KDE Display Manager for X11

 KDM manages a collection of X servers running on local or remote machines.
 It allows users to easily log into their preferred desktop environment, connect
 to a remote XDMCP server, or shut down the system.
 KDM supports custom themes and can display a list of users with icons.
 Additional user icons can be found in the 'kdepasswd' package.
 This package is part of the KDE base workspace module.
