Install Gnome Shell (and the classic Gnome desktop) in Ubuntu 11.10 Oneiric Ocelot

If we switch back to the classic desktop instead of Gnome or Gnome Shell want to use first thing we have to do is install Gnome Shell from the repositories of Ubuntu 11.10. To do this run:

$ sudo apt-get install gnome-shell

or Open the Ubuntu Software Center, from the launcher side of Unity and search for the string "Gnome Shell", select the corresponding entry and press the button "Install"

Certainly so in this way I discovered by accident that you also can download the Full Circle Magazine magazines from the Ubuntu software center (good point).

Once installed and Gnome Shell and we restart the session and from LightDM we can select the desktop you want to log in: Gnome (Shell), Gnome classic or Unity, according to which we have installed.
