Ubuntu is one of the most popular Linux distributions, known for its user-friendliness, stability, and flexibility. While many users associate Linux with the command line, Ubuntu has long supported a wide range of Graphical User Interfaces (GUIs) that make the system more accessible to newcomers and professionals alike. In this article, we’ll explore the most commonly used GUIs in Ubuntu, their differences, and how to choose the right one for your needs.

What is a GUI?

A Graphical User Interface (GUI) is a visual way of interacting with a computer, as opposed to the traditional command-line interface (CLI). GUIs include windows, icons, buttons, and menus that allow users to interact with the system using a mouse and keyboard, making it easier to navigate and perform tasks without memorizing commands.

Default GUI in Ubuntu: GNOME

Since version 17.10, GNOME has been the default desktop environment in Ubuntu. GNOME is modern, clean, and highly customizable, offering:

  • A minimalist, distraction-free interface

  • Integration with GNOME apps like Files, Terminal, and Settings

  • Support for extensions to tailor your experience

  • Frequent updates and a large user community

GNOME provides a solid balance between usability and performance, making it suitable for both beginners and developers.
