Hi, Following a reboot/powerup before starting doom3 or unreal; I have to modify the permissions on the following files: ================================================================ [root@lion ~]# ls -l /dev/nvid* crw-rw-rw- 1 root root 195, 255 Jan 15 23:41 /dev/nvidia crw-rw-rw- 1 root root 195, 0 Nov 7 19:05 /dev/nvidia0 crw-rw-rw- 1 root root 195, 255 Nov 7 19:05 /dev/nvidiactl ================================================================ Does anyone know the trick to make this stick? Following a reboot I must execute: chmod o+rw /dev/nvid* I am using "NVIDIA-Linux-x86-1.0-6629-pkg1.run" Thanks, Ernesto
