Title:
  [Asus UX32VD] Backlight controls have no effect after suspend in most
  recent kernel

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  After recent updates, the backlight doesn't work after suspend on my
  Asus UX32VD laptop. The hotkeys work as far as the Unity graphical
  indicator goes, but there is no change in backlight. The hotkeys used
  to work, and have worked for the last couple of years.

  Backlight is restored and does work after restarting, but can no
  longer be modified after suspend.

  This is the output from 
  ls /sys/class/backlight > backlight
  "acpi_video0
  acpi_video1
  intel_backlight"

  This is the output from 
  grep -r . /proc/acpi > acpi
