Bug description:
  Ubuntu 11.04 Natty
   2.6.38-10.46-generic 2.6.38.7

  Ubuntu hangs after grub when an external monitor connected to ASUS
  N73SV via HDMI or VGA.

  Xorg.0.log ends with:
  [     6.501] (==) intel(0): Silken mouse enabled
  [     6.501] (II) intel(0): Initializing HW Cursor
  [     6.507] (EE) intel(0): failed to set mode: Invalid argument
  [     6.507] 
  Fatal server error:
  [     6.507] AddScreen/ScreenInit failed for driver 0

  The syslog contains following lines:

  With the HDMI/VGA disconnected Ubuntu starts fine. After Ubuntu completely 
loaded the external display can be
  connected without problems. At this time it is detected properly and works 
perfect. The desktop is shared fine to it.
  i.e each time I turn it on I have to disconnect external display, wait until 
Ubuntu login screen displayed, then connect
  the external display again.
