[Bug 30447] Re: Lockup problems with both the free xorg ATI driver and the proprietary fglrx driver, using various ATI cards

[Steven Bell]

I had a similar problem with drivers 8.24 through 8.27.  Roughly one in three logouts, the screen would turn completely white.  At that point, Ctrl-Alt-Backspace crashed the computer.  After commenting out in xorg.conf:
	#Option	    "VideoOverlay" "on"
	#Option	    "OpenGLOverlay" "off"
it seems to work fine. :-)
