  I am unable to use an external display on ATI Radeon IGP320M (U1) video
  card in a HP ze4365us laptop using Ubuntu 9.04.  The LVDS display works
  correctly, but I cannot get the VGA-0 display to work.  When I start the
  machine, the VGA port displays a clone of the LCD screen until X starts.
  I have tried to enable the display using xrandr --output VGA-0 --auto,
  but the display hooked up to VGA-0 remains off even though xrandr
  indicates it is active.
  
  Output of xrandr is below:
