Bug Description
I have a Google (Asus) Nexus 7. If I use "System Settings...." -> "Brightness & Lock" to change the screen brightness the brightness changes as I move the cursor but goes back to minimum brightness as soon as I stop moving the cursor.
If I try to set the brightness by hand I see the same thing.

It is /usr/bin/luxd that is broken. It reads /sys/bus/

Dividing show_lux by 100 to get brightness seems incorrect as show_lux seems to go up to about 127 and brightness goes from 0 to 255.
I fixed the problem by killing luxd. In any case I don't a need a shell script looping once a second as my Nexux 7 is already too slow.
