<pre>Booting with "video.use_native_backlight=1" boot paramenter, causes a weird
behaviour:
Using the fn keys it now actually changes the display brigthness, however after
that display brightness starts "bouncing" from 100% to value set by fn keys...
It will stop bouncing after issuing su -c "echo 0 >
/sys/class/backlight/intel_backlight/brightness"</pre>
