I was trying to change my gdm user background, that is how this question came about. You can either use terminal with these commands:
# sudo -u gdm gnome-control-center
But the problem is that I could not find a way to get backgrounds to the gdm user backgrounds folder (custom background). The solution I found was an app called GDM3 Settings, it is a GUI to edit the gdm user background (from any directory) and theme. Here is a link to it http://www.webupd8.org/2011/07/gdm3s...wallpaper.html
I know this was off topic, but i figured it might help someone.
