Linux provides extensive support for several desktop environments like: GNOME, KDE 5, Unity, LXQt, . Moreover, desktop environments are majorly divided into two types: heavyweight and lightweight. Few desktop environments may look very interactive, but they might be ignored because they use more memory and processing power to run on Linux. For instance, GNOME and unity desktop environments fall in the heavyweight category whereas Xfce comes in the lightweight category, therefore it is better for older machines. In this article, the demonstration provides the installation of Xfce desktop environment on Debian 11:

Why XFCE desktop environment

This section enlists the importance of Xfce desktop environment over others: Xfce is lightweight desktop environment and is supported by lot of Linux distributions: For instance, there are few Linux distributions that comes with default Xfce desktop environment such as Zorin OSlite, MX Linux, Xubuntu, Manjaro Linux. Xfce desktop consumes very less memory (less than 200MB RAM) and it utilizes a minimum amount of CPU memory (300MHz). It is observed that every tool/package has some advantages and disadvantages as well, few dominant pros and cons of XFC:


  • Lightweight which makes it suitable for older machines
  • Modern and visually appearing
  • Interface like windows


  • Does not provide advanced level customization
