Comment 5 for bug 669779

Hoping to re-animate this bug and maybe see it fixed. Running 11.10 on a ThinkPad X40 with the Ultrabase X4, I have the same initial symptoms as OP: drops to a console with graphical corruption along the top edge of the screen that looks like what happens when you dump non-video data straight to the framebuffer, and the machine is unresponsive.

HOWEVER, I can enter virtual console with Ctrl-Alt-F1, and then switch back to the X console with Ctrl-Alt-F7 and pick up right where I left off. I've tried adding a script to run on undock that should force the machine to continue using Thinkpad-LVDS (can't remember the precise device name) to no avail.
