Mate is Gnome 2 fork (Gnome 2 is now not maintained) which enables you to use old Gnome 2 desktop user interface. It is same as Gnome 2 but with renamed packages and applications which lets you install Gnome 2 and Gnome 3 simultaneously on same Ubuntu installation. The Gnome 2 and Gnome 3 desktop environments can not be installed at the same time, but Mate can be installed with Gnome 3 because of its renamed packages and applications.
