Ubuntu – Keyboard backlight not working on an Asus N56V

See this question.

The FN keys are not working

Using answer in this question I installed the asus-wmi-dkms_0.2_all.deb.gz package

Now, using xev I see that the keys emit keycodes (for backlight keys xev says for fn-f3 and fn-f4 keycode 237)

But no keyboard backlight, also volume keys have no effect

================ original question ========================================

I cannot enable the keyboard backlight
Seems that the leds class is missing
I've not found the classes used in Keyboard light hotkey (Fn + F3 and F4) rarely work on an Asus G60J
