[Linux] Replace Unity with another desktop environment

If you too feel like Unity is a nightmare and would like to switch to another desktop environment, but do not fancy to reinstall everything from scratch, know that it's indeed possible to switch between multiple installed ones at login time, although it's not recommended to have more than one installed.

This example will show how to convert Ubuntu(Unity) in XUbuntu(Xfce), but can be adapted to any desktop environment you like (simply install the desired environment instead of xubuntu-desktop).

First, install XUbuntu desktop:

sudo apt-get install xubuntu-desktop

Now if you log out, before you log in, you'll be able to select which desktop environment you want to log in to by clicking on the Ubuntu logo and selecting another session (ie: XUbuntu Session).

If you wish to remove the old environment to clean things up a little, run:

sudo apt-get remove activity-log-manager-common compiz compiz* gnome-applet* gnome-bluetooth gnome-control-center gnome-desktop* gnome-pane* gnome-power-manager gnome-screensaver gnome-screenshot gnome-sessio* gnome-shell-common gnome-termina* gnome-user* hud libzeitgeist* nautilus overlay-scrollba* python-zeitgeist unity unity* zeitgeist zeitgeist*

Afterwards, you may also want to run:

sudo apt-get autoremove

and if you have installed deborphan:

sudo orphaner --purge
