Public bug reported:
Thinkpad X220 with docking bay with external display attached to it.
I frequently dock and undock my laptop while it's on.
Since about thursday (I think) the desktop becomes completely unusable
when I dock or undock. The screen visibly corrupts, for example when
undocking (and going from 1x1080p external screen to 1x768 internal
panel) or docking. It flickers madly as if it's trying to crowbar
1920x1080 pixels into 1366x768 panel. Switching to VT and suspend/resume
doesn't fix it.
