![]() ![]() For example, a KDE user may install and run GNOME applications such as the Epiphany web browser, should he/she prefer it over KDE's Konqueror web browser. Note that users are free to mix-and-match applications from multiple desktop environments. Additionally, most desktop environments include a set of integrated applications and utilities. Desktop environments simply provide a complete and convenient means of accomplishing this task.Ī desktop environment bundles together a variety of X clients to provide common graphical user interface elements such as icons, windows, toolbars, wallpapers, and desktop widgets. The user is free to configure their GUI environment in any number of ways. X is built as an additional (application) abstraction layer on top of the operating system kernel. As such, the visual styling of X-based environments varies greatly different programs may present radically different interfaces. X does not mandate the user interface - individual client programs known as window managers handle this. X provides the basic framework, or primitives, for building such GUI environments: drawing and moving windows on the screen and interacting with a mouse and keyboard. ![]() Prior to installing a desktop environment, a functional X server installation is required.
