# Chapter 1. What is Xubuntu?

## A short introduction

### Xubuntu is a community-developed, Ubuntu-based Linux operating system.

Xubuntu is an elegant and easy-to-use operating system. Xubuntu comes with Xfce, which is a stable, light and configurable desktop environment.

It is perfect for those who want to make the most of their desktops, laptops and netbooks, featuring a modern look and enough features for efficient, daily usage. It works well on older hardware too.

### About the name

The "X" in Xubuntu stands for Xfce, the desktop environment in Xubuntu. While the word "ubuntu" denotes the dependency on and usage of the Ubuntu core, it also represents the philosophical core of the operating system. A rough translation of the word ubuntu is "humanity towards others". To read more about the philosophy and ideals behind Ubuntu and Xubuntu, please refer to the Ubuntu Philosophy page.

In addition to using the Ubuntu core, Xubuntu also uses the infrastructure kindly provided and sponsored by Canonical Ltd., a company founded by Mark Shuttleworth.

### Version numbering

The Xubuntu version numbering scheme is based on the distribution release date. The first part of the release denotes the year while the second part denotes the month. For example, the first official Xubuntu version was released in June, 2006, thus its version number was 6.06. The latest Long Term Support (LTS) version is 16.04, codenamed Xenial Xerus.
