Dimming the screen

Hello,

I have a Pavilion g7 with

$ uname -a
Linux home02 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux

It's fully updated.

I've never been able to get the screen to dim.

I've tried the following,

but all it did was remove the slider control from the Brightness and Lock screen.

Thanks for all the help!

That is what I did to get around trying to manually getting the hotkeys to work to dim the screen.
I have a little red bulb in my taskbars/slits that I can toggle redshift on and off with.
It is pretty nice once you get it setup. I never heard about redshift till the other forum member
mentioned it and then I was lassoed into showing how to get it to work in our Window Managers and
I also have it running in Mate Desktop in Mint. I do not use Gnome 3 or Gnome Panels or Ubuntu 12.04 though so
you are on your own on that.
