I've been running Ubuntu with Gnome for some time now. I wanted to try out XFCE, so I tried the suggestion from the site http://www.psychocats.net/ubuntu/xubuntu and entered the following command:
$ sudo aptitude update && sudo aptitude install xubuntu-desktop
Unfortunately, this installed not only xfce but also changed the initial login screen. While I can tell the login manager to start a Gnome session, I would like to revert to my previous startup graphics and login manager.
How do I revert back to the normal ubuntu desktop?
