Bug description:
  In Dell or ThinkPad (for these you need a kernel which includes fix
  for lp:1574498) notebooks with keyboard backlight, the keybindings to
  control the keyboard backlight don't emit any event to the userland,
  about the state change, nor they request userland to change it (as it
  happens in other models which emits KEY_KBDILLUM{UP,DOWN,TOGGLE}
  events), this causes unity/gnome-settings daemon not to restore the
  proper backlight after idle.

  Steps to reproduce:
   0) ensure your keyboard backlight is on, and
       gdbus call --system --dest org.freedesktop.UPower \
        --object-path /org/freedesktop/UPower/KbdBacklight \
        --method org.freedesktop.UPower.KbdBacklight.GetBrightness
      returns a value != from 0. If not, just call the SetBrightness
      method with a positive value, to turn on the backlight.

      Now turn off the keyboard backlight (or set it to another level)
      using the laptop keys, and run:
       gsettings set org.gnome.desktop.session idle-delay 1
      to make things easier to test.

   2) Wait one second and the screensaver should start. Wait the screen to
      be turned off. If you just changed the brightness level at the step above,
      once the screen is turned off, also the keyboard backlight should be turned off too.

   3) Now press a key or move the mouse.

  Expected behavior:

   4) The keyboard backlight should be set back to the previous level (so it should stay off
      or go back to the level you set before the idle timeout happened).

  Actual behavior:

   5) The backlight is set to the level it had at point 0).

  
  To reset the idle-delay, just call
    gsettings reset org.gnome.desktop.session idle-delay
