Xubuntu是一个完整的基于 ">Ubuntu的GNU/Linux 发行版，但是更为轻量，比使用Gnome和KDE的Ubuntu系统更有效率，因为其利用了Xfce桌面环境。Xfce是一个供较老的或者配置较低的计算机使用的桌面系统。Xubuntu使用Ubuntu的高质量软件包，并且可以运行GTK2程序，以达到最大的效率。由于其与Ubuntu共享软件包的源，所以可在Xubuntu上面安装任何GNOME或者KDE的程序。
Xubuntu wallpaper has been updated for this release. The wallpaper is designed to integrate well with the new graybird theme.
The installation slide show has been updated for Natty Narwhal, and really displays the best of Xubuntu.
The Elementary Xubuntu icon theme has been updated.
Xubuntu is using the Droid font by default, since it is a lightweight, good visibility font.
The newly released Xfce 4.8 is included. The menus in Xfce 4.8 are now editable with any menu editor that meets the freedesktop.org standards. The suggested editor is alacarte.
