i use a RedHat 9 box with an Nvidia graphic board and i am using Nvidia's driver to obtain graphic 3d acceleration.I would imagine that you have a problem with a solution different to that described in the NVidia docs. On my machine, ls -l /dev/nvidia* gives
Currently VTK/opengl complains about permissions on /dev/nvidiactl
crw------- 1 jch root 195, 0 Oct 29 13:01 /dev/nvidia0 crw------- 1 jch root 195, 1 Oct 29 13:01 /dev/nvidia1 crw------- 1 jch root 195, 2 Oct 29 13:01 /dev/nvidia2 crw------- 1 jch root 195, 3 Oct 29 13:01 /dev/nvidia3 crw------- 1 jch root 195, 4 Oct 29 13:01 /dev/nvidia4 crw------- 1 jch root 195, 5 Oct 29 13:01 /dev/nvidia5 crw------- 1 jch root 195, 6 Oct 29 13:01 /dev/nvidia6 crw------- 1 jch root 195, 7 Oct 29 13:01 /dev/nvidia7 crw------- 1 jch root 195, 255 Oct 29 13:01 /dev/nvidiactl
Which is what I would expect. If I look in /etc/security/console.perms I see
<dri>=/dev/nvidia* /dev/3dfx* and <xconsole> 0600 <dri> 0600 root
It's hard to guess what has gone wrong, but I expect that something has :-) Do you have two X servers on different virtual consoles? That can probably cause problems. Has your /etc/security/console.perms files got corrupted? I've had problems when logged into a virtual terminal as one user and then logging into X as another: that shouldn't apply in this case, but it's somethng to look into.
I'm certainly not going to flame you for using the NVidia drivers -- most of my machines have NVidia cards of one sort or another and I run the NVidia drivers in all of them. Admitedly, mostly for the sake of the snazzy OpenGL screensavers :-)
