Every Linux distribution has its preferred default desktop UI setup, customizations and login screen. The graphical user interface (GUI) you see on most Linux operating systems is provided by a bundle of software applications called desktop environment (DE). This bundle will have wallpapers, icons, layouts, widgets and toolbars that work together to shape your overall Desktop user experience. However, most flavors of Linux distributions geared towards the use in Server/Data Centers only provides command line interface for administering it.
Ubuntu 24.04 will have GNOME as the default Desktop environment. While it is a clean DE with modern and clean user interface, some users will prefer to switch to their preferred Desktop Environment. One of the options in changing your Desktop Environment is KDE Plasma Desktop. KDE is known to be highly tweakable as it allows for extensive user customization options. A popular feature of KDE is the ability to create multiple virtual desktops and better organize your apps.
