Restore GNOME login?

[palz2015]

I am trying Xfce in my Ubuntu Karmic installation. I just logged out and I get the Xubuntu login screen. I prefer the GNOME one, and xubuntu-desktop sets Xfce as default. I tried editing /etc/x11/default-display-manager and it already says /usr/sbin/gdm.

Help please

Xfce doesn't have its own login manager, so you are still using gdm. You just switched to the Xubuntu gdm theme when you installed 'xubuntu-desktop'. This is why these metapackages are a bad idea, but everyone always tells people to install them.

How do I switch it back? And why does Xfce duplicate desktop environment names (in the 'session' menu it has Xfce session and GNOME listed twice)?
