Title:
  Dell Latitude 2110: Brightness keys come through two input devices

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  According to <https://wiki.ubuntu.com/Hotkeys/Troubleshooting>, "If
  the events are reported by more than one input device then report a
  kernel bug (Ubuntu linux package) because it should only send the
  event on one device."  On my Latitude 2110, the brightness control
  keys (Fn+Up and Fn+Down) seem to appear through two different devices,
  /dev/input/event3 ("AT Translated Set 2 keyboard") and
  /dev/input/event4 ("Video Bus").  The keys also control the screen
  brightness, even in a text console.
