Asus GL553VE laptop keyboard backlight uncontrollable and Fn keys not
working
Status in linux package in Ubuntu:
Confirmed
Bug description:
There are problems with Asus GL553VE laptop Fn buttons and keyboard backlight
1) Keyboard backlight uncontrollable
2) Most FN keys don't work
There is no way to control keyboard backlight at all (already tried
all possible ways found in internet)
Missing /sys/class/leds/asus::kbd_backlight (asus-nb-wmi modprobed)
try all possible variants with acpi_osi and acpi_backlight from forum
- no effect.
Install kernel 4.9 and even 4.10 latest RC - no effect (only got
control over airplane led).
Keyboard backlight is always on or always off (last state from windows)
Fn keys not working:
F1(Zz Suspend) F2(Airplane) F3(Kb brightness down) F4(Kb brightness up)
F5(Brightness down) F6(Brightness up) F7(Screen dim) F9(Touchpad disable)
Workjng: Sound Mute + - (F10 F11 F12)
