NAME

       kdm - KDE Display Manager

SYNOPSIS

       kdm [options] [tty]

DESCRIPTION

       kdm  is  the  KDE  display manager also known as login manager. It shows a graphical login
       screen for username and password. After authenticating the user it starts a session.
       kdm can be configured for remote login via XDMCP. XDMCP is the "X Display Manager  Control
       Protocol" which is used to set up connections between remote systems over the network.

       kdm  is  a derivative of xdm. man 1 xdm may provide useful information (requires installed
       xdm). For X-related problems try man 7x X and man 1 startx.
