Keyboard backlight not working

Hi
I have a new Asus ROG Zephyrus G GA532DU-AL005.
Some of the special keys (Fn +F5 to Fn+F12, Fn + ↑, Fn + ↓, the dedicated mute mic key, the dedicated key with a ROG logo on it) don't work (i.e. aren't seen in xev, while all the other key combinations are), which may be related?
I tried this :

$ ls /sys/class/leds
asus::lightbar@           input11::capslock@  input11::kana@     input11::scrolllock@  input13::compose@  input13::numlock@     input5::capslock@  input5::scrolllock@
asus-wireless::airplane@  input11::compose@   input11::numlock@  input13::capslock@    input13::kana@     input13::scrolllock@  input5::numlock@
$ls /sys/class/leds/asus::lightbar/
brightness  device@  max_brightness  power/  subsystem@  trigger  uevent
$cat /sys/class/leds/asus::lightbar/brightness
14

No matter what I write in it, /sys/class/leds/asus::lightbar/brightness always contain 14. And I'm not even sure lightbar is about keyboard backlight.
Any idea on how to make keyboard backlight work?
