I kind of had this problem and found that it was my screen size. I had set it too high. I found this out in Xorg log files.

I am having difficulties running applications that use the GLU library with fglrx-8.8.25 w/ hardware acceleration on X.Org 6.8.2 and SuSE 9.2 on an ATI Radeon 9600XT. Whenever I run an application that uses the GLU library the display will freeze and refuse to take any input from the mouse or keyboard; after this, the machine cannot be restarted without hitting the reset button (I have tried to ssh into the machine, su - and reboot). My running theory is that only some of the symbols in the GLU library are culprit as the application does not freeze at startup, but shortly thereafter (ie, blender runs fine until a menu is pressed; glxinfo runs with no problems).
I have the same ATI card and SuSE configuration except with an Athlon x86_64 board and chip. I also have a problem with occasional frozen screens since I installed the fglrx-8.8.25 driver. Interestingly my mouse cursor will still move from side to side but nothing works and I end up resetting. I've been unable to find any specific cause except that it only occurs during periods of activity. If I find out anything else I'll let you know.
