screen brightness control is backwards

[Scott Palmer]

Increase brightness key on my keyboard (func-f3) makes the screen more dim.
Decrease brightness key on my keyboard (func-f2) makes the screen more bright.
The gnome-shell on-screen display of brightness is backwards also.

I see on google search results that this was a problem with older kernels. I guess the problem is back / possible regression.
