Public bug reported:
I have been having regular system freezes after switching from using my
laptop stand-alone to waking it up on a docking station with an external
monitor. I have seen this using two identical docking station plus
monitor combinations. I am still trying to find a pattern. I was able
to ssh in and use apport to save this bug information. The gnome-shell
process was hung at 100% CPU utilisation.
