Xubuntu is an elegant and easy to use operating system. Xubuntu comes with Xfce, which is a stable, light and configurable desktop environment. Xubuntu is perfect for those who want the most out of their desktops, laptops and netbooks with a modern look and enough features for efficient, daily usage. It works well on older hardware too.
Xubuntu (zoo-buntu) is, as described, an excellent choice for modest hardware, providing a lightweight and full-featured experience via the Xfce desktop environment. Based on Ubuntu, it follows the same long-term and bi-annual release schedules as does all the Ubuntu “flavors” (distributions focused around various desktop environments). It is known for its stability and easy of use and is well supported with an active community.
