** Description changed:

  Binary package hint: xorg
  
  When I am using my laptop on its docking station, with laptop lid closed
  and using an external monitor, the display properties still sees the
  laptop monitor and allows me to turn it on/off and extend my desktop.
  
  Expected result:
  When the laptop lid is closed, the laptop screen should be considered disconnected.
  
  Discussion:
  Let me explain how this creates a problem. At home I use a docking station for my laptop. The lid is closed and the laptop is connected to the docking station. I use an external monitor, keyboard, and mouse. When I want to take the laptop away from home, I can undock it and open the lid and Ubuntu will switch to the internal screen. So far so good.
  
  When I close the lid and connect the laptop back to the docking station,
  Ubuntu thinks that the display is still on the laptop screen and will do
  one of two things:
  
  (1) Do nothing with the external monitor, leaving it off. If I then open
  the lid of the laptop while it's on the docking station, it will turn
  off the display on the laptop monitor and then show the display on the
  external monitor. Closing the lid turns off the external display and
  turns on the display on the closed laptop monitor.
  
  (2) extends the desktop display onto the external monitor which leaves
  me without panels, desktop icons, etc. since they are on the closed and
  inaccessible laptop monitor.
  
  Neither of these are helpful. If Ubuntu can consider the laptop monitor
  to be disconnected when the lid is closed, I believe that Ubuntu will
  see only one monitor and do the sensible thing.
