Customizing the look and feel of a Linux desktop can be achieved through graphical user interfaces (GUIs) and other window managers. Desktop environments like KDE Plasma, GNOME, Xfce, and LXDE are available. These GUIs allow for users to alter their background image, color schemes, themes, widgets, icons, fonts and other visual elements. Additionally, users can personalize their workspace by configuring features like window placement and taskbar position. A user can create an aesthetically pleasing desktop with all desired features enabled with proper configuration settings within the GUI environment or via a command-line interface (CLI).
