Public bug reported:

Filing this against xorg initially as I'm not sure if it's related to
the driver or if it's a Unity bug, though I've not seen this behaviour
on other systems.

Plugged an external monitor into the Thinkpad T510 (7375) using the
DisplayPort port.  The external monitor DID come alive and dislay at
least the 11.10 background, but Unity crashed (panel, launcher and
window-decorations all went away).  I had to drop to a console and reset
Unity to get all the controls back and working.

Tried this twice and same thing happened each time.  Plug in
DisplayPort, Unity, Window decorations, Launcher all disappear even
though external monitor comes on (also with no panel).  unity --reset at
console after unplugging external monitor to fix.

I'm also attaching a short video showing this as it occurs.
