Baris> video card: creative tnt2ultra 2X Baris> video driver: nvidia I'd try getting rid of the Nvidia module and making sure that X works just fine without it. Sure you won't have acceleration, but you're looking for stability first, right? I'd also check and see if you have the correct kernel version for the nvidia driver your using. Any messages in the logs? Look in /var/log/messages, and think about turning on more verbose X logging. I can't find the file(s) to tweak in a quick search though. John
