Xubuntu is a complete GNU/Linux system, a variant of Ubuntu. As it uses the XFCE Desktop Environment it’s lighter and more efficient than Ubuntu (which uses GNOME) or Kubuntu (which uses KDE). It is ideal for older or low-end machines as well as thin clients and other systems requiring less bloat—and it looks & works great of course.
Xubuntu is shipped with top quality packages from the Ubuntu archives. It uses GTK applications as much as possible, ensuring maximum efficiency. If you wish, you can install any KDE or GNOME application on your Xubuntu desktop system, as it shares the Ubuntu package repositories. Other great GUIs are available also.
