Terminology

• X Windows : This layer is required by all graphical desktops. X Windows (usually served up by X.org) is responsible for drawing graphic elements onto the display. Without the X Windows server, neither a Window Manager or a Desktop Environment could create images on the screen. X Windows also creates the framework for moving windows, as well as interactions with the mouse and keyboard.
• Window Manager : While X Windows is responsible for drawing graphical elements, the Window Manager takes charge of controlling the placement and appearance of said windows. Unlike X Windows, the Window Manager can be customized with themes, menus, and more. Typical Window Managers include: Enlightenment, Gala, Mutter, KWin, Fluxbox, i3, JWM, Window Maker, and IceWM. The Window Manager requires X Windows, but does not require a desktop environment.
• Desktop Environment : The Desktop Environment requires both X Windows and a Window Manager, but adds a much deeper and seamless integration with applications (such that they are aware of one another), panels, system menus, status applets, drag and drop capability, and more. the goal of a good Desktop Environments is to focus on the overall user experience. The most popular Desktop Environments are GNOME, KDE Plasma, Pantheon, Mate, Cinnamon, Deepin Desktop Environments, and Budgie.
