Linux uses the X Window system as the underlying software for graphical display. Two popular desktops built on top of X Windows are the K Desktop Environment (KDE) and Gnome. They are intuitive to use and customizable. Currently the default desktop in the labs is KDE.
KDE comes with a integrated file browser (Dolphin) and an integrated web browser (Konqueror), a simple text editor (kwrite), several multimedia applications and many other applications.
