       kdm - KDE Display Manager


       kdm [options] [tty]


       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
