XFce is another desktop environment, suitable for computers with not much memory or processing power. It's based upon the same GTK libraries that are in use by GNOME, so it shares some of the look and feel of the GNOME desktop. That said, it comes bundled with a number of Xfce-specific applications to replace GNOME tools such as nautilus.
Some people just prefer the simplicity of Xfce, so we will leave it up to you if you want to use it. You can access it in the same way as KDE (described previously) and a sample desktop is shown in Figure 3.12.
