devtry1, don't worry, you're not the only one with this problem. Given your extended description of the issue in comment #39, I would say Chris was right merging these two bug reports. I have sporadically seen what appears to be the same problem, only with KDE. The GPU will hung, the timer will time out and usually manage to reset the chip. In the process, however, the compositing window manager dies, so you no longer have control over window positions, desktop shortcuts, etc. For me the solution is generally to reboot, because even if I can successfully restart the X server, the GPU is in an ill-defined state so 3D acceleration doesn't work properly. I have not been able to find a reliable way of reproducing it; sometimes it "just happens", luckily, not very frequently.
