Public bug reported: I believe this is not specific to the Latitude 2120. Running Oneiric Alpha 3 and when I plug a monitor in to the external VGA port, the display becomes garbled. Using the UI at this point is impossible. Also, the secondary display only shows the bar at the top and a black screen, no background is presented.
The only remedy is to remove the external monitor, at which point, Unity resets itself and becomes usable again.
