OpenGL program freezes RH 9.0


My openGL programs compile fine but the system freezes when I execute them. I am forced to restart the computer. However, when I execute the same programs at a different Linux workstation, they work great.

Please give me suggestion on what the problem could be? The kernel is 2.4.20-8 with a Radeon 9000 Pro video card. I am not sure if its the video card or the openGL libraries that cause this problem.

You didn't give us much to go on, so I don't know how much it could be narrowed down. Which distro are you using, do you have the latest drivers? Which OpenGL apps?

BTW, your system should not require a reboot simply because one of your programs stops responding. Can you switch to a terminal and kill the programs process?

Bascially some texture mapping and ray tracing for my course work. Infact one of the programs executed once but the output colors were very poor. The distribution is RH 9.0. I don't know if the drivers are latest but RH recognized my video card and enabled 3D acceleration.

Yeah ... I completely forgot about switching terminal and killing the process. Thanks for that.

Thanks!

If RedHat auto-installed the card then I would say this is most likely a driver issue. Some people have reported problems with the Radeon family of cards. RedHat 9.0 does have an OK set of Radeon drivers included, but I bet upgrading to ATI drivers would solve your issue.

PS, This seems to be a hardware issue more than anything, hence the reason I replied to your post here, and not in the other forums you posted this question in.

Have you used the top command, or run something like GKrellm to show you maybe a huge increase in cpu usage as your processor renders the graphics and not your card?

You might want to be sure that this is not causing your problems. It seems to affect quake based games...

The bug and workaround is reported here....

FireGL drivers version 2.9.12, r_ext_compiled_vertex_array 1 (the default) can cause application hitching and freezing under heavy geometry load. You should run with +set r_ext_compiled_vertex_array 0.
,This mentions XFree4.3 but I have noticed this behaviour under Xfree4.2 w/ the 2.5.1 drivers from ATI it's infrequent though

The problem was with the driver. I upgraded it and everything worked magically!
