** Description changed:

  This is on a freshly installed and dist-upgraded Natty installation.
  
  Steps to reproduce:
  - Plug in an external screen and wait a couple of seconds for it to get recognized.
  
  Expected result:
  - Both screens draw correctly and can be used
  
  Actual result:
  - The background goes "black" on both screens (whereas it should have the default Ubuntu colored background). Unity and the top panel are visible on the built-in display; Only the top panel is visible in the external display.
  
  If I open a terminal on the main display, it appears fine, but response
  is very sluggish; the system takes up to 2 seconds to "catch up" with
  actions, keystrokes and dragging actions (the cursor pointer itself is
  fine and tracks movement without any lag).
  
  If I drag a window around, other than it being very slow (takes up to 2
  seconds to finally catch up with the dragging pointer), it leaves
  "traces" of itself around, as if the intermediate steps were not being
  erased before redrawing the window in a new position. This happens in
  either display.
  
  When I unplug the external display, everything goes back to normal.
  
  I'm attaching pictures of the internal and external screen upon
  connecting the external display, of both screens after I've dragged a
  window around a bit and left a lot of residual window pieces, and how
  the internal display looks after unplugging the external display (i.e.
  normal).
  
- Happens on these four systems:
+ Happens on these five systems:
  - Three Dell Latitude 2110, slightly different specs
  - One Dell Inspiron Mini 1018
+ - One Asus Eee PC 1001PX
  
  The common component seems to be this one:
