Keyboard backlight
Asus
The keyboard backlight file is usually locked out from editing. To unlock this file at bootup, you will need to create a systemd service.
/usr/lib/systemd/system/asus-kbd-backlight.service
[Unit] Description=Asus Keyboard Backlight Wants=systemd-backlight@leds:asus::kbd_backlight.service After=systemd-backlight@leds:asus::kbd_backlight.service [Service] Type=oneshot RemainAfterExit=yes ExecStart=/bin/chmod 666 /sys/class/leds/asus::kbd_backlight/brightness [Install] WantedBy=multi-user.target
You are now able to use a keyboard backlight changer script. For an example, see ASUS G55VW#keyboard backlight script.
