In this article I will show you how to install the XFCE Desktop Environment on Debian Squeeze, Debian Wheezy and Debian Sid.

XFCE is in the local repo, so you do not need to update the /etc/apt/sources.list.
Install XFCE :
$ sudo apt-get install xorg xfce4 synaptic gdebi wicd
OR:
$ sudo aptitude install xorg xfce4 synaptic gdebi wicd
To install extra XFCE packages, do this:
$ sudo apt-get install xdg-utils xfce4-power-manager xfce4-goodies htop bzip2 zip unzip unrar-free
OR:
$ sudo aptitude install xdg-utils xfce4-power-manager xfce4-goodies htop bzip2 zip unzip unrar-free
