Title:
  [HP Compaq nx6310] Function buttons for brightness stopped working

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  In 14.04 using kernel 3.13 the special function buttons of this HP
  Compaq nx6310 laptop used to work correctly. I could increase or
  decrease brightness, invoke the battery settings (mostly useless but
  it worked), switch to an external display or enter sleep mode. The key
  functions are invoked using Fn + the key with the designated function
  as listed below.

  Fn + F3 - Sleep - button/sleep SBTN 00000080 00000000 K
  Fn + F4 - Switch to external display - video/switchmode VMOD 00000080 00000000
  Fn + F8 - Battery information - button/battery BAT 00000080 00000000 K
  Fn + F9 - Brightness down - video/brightnessdown BRTDN 00000087 00000000
  Fn + F10 - Brightness up - video/brightnessup BRTUP 00000086 00000000

  I went through the troubleshooting steps described at
  https://wiki.ubuntu.com/Hotkeys/Troubleshooting. In 14.10 none of
  these buttons work. Using acpi_listen I found that no events are fired
  in 14.10, but under 14.04 these buttons do indeed fire ACPI events and
  thus work correctly. The ACPI events listed above are fired in 14.04
  using kernel 3.13 but are not fired under 14.10 using kernel 3.16.

  Using xbacklight I can still change the brightness in 14.10, if that
  information is of any help.
