Xfce is a lightweight desktop environment for UNIX-like operating systems. It aims to be fast and low on system resources, while still being visually appealing and user friendly. Xfce embodies the traditional UNIX philosophy of modularity and re-usability. It consists of a number of components that provide the full functionality one can expect of a modern desktop environment. They are packaged separately and you can pick among the available packages to create the optimal personal working environment.
Xfce provides a complete desktop environment while remaining lightweight and thus running well on more modest or older hardware although it runs equally well on modern systems. It is the default choice of many distributions, not just for its light footprint, but also due to being modular and very customizable. It also has a slower pace of development and tends to be very stable. Some find the more frequent changes made by other desktop environments disruptive and prefer the more steady and deliberate pace of Xfce’s development process. As an example of this, the most recent release on Xfce spanned a period of four years. Great care is taken to prioritize stability and performance. Xfce is fast, stable and flexible and has proven to be one of the more popular options for many Linux users.
