Description Nils Kanning 2008-02-22 07:52:22 UTC 
After closing the lid of a Thinkpad T60 (2007-49G, bios 79ETE0WW, Radeon x1300, 1400x1050 panel) and opening it again the resolution of the screen is very low and just the upper left corner fits on the lcd-panel. Furthermore the image is corrupted - there are white horizontal stripes.
Switching to a console and back to the x-server fixes this issue.

My Xorg.log files after the relevant steps ("before_closing_lid", "opened_again_console", "opened_again_x") are attached.

I am using the xorg 7.3 from Debian unstable and the git version of the graphics driver (xf86-video-ati).

If there is anyway the acpi driver for your laptop can disable the video bios routine that gets called when you hit the lid button that would help.  There is also a way to stop the bios from touching the hw on lid events via the bios scratch regs.  I attempted to implement support for this, but I don't have an atom based laptop, so apparently it doesn't work yet.  Let me see if I can sort out some patches for you to try.

this should be fixed in 6.9.0.
