Installing Other Desktop environments in Ubuntu

If you want to change Unity and install anything else (like KDE) in Ubuntu 12.10, then this article is for you. Just copy-paste the commands into your terminal, press enter … wait a little bit for the packages to download and you are ready. Logout, pick your favourite Desktop Environment and log back in.
It’s insanely simple:
Install KDE
$ sudo apt-get install kde-standard
sudo apt-get install kde-full

Install GNOME 3
$ sudo add-apt-repository ppa:gnome3-team/gnome3
sudo apt-get update
sudo apt-get install gnome-shell

Install XFCE 4
