** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  My laptop hangs when I just connect an external monitor to it. This is even 
before I configure any type of mirror screen or extended desktop. The instant 
VGA connector touches the port, the system is lost. The only way out is by hard 
reboot. I have tried 'Ctl-Alt-Backspace' (after enabling it), ssh-ing into the 
laptop but nothing works.  This did not happen in jaunty. 
  I use my laptop to display presentations regularly so this is a very big loss 
of usage at work.
  
  This is a very bad regression. People can inadvertently loose all unsaved 
data just in the course of trying to display externally.  
  Enabling/Disabling Compiz does not seem to make any difference.
  
  I looked at Bug:438000 which seems to be compiz related and happens
  AFTER somebody tries to configure the screen for external monitor.
  
  Please let me know what other debug information may be needed for this.
