Xubuntu--unix

http://www.xubuntu.org/

Xubuntu is a complete GNU/Linux based operating system with an Ubuntu base. It is lighter on system requirements and tends to be more efficient than Ubuntu with GNOME or KDE, since it uses the Xfce Desktop environment, which makes it ideal for old or low-end machines, thin-client networks, or for those who would like to get more performance out of their hardware.

Xubuntu is shipped with top quality packages from the Ubuntu archives. Xubuntu will use, as far as possible, GTK2 applications, ensuring maximum efficiency. If you wish, you can install any KDE or GNOME application on your Xubuntu desktop system, as it shares the Ubuntu main and universe package selection.

The Xubuntu community makes use of the Ubuntu wiki, a collaborative environment where the community can edit all pages as needed. Important wiki pages are listed at the right.

The Xubuntu Manifesto

The team behind Xubuntu makes the following public commitment to its users:

• Xubuntu will always be free of charge, and there is no extra fee for the "enterprise edition", we make our very best work available to everyone on the same Free terms.
• Xubuntu includes the very best in translations and accessibility infrastructure that the Free Software community has to offer, to make Xubuntu usable by as many people as possible.
• Xubuntu is released regularly and predictably; a new release is made every six months. You can use the current stable release or the current development release. Each release is supported with security updates for at least 18 months.
• Xubuntu is entirely committed to the principles of free and open source software development; we encourage people to use free and open source software, improve it and pass it on.
  

Xfce是一个在Unix与Unix-like操作系统上运行的桌面环境，如Linux与FreeBSD，它主要是由鼠标设定，而它的设定档通常不会被普通用户看到。它的设计目的是"设计为可作为实际应用，快速加载及执行程序，并减少耗用系统资源"。(Olivier Fourdan, 原创者)

Xfce同时为程序设计者提供开发框架。除了Xfce本身，还有第三方的程序使用Xfce的程序库，如文字编辑器 - Mousepad，多媒体播放程序 - xfmedia 与终端机模拟器 - Terminal emulator。

Xfce建基在GTK+ 2.x之上。它使用Xfwm作用档案管理员。Xfce有点像另一个桌面环境，但却是商业的，CDE，不过在新版本中已经有较大分别了。

"Xfce"的名字最初是代表"XForms Common Environment"，但自从那时起，Xfce已被重写了两次而且不再使用XForms 工具包。名字虽然仍被保留为Xfce，但现在已不会将其大阶为"XFce"。而开发者现在的任务是要使Xfce不再代表任何东西。

现在最新版本为4.2.2，是在2005年5月17日发行的。

Xfce并不像KDE与Gnome般，它并不常见于Linux发行版中。不过仍有少部份发行版用它作为缺省的桌面环境，但大型发行版如Debian 与Fedora Core则只将其作为可选择配件。

部份使用Xfce作为缺省桌面的发行版:

• Xubuntu
• Xfld (Xfce live demo)
• Archie
• Morphix (LightGUI version)
• Slax (Popcorn Edition)
• Whoppix
• Zenwalk
