Bug Description
Binary package hint: xserver-
I use my laptop (1st gen Macbbok) with external monitor. The display is a HP w2207h, and the resolution is 1680x1050.
I can change the resolution without problem. Then the monitor is slip away few hours later. I try restart the X server, but on the monitor I doesn't see anything. So I get a black display on HP's screen, and on the Macbook's monitor I see the GDM.
I can't find anything in the logs, everything looks good.

Does the same problem happen with Ubuntu Gutsy Gibbon 7.10 for you? You can recheck it with the Live CD. Do you have Hardy with latest updates?
Please attach the following information and files:
Detailed list of steps to reproduce
How complete is the X failure?
+ Does ctrl+alt+f1 take you to a console?
+ Does ctrl+alt+backspace restart X?
+ Does mouse pointer still move?
+ Does the keyboard LED come on when hitting the CAPSLOCK key?
