[Chris Coulson <chris.coulson@xxxxxxxxxxxxx>]

Public bug reported:

Every time I undock my laptop or use the display settings panel to turn
off my external screen, I end up with a blank laptop panel with just the
mouse cursor visible. Sometimes I also cannot switch to a VT although I
can connect to the machine via SSH and do "sudo restart lightdm" to tear
down X and restart my session. Most of the time this happens though, I
just end up killing the power and restarting, as this is easier than
firing up another machine :)

I can undock successfully if I log out of my session first (so just the
lightdm greeter is displayed), which is an annoying inconvenience.

Attaching gdb to compiz shows that it hangs, but restarting compiz is
not enough to recover it. I need to restart X too
