Now I'm confused. Your initial bug report was about simply
disconnecting the external monitor *while GNOME is running*, and
I understood it was the case without any suspend/resume cycle.
Did I misunderstand?

If I got it right, what would be good to have is:

  1. cold boot, plugged into the docking station with external monitor
  2. log into GNOME
  3. unplug the external monitor
  4. if it crashes, log in again, and send the Journal

and:

  1. cold boot, plugged into the docking station with external monitor
  2. log into GNOME
  3. disconnect from the docking station
  4. if it crashes, log in again, and send the Journal

Undocking laptops while they're suspended has historically been
fragile on a number of machines, so I'm not surprised that it causes
problems on yours.

Cheers,
