Public bug reported:
On a cold boot, the UX32VD's keyboard backlight correctly functions, and
I can adjust it's brightness using Fn+F3 and Fn-F4.
After a suspend/resume the backlight is now off, the function keys do
not adjust it and trying to manually interact with its sys interface at
/sys/class/leds/asus::kbd_backlight/brightness has no effect
