I can't get Wolfenstein ET to run on my Slackware 10 box. I have a Matrox G400 32mb video card. I am using Xorg 6.7 and the included mga drivers. I have my monitor set at 1024x768 @ 85 and 24bit color. When I run et I get the error below. What do I need to change?

Made a new kernel, still nothing. I guess I should try the drivers from the matrox website. Should I buy a cheap NVIDIA card?

Does anyone have a clue to what I should do?

I bought a NVIDIA GeForce TI 4200 for $85, hope this fixes the problem.

Hello,

I'm coming to this forum from a Google search. I ended up finding my own answer, which I thought I'd share here for any who may still be having this problem. For reference (and other's search parameters), I'm trying to run Neverwinter Nights Linux version on a Slack 8.1 install, with a Matrox G450 video card. I used the ravage installer (found on icculus.org) and am trying to resolve an OpenGL issue.

Each time I tried to run the game, I'd get two lines back that would say:

libGL error: failed to open DRM: Operation not permitted
libGL error: reverting to (slow) indirect rendering

I tried running /usr/X11R6/bin/glxgears to test this issue. It turns out that I didn't have permissions to the video card when trying to run OpenGL. This is found at /dev/dri/card0 on my system (I can't speak to other systems and distros).

Long story short, I had to (as root) "chmod 755 /dev/dri " _and_ I had to "chmod 777 /dev/dri/card0". BUT here's the tricky part. These permissions appear to change. I was testing in X (so I could browse the web for help) and everything was fine. (And I do mean _FINE_! It was running so smoothly!) Then, I quit X and started the X server with no window manager (how I play all my video-intense games) and I'm back to slow and crappy.

Lo and behold, the permissions have changed again. At this point, I suspect I'll just have to remember to check permissions each time I want to play the game. Maybe I'll do some research as to _why_ this happens and how I can preserve my privileges at a later date. (Or would some Linux guru like to point me to the right place for reading?)

Anne.

Hi,

permissions should be set by the udevd. in my case (gentoo linux) they were set in /etc/udev/permissions.d/..

Hope this will help you

EDIT: adding the user to the video (or eq.) group seems to be the best solution.

Yeah thnanx guys. It helped me a lot
