hi.. I have installed nvidia driver(onboard Geforce go 6150 graphics card). When I play movies and other videos with compiz or beryl disabled everything works fine and never display freezes. But when I enable compiz/beryl, only Xorg consumes about 70% processor and hangs for a while. When I play videos the audio continues in the background and display freezes completely except movement of mouse cursor. Sometimes with video not running also the display freezes. I just cannot keep compiz/beryl enabled. Can anyone please tell me what is the problem? Or is it a problem with nvidia driver itself? thanks in advance for your help. I am Fedora core 6 user. -- manu
