To all who upgraded to Natty and experiencing a blank screen with an
external display: Go to one of the Console sessions (e.g. ctrl+alt+f1),
then rename the ~/.config/monitors.xml file. This resets the Gnome's
Monitor settings and should give you a working Unity / Gnome Deskop on
both displays. You can then try to configure you Monitor settings again.

However, the thing I'm experiencing here is, that when I try to disable
the notebook display to work on the external display (via VGA) only, the
notebook display goes off and the external display goes blank. And
that's it. I have to restart X to get back to GDM.

Running on an Acer Aspire TimelineX 4820TG, using Intel graphics only
(ATI disabled via switcheroo).

Regards

Alex
