[lug] Ubuntu 14.04 Unity Desktop Config Files?

[stimits at comcast.net]

Hi,
 
I have a small system with Ubuntu 14.04 and Unity desktop. I'm trying to configure the desktop through file edits rather than the GUI tool. Specifically, I'm looking for the files which are listed in the GUI as "Brightness & Lock". Is anyone here familiar with the location of this config file?
 
Thanks!
