I was searching how to enable ASUS ROG G752 keyboard leds and I didn't find any info on that subject besides that - it is not possible to enable these. However I discovered kernel has there something to provide this and that it is so easy to enable these as root. There is 3 brightness levels so,

disable leds : echo 0 >> /sys/class/leds/asus\:\:kbd_backlight/brightness

max brightness: echo 3 >> /sys/class/leds/asus\:\:kbd_backlight/brightness

So how would I make this available for users?

I had to add "ACPI_OSI=" to kernel commandline in my asus laptop in order to get backligth keys working. You can try it hitting 'e' on grub menu, modifing commandline and booting with F10. If it works make it permanent adding that option to "/etc/default/grub" and regenerating grub configuration.

Option "ACPI_OSI=" did not get backlight keys working on f25 with that. Instead I wrote small python lib to control my ROG keyboard backlight via the D-Bus interface. Asus ROG Linux extras
