I bought a gainward 6800ultra and installed the NVIDIA-Linux-x86-1.0-6111 driver.
When i start a game like et or quake 3 the xserver frezees sometimes.
I saw only a black screen and couldnt do anything.(Strg+Alt+F1,2,3...)
The system has worked fine with a ti4400.
Debian Sid, Linux 2.6.7, 475W powerpack
Dont know if its the right log file .
(Sorry for my bad english
