It is possible to configure NX server to get access to a X Desktop Manager (XDM) by setting the following keys in the /usr/NX/etc/server.cfg file:

#
# Specify a list of comma-separated 'hostname:port' values for XDM
# server.
#
#RoundRobinXdmList = "localhost:177"

#
# Enable or disable the XDM round robin query:
#
# 1: Enabled. Let NX Server decide XDM host according to hostnames
#    that are defined in the RoundRobinXdmList key.
#
# 0: Disabled.
#
#EnableRoundRobinXdmQuery = "1"

#
# Enable or disable the XDM indirect query:
#
# 1: Enabled. Let the user obtain a list of available XDM hosts.
#
# 0: Disabled.
#
#EnableIndirectXdmQuery = "0"

#
# Enable or disable the XDM direct query:
#
# 1: Enabled. Let client specify XDM host.
#
# 0: Disabled.
#
#EnableDirectXdmQuery = "0"

#
# Enable or disable the XDM broadcast query:
#
# 1: Enabled. Let client connect to the first responding XDM host.
#
# 0: Disabled.
#
#EnableBroadcastXdmQuery = "0"
 

If you want to run a XDM session, please select Desktop Unix-XDM in the NX Client  3.5.0 GUI -> General tab.

Depending on how the server is configured, you will be allowed to access the X Desktop Manager in one of the following ways that can be selected via the NX Client GUI -> XDM - Settings panel:
 

• - Let the NX Server decide : host and port mandated by the NX Server Administrator will be used.
   
• - Query and X Desktop Manager: you can specify and XDM enabled host.
   
• - Broadcast and XDM request: run a session on the first available server.
   
• - Get a list of available X desktop managers: run an indirect query to the specified host.
