I don't know if it's helpful to use the following command
I also have some problems with ati drivers. When I use the following command
sudo aticonfig --initial -f
which is a test for ati drivers it return 2, which means that I have a problem with rendering. This is sth that I realised when trying to view videos using vlc or mplayer. I believe that there sth to do with the ati configuration... Does anyone know sth better? Using the following commands I messed up my desktop effects but I fixed video
sudo atiode -P 10 -H localhost:0; echo$?
Is there sth to do to fix both my problems?
sudo aticonfig --sync-vsync=on
sudo aticonfig --xinerama=on
