On a stock Dell, RHEL 5.3, my X gets stuck when running any OpenGL program for more than a few seconds. After a few seconds, the screen freezes, and after another few seconds sometimes the screen turns white.
Any openGL program does that. I wrote a very simple program that uses only very basic polygon drawing, and it still causes X to freeze.
Killing X won't help it recover.
dmesg and the X log don't show any special errors except of
(WW) AIGLX 3D driver claims not to support visual 0x23 (WW) AIGLX 3D driver claims not to support visual 0x24 ... (WW) AIGLX 3D driver claims not to support visual 0x32
Similar error message appears after I execute an glut OpenGL program.
What could be the trouble? How can I further debug the issue?
