  G750JH,  Asus-WMI, LCD Backlight dimming not working

Status in The Linux Mint Distribution:

Bug description:
  On the Asus G750JH like many other Asus laptops have function keys to
  control both the keyboard backlight led's ( Fn + F3, Fn + F4 working)
  and the dimming of the lcd backlight. On mine they are Fn + F5 and Fn
  + F6 which have no effect.
