Title:
  TOSHIBA L870-18J: Brightness keys do not work

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  The problem is that brightness is at full and I cannot change it. The Fn+F2, Fn+F3 keys do not do anything.
  I have tried adding boot parameters like nomodeset, acpi_hardware=vendor etc. But nothing has worked for me.
  I even tried the /sys/class/backlight way but there is a problem. This directory is empty.
  I am using ubuntu 12.04.2 64bit and I have tried both open source and amd proprietary (13.1) drivers (even the  13.2 beta).
  I even tried the latest mainline kernels up to 3.8.1 which also did not solve my problem.
