What you really want is to get DEC to support XDMCP so you have some
control of the
login prompts.  Since that is not likely in the near term, try this.

Chad showed how to start the Xserver on the DS3100 without a login prompt.

On the VMS machine, possibly in systartup_v5.com:
	$ set display/permanent/transport=decnet/node=DS3100_NODE_NAME
	$ run sys$system:decw$startlogin

This will start the login process, which will start the session, which
will start the login process
so you can log in and out of the DS3100 Xterminal.  There appear to be
many problems that
can break this loop, so you may need to restart the login process
again.

Since the display pseudo device still exists you  need to do
	$ show dev ws
to find the display devices and then
	$ show display wsXX
to find the display that points to you DS3100.
	$ define decw$display wsXX
sets up your default display again and
	$ run sys$system:decw$startlogin
restarts the login prompt sequence.

There might be a better way, but this has worked for us.
