Without the Linux desktop environment or GUI, any Linux operating systems including Ubuntu 20.04, 18.04 LTS, or older versions are difficult to operate, especially for beginners. And above that choosing right and the best GUI for the Linux system will not only enhance the experience but also makes it quite friendly to operate with various functions and applications of Linux. By default, Ubuntu Server does not include a Graphical User Interface (GUI). A GUI takes up system resources (memory and processor) that are used for server-oriented tasks. However, certain tasks and applications are more manageable and work better in a GUI. Therefore XFCE Desktop Environment (GUI) On Ubuntu 20.04 comes into play.
