Xubuntu, pronounced as Zooboontoo, 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.

Minimum system requirements:

• To run the Desktop CD (LiveCD + Install CD), you need 128 MB RAM, when using the Alternate Install CD you can do with 64 MB.
• To install Xubuntu, you need 1.5 GB of free space on your hard disk.
• Once installed, Xubuntu can run with 64 MB RAM, but it is strongly recommended to use at least 128 MB RAM.

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.

Ubuntu does not yet have Xubuntu discs available through ShipIt, so we can't support it by pre-purchasing discs from Ubuntu. Therefore Xubuntu discs are produced using the normal On-Disk.com "Burn-on-demand" model.
