⁠B.2. Desktop Environments and Window Managers

Once an X server is running, X client applications can connect to it and create a GUI for the user. A range of GUIs are available with Fedora, from the rudimentary Tab Window Manager (twm) to the highly developed and interactive desktop environment (such as GNOME or KDE) that most Fedora users are familiar with.

To create the latter, more comprehensive GUI, two main classes of X client application must connect to the X server: a window manager and a desktop environment.

⁠B.2.1. Desktop Environments

A desktop environment integrates various X clients to create a common graphical user environment and a development platform.

Desktop environments have advanced features allowing X clients and other running processes to communicate with one another, while also allowing all applications written to work in that environment to perform advanced tasks, such as drag-and-drop operations.

Fedora provides two desktop environments:

GNOME — The default desktop environment for Fedora based on the GTK+ 2 graphical toolkit.
KDE — An alternative desktop environment based on the Qt 4 graphical toolkit.

Both GNOME and KDE have advanced-productivity applications, such as word processors, spreadsheets, and Web browsers; both also provide tools to customize the look and feel of the GUI. Additionally, if both the GTK+ 2 and the Qt libraries are present, KDE applications can run in GNOME and vice versa.
