Title:
  Laptop Monitor Brightness reduced to minimum and disabled after
  disconnection from external monitor.

Status in The Linux Kernel:
  Invalid

Bug description:
  Hi,

  I have the following problem under Ubuntu 14.04. As soon as I
  disconnect my external monitor from my Laptop (Lenovo X1 Carbon), the
  brigthness is reduced to minimum (backlight switches off) and I can
  not increase it again. When I use the brightness control keys the
  brightness bar shows that it is set to maximum even though it clearly
  is not. Using the control keys still changes the brightness bar but
  does nothing to the brightness itself.

  Upon a restart of the laptop the brightness returns to its maximum and
  is controllable again.

  I encountered this problem under the Unity version shipped with Ubuntu
  14.04, but it might happen with other desktop managers as well.

  This problem did not exist when my Laptop was running under Ubuntu
  13.10.
