Title:
  Screen keeps dark when docking or undocking

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  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!
