Ubuntu – How to restore the standard Ubuntu Gnome login after trying Xubuntu

package-managementUbuntuxubuntu

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?

Best Answer

you don't have to reinstall ubuntu-desktop, for it is still there: all you have to do is to restore gdm at the startup (instead of the xfce login manager).

It's this info enough for you? I hope so: if not, I'll be here for you! :D

EDIT: since it could be useful to someone else, here we are. Fire up your terminal and write:

cd /etc/X11

sudo nano default-display-manager

then write inside that file

/usr/sbin/gdm

and close nano with CTRL+X

OR

if you prefer the graphical editor:

cd /etc/X11

sudo gedit default-display-manager

then write inside that file

/usr/sbin/gdm

and save it.
