Title:
  Backlight does not work on sony vaio sve1112

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  Using the default ati open source driver hotkeys are not working, echo
  commands are not working but files exist in sys/class/backlight.

  I used acpi_backlight=vendor , legacy and also the
  video.use_bios_initial_backlight=0 with no effect.

  Reverse mainline kernel version bisecting revealed the fix landed in
  the transition from 3.6.11 raring to 3.7-rc1 quantal.
