** Description changed:

  Hi,
  just upgraded and rebooted (been quite a while since I rebooted so lots of 
things probably changed in the mix).
  
  The system initially logged in and my screen layout was lost (instead
  ie, the monitor on the left was on the right).  I changed that back,
  logged out and back in.
  
  Now, occasionally and seemingly randomly the larger display goes black for 
1-2 seconds during usage.
  It often occurs when switching desktops via hotkeys, but sometimes at other 
random points.
  
+ After playing a bit, I'm pretty sure the reason is that I'm getting the
+ vesa driver instead of the intel one.
