Bug#565344: [xserver-xorg-video-radeon] Black screen after resume from suspend to disk/RAM

[Johann Glaser <glaser@ict.tuwien.ac.at>]

Hi!

I had the same problem here, except that at my laptop with dual screen
setup only the external screen kept blank after wakeup from suspend to
disk/RAM. Executing "xgamma -gamma 1.0" perfectly restored its output.

Some details:
 - ASUS M6V Laptop
 - ATI Technologies Inc M24 1P [Radeon Mobility X600] rev 0
 - "radeon" driver
 - LCD mounted to the laptop worked after wakeup, but external
   (connected with VGA) didn't
 - Debian sid, last updated on 2010-02-05
 - xserver-xorg-video-radeon 1:6.12.4-3
 - xscreensaver, xscreensaver-data, xscreensaver-gl 5.10-7
 - gnome-screensaver 2.28.0-2
 - xscreensaver-gnome 4.21-4

Bye
  Hansi
