Public bug reported:
When I undock my system the screen on the notebook keeps black, so I
have to either shut the system before undocking or force it off after
undocking while running. Docking the running system does not use the
external monitor afterwards.
Tried to Do Fn-SwitchMonitor keys and switching to console, but that
didn't work when undocking. When docking, it happened that something
appeared on the screen (note: dual-screen) but wrong and only if the lid
is not closed!
