I am seeing the same bug in precise, kernel 3.2.0-44-generic. I have a AMD HD7850 graphics card, on a desktop machine. After rersume from hibernate the screen is corrupted, similar to previous discriptions. I press CTRL + ALT + F1, to fall back to a console then login. There is no corrution in the console. I then use command: sudo top. I kill xorg with top. Immediately xorg restarts and a normal graphical uncorruted login screen appears. From there I login to unity and everything works fine but this bug needs to be fixed because there is no way to resume to a previous desktop state. My graphics driver is: amd-catalyst-13.4-linux-x86.x86_64 proprietary download and install from the AMD site. xorg version: 1:7.6+12ubuntu2 xserver-xorg-core: version 2:1.11.4-0ubuntu10.13 xserver-xorg-video-s3: version 1:0.6.3-4build2 xserver-xorg-input-all: version 1:7.6+12ubuntu2 xserver-xorg-video-all: version 1:7.6+12ubuntu2 libx11-data: version 2:1.4.99.1-0ubuntu2.1 python-xkit: version 0.4.2.3build1

Upon entering S4, the graphics become corrupt - it looks a bit like an X11 stipple or that checkerboard that used to be the X background (though it's not just B&W, there is some R/G/B in the pattern. The pattern is not as random as static; it appears tiled, as if we're displaying tiles populated with corrupt video memory. On resume from hibernate, the BIOS logo is not corrupt and the (not- corrupted) plymouth logo flashes for an instant. There are several seconds of a flashing white cursor at the top left of the screen too. Once X comes back I see the stipple pattern/corruption again. Both the X and console sessions are corrupted. There is a separate corrupt tile surrounding the mouse cursor (the cursor itself is not visible). Moving the mouse cursor results in the mouse-tile moving around. The machine is otherwise functional - I can (blindly) login to a console on a VT and execute commands. Syslog from the failed resume session shows errors from drm:radeon, starting with: Dec 19 14:36:49 ubuntu-ThinkPad-SL510 kernel: [ 1026.671568] [drm:r600_ring_test] *ERROR* radeon: ring test failed (scratch(0x8504)=0xCAFEDEAD) Dec 19 14:36:49 ubuntu-ThinkPad-SL510 kernel: [ 1026.671570] [drm:rv770_resume] *ERROR* r600 startup failed on resume If I disable the radeon driver by adding, e.g., the made-up 'radeon.nofailboat=1' kernel parameter, the machine enters and resumes from S4 normally, with no corruption upon either entering or resuming from S4. I've reproduced in both the stock 10.10 kernel and the daily natty kernel (2.6.37-999-generic #201012200905).
