[Bug 278727] Re: Lenovo X60: undocking with exterior monitor attached causes crash and reboot

[Bryce Harrington]

** Description changed:

  Using Hardy with kernel 2.6.27
  
  Steps to reproduce:
  
  Dock your laptop, plug an external monitor into the dock and set up X to
  use both screens.
  
  Now press the undock button. (You will need the intrepid kernel; 2.6.24
  freezes if you try to undock, see bug #189185.)
  
  When the light goes green, remove your laptop from the dock.
  
  Expected result: the system should return gracefully to a setup without
  an external monitor - e.g. bringing my panels back to the laptop screen.
  
  Actual result: the system appeared to hang. After returning it to the
  dock, it rebooted.
  
  UPDATE: I have tried to reproduce this but failed, so not sure what
  happened. However, it's definitely true that X does not figure out that
  my external monitor has gone away. Will possibly file an alternate bug.
