UT2003 and GL screen saver won't run.

My OS is RedHat9(xserver 4.3.0). My graphics card is a Radeon 9500Pro using the latest ATI Linux driver for 4.3.0. I get the following when I try to play UT2003.

[niverson@landshark ut2003]$ ./ut2003
open /dev/dsp: Device or resource busy
Xlib: extension “GLX” missing on display “:0.0”.
Xlib: extension “GLX” missing on display “:0.0”.
Couldn’t set video mode: Couldn’t find matching GLX visual


Exiting due to error

I change the xserver graphics modes to see if UT2003 could find a matching GLX visual, but no luck. Also the screen saver marked with GL(I’m guessing that is for openGL), don’t run. The none-GL screensavers run fine.

Does anyone have some insight?


I run Redhat 9.0 as well but I use an Nvidia FX 5600 Ultra myself. It seems like GLX is not being loaded up for you and thus you dont have any OpenGL support in XWindows. I’m not sure on the implementation of the ATI drivers, but for Nvidia Linux drivers take a look at your /etc/X11/XF86Config file and make sure under the module section you have, Load “glx”. And I believe Load “dri” and Load “GLcore” are not supposed to be present when you have hardware OpenGL support.

Other than that, check the ATI readme for their linux drivers, sounds like a step might of been overlooked.
