Took me about an hour to figure this out ... i know im slow
Just do fn "function" F8 and fn F7 to make it dimmer.
Also if you hold ctrl alt and tap F8 twice it will go to a all black screen ... then ctrl alt F7 to bring it back ... pretty nifty shoulder surfing feature =]
You can also log out to just a bash prompt by doing ctrl alt backspace.
I just wish the ctrl c and ctrl v worked for copy and paste as i used those the most .. shift + insert is just to damn far away and requires 2 hands =[
