I gave up on wanting brightness levels to be triggered by an event as I realised that the "working" monitor would simply be the one I'm staring at, i.e. the computer has no idea what my eyeballs are doing.
It'd be neat if you could use a webcam to do that
hahaha~! That was my first thought as well! Eye tracking... don't know how to do it, but it would be very cool!
