Installing the Gnome windows manager, our default GUI (Graphical User Interface), is really easy. Become your root user by entering the following command:
su
You should be asked for a password. After entering the password, your command line should end with the '#' sign instead of the '$', i.e.:
root@virilio:/home/ross#
Now issue the following command:
apt-get install gnome
Now reboot and you should have a GUI.
