XFce is an easy-to-use and easy-to-configure environment for X11 released under the terms of the GNU/GPL license, based on GTK+, with pulldown menus and color icons, 3D widgets, etc.

XFce features now a set of applications including a powerful Window Manager xfwm, a toolbar/application launcher, a backdrop manager, a system sound manager for X11, a user friendly interface for mouse configuration, a pager providing a miniature view of all XFce desktops, a clock/calendar and at last but not least a filemanager, all sharing the same look'n feel.
