How to Change Login Screen to Cinnamon/Gnome3?

[skibum1981]

I originally installed LMDE 1204 RC1 with XFCE, and I then added Cinnamon, and I liked it so far, so I'm sticking with it. Unfortunately, though, I cannot figure out how to get the login screen to the cool one that Linux Mint 12 usually has. I.e., I want my login to look like:



But instead it looks like:



With the white LMDE background, of course, rather than that old Linux Mint 10 background (couldn't find a pic). Does anyone know how to change the login screen?

I believe LM12 uses LightDM for a login manager.
