
-Affected systems so far: +
-<code bash> +
-root@jarjar 11.4 ~> lspci | grep VGA +
-01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 8400 GS] (rev a1) +
-</​code>​ +
- +
-===== System becomes unresponsive and crashes ===== +
- +
-==== Akonadi+nepomuk eating all CPU power and memory ==== +
- +
-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:<​code bash> +
-   rm -rf .local/​share/​akonadi +
-   rm -rf .config/​akonadi +
-   rm .kde4/​share/​config/​akonadi* +
-</​code>​ +
-- logout and try to login graphically. Akonadi should not freak out +
-anymore.+
