Comment 0 for bug 749817

Binary package hint: xorg

I have a Thinkpad X201 connected through it's docking station/ultrabase to a Dell 2709W monitor. This was working fine under Maverick; normally with the internal monitor off but also with them mirrored or side-by-side.

I just upgraded this machine to natty. It booted up and showed grub on the external monitor ok, the loading screen, and then the gdm login screen. After I log in, I get a black screen on both the internal and external monitors, with just a white mouse pointer visible. The mouse pointer moves when I move the mouse. Nothing else appears; there's no disk light. I switched to vt1, which worked. Nothing was using substantial cpu. I kill-9ed gnome-session, which took me back to the gdm login screen. I tried the other session options including Ubuntu classic (no effects) with no more success.

When I undocked the laptop it worked ok, including running Unity.

(I hit bug 749809 while filing this so the apport data might be incomplete.)
