Can you please follow /usr/share/doc/udev/README.keymap.txt to check
with the "keymap" tool if the key generates the correct key code? if
not, please give me the scan code, so that we can fix it in the keymaps.
Thanks!

Title:
Keyboard backlight does not work in Samsung Series 9 NP900X4C
Status in “udev” package in Ubuntu:
Incomplete
Bug description:
In Ubuntu 13.04, the keyboard backlight does not work in Samsung
Series 9 NP900X4C.
Adding the FN key mappings as described in
https://help.ubuntu.com/community/SamsungSeries9 does show information
in the notification area when pressing the keyboard backlight's + and
- buttons, but:
1) The notification always identifies the backlight as "full max"
2) It has no effect on the backlight - it's always off
When I first installed Ubuntu on this machine (12.10), even though the
fn keys never worked I did have intermitent backlight functionality -
the light sensor would sometimes work and I'd see light in the
keyboard.
I dual boot in Windows 8 and backlighting works there, so this is not
a hardware issue.
