It works but not fully. Something is changing /sys/class/leds/asus::kbd_backlight/brightness after script.
See my test with a modified asus-keyboard-backlight.sh root@felipe-G51JX:~# echo 0 > /sys/class/leds/asus\:\:kbd_backlight/brightness root@felipe-G51JX:~# /etc/acpi/asus-keyboard-backlight.sh up ORIGINAL VALUE: 0 up NEW VALUE: 1 File value after echo ...0 File value after 1 second ...129 File value after 2 seconds ...129 root@felipe-G51JX:~# /etc/acpi/asus-keyboard-backlight.sh up ORIGINAL VALUE: 129 up NEW VALUE: 3 File value after echo ...129 File value after 1 second ...131 File value after 2 seconds ...131 root@felipe-G51JX:~# /etc/acpi/asus-keyboard-backlight.sh down ORIGINAL VALUE: 131 down NEW VALUE: 3 File value after echo ...131 File value after 1 second ...131 File value after 2 seconds ...131 root@felipe-G51JX:~# Nothing appear in syslog about it... So it is really weird ...
