"echo 0 > /sys/module/video/parameters/brightness_switch_enabled" fully disables brightness control, I mean you can no longer change the brightness settings via the <Fn> keys. "echo 1 > /sys/module/video/parameters/brightness_switch_enabled" restore brightness control, yet with the aforementioned bug (cycling twice through the brightness indication bar).
