Title:
  Brightness hotkey broken on UX302LG

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Brightness control key is broken on UX302LG laptop.

  Other hotkeys work (as per Bug #1270661) .

  Soft control works and is able to dim screen brightness.

  - Key does not output anything using xev.
  - Nothing shows up using acpi_listen when pressing the key.

  Tried acpi_type=vendor with no luck.

  From discussions I had, next step would probably be to dump DSDT from
  /proc and try to recompile them with the Intel ASL compiler that could
  indicate where problem lies, fix the error and use that specific blob
  at boot time.
