Same problem on an Asus UX331U. In Ubuntu 18.04 setting kbd backlight worked, it's broken in Ubuntu 18.10.
Oct 1 17:43:19 avis gsd-power[2143]: gsd_power_ backlight_ abs_to_ percentage: assertion 'max > min' failed
i am able to manually control the backlight on the shell using leds/asus\ :\:kbd_ backlight/ brightness <<< 3
sudo tee /sys/class/
(replace 3 with [0..3] for brightness levels)
