Just hit this bug with my thinkpad X201 (Arrandale core i7 M620) after the following sequence: xrandr --output HDMI1 --off (its actually a DVI display using a DP->DVI cable from the docking station) undock suspend get home, unsuspend Notice that xrandr still thinks I have a 3200 pixel wide display (1920 for the external monitor, 1280 for the laptop panel). I don't think I've had this happen before. Run xrandr --fb 1280x800 black screen, and 'Sorry, Ubuntu 12.04 has experienced an internal error' dialog after reboot.
