Troubleshooting

Plasma Crashes

In case your desktop (or plasma crashes), use the following commands to kill and restart plasma:

kbuildsycoca4
kquitapp plasma-desktop
kstart plasma-desktop 
    
Plasma Configuration Files

If you ever need to manually modify the Plasma configuration files, find them in your system under ~/.kde4/share/config/plasmarc and ~/.kde4/share/config/plasma-appletsrc. The first one stores global settings like the desktop theme, while the latter stores the settings for all the individual applets.
