Quake II only runs if I'm root

**xdenizen** · 09-02-2005

I'm running FC4 on an Atlhon 64 3500 with a gig of RAM and a GeForce 6200 (128 mb) graphics card.

For various reasons I had to uninstall and reinstall Quake II (I'm using the Loki native Linux version). Previously I could run Quake II as a normal user. Now I find I can only run the game if I have root privileges.

If I run Quake II as a mortal user I get the following response:

Code:

------- Loading ref_sdlgl.so -------
LoadLibrary&#40;"./ref_sdlgl.so"&#41;
rfx_gl version&#58; GL 0.01
Using libGL.so for OpenGL...setting mode 3&#58; 640 480
Xlib&#58;  extension "GLX" missing on display "&#58;0.0".
Xlib&#58;  extension "GLX" missing on display "&#58;0.0".
Cmd_RemoveCommand&#58; joy_advancedupdate not added
recursive shutdown
Error&#58; &#40;SDLGL&#41; SDL SetVideoMode failed&#58; Couldn't find matching GLX visual

But running it as root (su) presents no problems. Naturally I don't want to run anything as root if I don't have to. I have edited the /usr/local/games/quake2/quake2.sh to reflect the fact that I have an AMD Athlon 64 but it makes no difference. I should say that I have today installed the nvidia graphics card driver.

I'm sure there is a simple answer to this, I just can't work it out. Could it be that I need to change permissions on a file somewhere? Is it because I installled the nvidia drivers? Could the culprit be global warming?

Try to give users write privilege on your your video card device:

Code:

chmod 0777 /dev/dri/card0

This is a bit embarrassing.

I mean you wouldn't think I've been using linux since 1999. I can recompile the kernel but I cannot for the life of me work out what the name of my video card/driver is in the /dev directory.

I must have examined the /dev directory about eleventy squillion times but with no luck. Can anyone tell me what it might be called?

As I said above:

Kind regards,

Try lspci

That should give you an idea of which driver.

Hehehehe,

Well after making a small edit to my /etc/X11/xorg.conf file (or whatever the hell its name is) the sucker finally works! I can run Quake II as a mortal. That small edit was changing "vesa" to "nvidia".

Thanks to everyone who gave their advice. I am very grateful.
