- 建个新用户看看，如果没问题，那估计是配置文件的原因了，配置文件在 ~/.kde 或者 ~/.kde4。然后你可以：
- Rename the file causing the problem. To find an appropriate file, look in ~/.kde/share/apps/application-name or in ~/.kde/share/config/application-namerc where application-name is the name of the application you are having problems with. The config file is the most likely problem.
- Log out, then log in afresh. New default files will replace your renamed ones.
- Clean out /tmp and /var/tmp. KDE stores some temporary files which can sometimes cause problems. You will need to be root to do this. You might also like to try removing the following files. Make sure you exit KDE first though! (The easiest safe way is to choose Failsafe at bootup.):
- ~/.kde/tmp-hostname which is normally a symlink to the next file:
- ~/.kde/socket-hostname which is also normally a symlink to:
- If you're running an old release from KDE, try updating to the latest version - many bugs are fixed with each new version, so your problem might already be fixed.
- Try searching the Bugzilla. Many common problems have been reported and discussed there.
- If your problem is more general than just one KDE application (e.g., "sound stops working when I start my KDE desktop"), try starting X with a different window manager. Even if you haven't installed another WM, 'twm' will be available, as it ships by default with X.
- If you start X with the 'startx' command, just put the appropriate command in the file .xinitrc in your home directory. (If it doesn't exist, create it)
- If you start your desktop from kdm, this will not work.
- Solutions you can try if your PC boots to an empty black screen
