Bug Description
This is part of the master bug 824099
When connecting an external monitor, external screen is entirely black, except for the top panel, and the built-in display shows a "dead zone" on the top fourth of the screen, while the bottom 3/4ths are alive and well. I'm attaching a screenshot of the internal display of an affected Intel machine.

I remember fixing this issue at least a month ago...
I did a fresh install on my core i3 330M today and updated the system. I plugged in an external monitor (max res 1280x1024). I cannot reproduce the issue as reported here.
I am using a Ubuntu downloaded from the daily repository on the 14 of august...
