During about last mont the bug did not show itself. Hence I changed the
status to Fix released. However, a related problem remains which I am
going to report separately.

** Changed in: linux (Ubuntu)
       Status: Triaged => Fix Released

Title:
  [HP ZBook 15] can not reduce brightness

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  machine: HP ZBook 15
  (Intel Core i7 4700MQ Haswell, NVIDIA Quadro K1100M 2GB, 1920 x 1080 display)

  I go to the settings/Brightness & Lock section.
  The button which should controll the screen brightness is on the right-hand side.
  I move it to the left-hand side but nothing happens. The screen brightness remains to be 100% (too much for me).
  The machine is running on the AC power cable.

  The machine uses an intel graphics driver.

  It contains also the NVidia card but that one is apparently inactive
  and the system did not offer me to install it.
