I'm going to venture a guess that the NoMachine server software is
actually *launched* as a process in your desktop session, so if you
haven't already logged in, the server software hasn't been launched
yet.

For most programs, the usual solution for something like that is to
have the daemon software launched as part of the init scripts, i.e.
from under /etc/init.d/. I don't have any personal experience with
NoMachine, though, so I don't know if it would require an X server's
credentials to launch.

As for the headless scenario, the simplest solution would be to run an
X server which doesn't expect any real hardware, like xvfb.
