Open the terminal and run sudo dpkg-reconfigure gdm. This will open up a new window allowing you to select either gdm or lightdm as the default login display manager.

Well for sure that solved the default manager problem with lightdm, But the greeter doesn't seems to be working right as the background at the login screen comes in pretty dull and boring solid color and the icons too are showing pretty scrambled – Arush Salil Apr 8 '13 at 21:21
