Description Yuri 2012-04-20 01:23:33 UTC

I have a fresh Ubuntu 11.10-desktop i386 installation from CD + updates from internet on IBM ThinkPad R51 laptop.

OS works, but after I close the laptop cover and it falls asleep, and I open the cover, it comes back with the black screen.
I can see that OS itself did wake up, I can type password to come back into the workspace (I can see this from the cursor changes). But screen itself stays completely black.

Killing X (Xorg) process from the black terminal doesn't help. X comes back with the black screen again.

"Radeon Mobility 9000 (M9) Lf (AGP)", ChipID=0x4c66

I filed Ubuntu PR: https://bugs.launchpad.net/ubuntu/+bug/986045 , but it seems that Xorg is most likely a culprit.

xorg-7.6+7ubuntu7
