KDE-Forum.org

Hello, I'm installing debian 4.0 and KDE3.5 on a server and I would like to configure kdm to serve remote logins (with xdmcp) but not run on the local display. How can I configure it? On the previous versions, it was possible through removing a line from /etc/X11/Xservers file but now it seems that this file is missing. Thanks, Edouard
