For me this also leaves just the keyboard backlight, which doesn't work.
I believe that's a UEFI bug though, since Samsung's special hardware features are disabled in UEFI mode.
If the backlight is working for you, this probably means you're not using UEFI - although if you have your backlight working under UEFI, I'd be interested to hear.
