[Bug 532517] [NEW] External monitor goes black

 

Public bug reported:

Binary package hint: xserver-xorg-video-ati

Every so often using Karmic, external monitor screen (mirrored to laptop screen) goes blank while laptop screen displays OK. I think that this may be happening when I move the mouse after a few seconds inactivity on my part. One thought is that the following part of the Screen Section (in xorg.conf) should not be commented out:
	#	SubSection "Display"
	#		Virtual	2048 2048
	#	EndSubSection
I have the feeling that this was commented out  when I was using Jaunty due to external screen mode display problem.
