How do I enable X Display Manager Control Protocol (XDMCP) without a local display?
Resolution:
Release Found: Red Hat Enterprise Linux

Symptom:
The X Window System server that client machines login to, via the X Display Manager Control Protocol (XDMCP), does not need a local graphical login.

Note: It is assumed that you have the Gnome Display Manager (GDM) package installed and it has been configured to allow XDMCP network connections. Please see the relevant FAQs for more information.

Solution:
First, enable XDMCP support in the Gnome Display Manager (GDM).

Next, as root, use your favorite text editor to edit the file /etc/X11/gdm/gdm.conf. Scroll almost all the way to the bottom and you should see a section resembeling the following:


 
[servers]
# These are the standard servers.  You can add as many you want here
# and they will always be started.  Each line must start with a unique
# number and that will be the display number of that server.  Usually just
# the 0 server is used.
0=Standard
#1=Standard
# Note the VTAllocation and FirstVT keys on linux.  Don't add any vt<number>
# arguments if VTAllocation is on, and set FirstVT to be the first vt
# available that your gettys don't grab (gettys are usually dumb and grab
# even a vt that has already been taken).  Using 7 will work pretty much for
# all linux distributions.  VTAllocation is not currently implemented on
# anything but linux since I don't own any non-linux systems.  Feel free to
# send patches.  X servers will just not get any extra arguments then.


Comment out the 0=Standard line by placing the "#" character in front of it. The line would then look like this:


 
#0=Standard


Finally, save the file and restart GDM with the command: "killall gdm-binary" run as root from a virtual-console.


How well did this entry answer your question?
