XDMCP Configuration - KDM

This page will tell you how to configure KDM for XDMCP. If you are not using KDM, this page is not intended for your use. To determine what DM you are using, follow the instructions on the XDMCP page.

Configuring KDM

KDM uses a configuration file called kdmrc. You'll need to figure out where that file is on your system. It may be in /etc/kde/kdm/kdmrc, but you may have to search for it using the locate command, or the find command.

Small section of your kdmrc file

# -- many lines omitted --
      [Xdmcp]
      Enable=true
# -- many lines omitted --

The above is NOT the complete kdmrc file. You must open this file, locate these two lines, and make sure you change false to true. Once your kdmrc file is configured properly, continue with the remainder of the instructions on the XDMCP page.

For disabling the graphical login on the server (keeping it in text-mode only on the server screen), you have to edit the file Xservers which probably lives in the same directory as the aforementioned kdmrc. It usually contains one line per local graphical login (yes, you could even have multiple graphical consoles). Just comment them all out.

On a Debian system the filename might be /etc/kde3/kdm/Xservers, and you have to comment out the line

       :0 local@tty1 /usr/X11R6/bin/X -nolisten tcp vt7
