  from system settings

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  system settings lock/brightness slider is absent.
  processed all the steps in https://wiki.ubuntu.com/Kernel/Debugging/Backlight and none of the workarounds work.

  results.log says that _BCL is broken though
