How to enable XDMCP in GNOME Display Manager (gdm) for Solaris 10,11

by admin

This post describes how to enable XDMCP, which is disabled by default, in the GNOME Display Manager (gdm). XDMCP, or X Display Manager Control Protocol, allows login to gdm from remote X servers.

For Solaris 10

1. Change the default “Enable=false” to “Enable=true” in the [xdmcp] section of /etc/X11/gdm/gdm.conf:

# vi /etc/X11/gdm/gdm.conf
[xdmcp]
Enable=true

2. Restart the gdm2-login service for the changes to be effective.

# svcadm restart svc:/application/gdm2-login:default

For Solaris 11

1. Add a line “Enable=true” in the [xdmcp] section of /etc/gdm/custom.conf:

# vi /etc/gdm/custom.conf
[xdmcp]
Enable=true

2. Restart the gdm:default service for the changes to take effect.

# svcadm restart svc:/application/graphical-login/gdm:default

How to open a XDMCP Connection from Solaris 11 Login Manager

On Gnome, we can use two programs to start XDMCP sessions. The first one, tsclient is just a front-end from the second command. This second command, Xephyr that replaces Xnest, can be launched like this example.

# Xephyr :1 -screen 1200x800 -query [host IP address]
