kdm 4:3.5.9-0ubuntu3 (amd64 binary) in ubuntu hardy

 kdm manages a collection of X servers, which may be on the local host or
 remote machines. It provides services similar to those provided by init,
 getty, and login on character-based terminals: prompting for login name and
 password, authenticating the user, and running a session. kdm supports XDMCP
 (X Display Manager Control Protocol) and can also be used to run a chooser
 process which presents the user with a menu of possible hosts that offer
 XDMCP display management.
 .
 A collection of icons to associate with individual users is included with
 KDE, but as part of the kdepasswd package.
 .
 The menu package will help to provide KDM with a list of window managers
 that can be launched, if the window manager does not register with KDM
 already. Most users won't need this.
 .
 This package is part of KDE, and a component of the KDE base module.
 See the 'kde' and 'kdebase' packages for more information.
