LinuxQuestions.org - vertical syncronization problem

Hi,

My System:

openSuSE 10.3
Nvidia proprietary drivers
compiz/xgl

When I drag windows, or when I play movies, there is always page tearing (windows seem cut in half).

I have __GL_SYNC_TO_VBLANK=1 set as environment variable, and the following is my xorg.conf, yet problem still not solved:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
