Okay, I checked Skype, vlc and Zattoo, but I didn't recognized, that after purging and reinstalling xserver, I also purged my config. So it didn't use nvidia. Then I called nvidia-xconfig and now, I have the same Issue :-(

The wierdest is, that skype runs until i click into its window. Actually I don't know what the links have to be like but since I reinstalled everything, they should be fine now. What else could be responsible for my troubles?

Here are some ls, just to check them:

ls -lR /usr/lib/nvidia/
/usr/lib/nvidia/:
drwxr-xr-x 2 root root    4096  9. Mai 20:16 diversions
lrwxrwxrwx 1 root root      18  3. Mai 00:42 libGL.so.1 -> libGL.so.270.41.06
-rw-r--r-- 1 root root  781540 19. Apr 00:11 libGL.so.270.41.06

ls -lR /etc/alternatives/libGL.so*
lrwxrwxrwx 1 root root 35  9. Mai 20:17 /etc/alternatives/libGL.so -> /usr/lib/nvidia/diversions/libGL.so
lrwxrwxrwx 1 root root 26  9. Mai 20:17 /etc/alternatives/libGL.so.1 -> /usr/lib/nvidia/libGL.so.1

Could this be a qt related problem, since it only occurs with qt apps?

Thanks for advice
