[Bug 969860] Re: fglrx uses 100% CPU when screen turns off (spinning in glXWaitVideoSyncSGI or glXSwapBuffers)

 

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.
