With the fglrx driver on my laptop using Kubuntu, I have to turn off screen blanking, because every once in a while it causes my system to hang when the screen blanks. I am able to reset gracefully using ALT+PrintScrn+REISUB. I wonder if this is related to the same fglrx bug. I will try running my desktop without OpenGL compositing and see if that makes a difference.
