Bug#600273: xserver-xorg-video-radeon: Black screen after resume from suspend-to-disk

[intrigeri@boum.org]

Package: xserver-xorg-video-radeon
Version: 1:6.13.1-2
Severity: normal

(This is related to #565344 that was closed because of too many
issues inside a single report.)

I sometimes get nothing but a mouse cursor and a black screen when I
resume the machine from suspend to disk. This happens quite rarely,
but when it does it is pretty annoying.

Workaround: blindly unlock gnome-screensaver, and run the following
command in a terminal :

	xgamma -gamma 1.0              

hardware: Thinkpad X32 (Radeon Mobility M6 LY)

KMS disabled (as hibernation is broken on my hardware with KMS
enabled)

linux-image-2.6.32-5-686 2.6.32-23
window manager: xmonad
gnome-screensaver is running
