Just updating this bug, since I'm running into it on my UX302LG. It looks like it should be fixed in future kernel releases, so it'd be useful to know if the patches mentioned here are actually in the next Ubuntu release (14.10):

My particular Asus notebook that is affected by this bug is a model M50Sv. There are various proposed fixes published on the net, but they all either do not work as described, or they are only temporary and do not carry over ofter re-booting. This bug essentially makes using Ubuntu and it's variants utterly impractical and unproductive. The eye strain caused by this bug is unbearable. This bug is accruing on other makes and models of notebooks which incorporate an ambient light sensor as well.
