You don't have to arrange for spacenavd to start after X. Spacenavd is
supposed to automatically detect when the X server starts, and will
connect to the X server then. If this doesn't happen, then it might be a
bug or misconfiguration.

I assume this part of the log is from before the X server is started?

The way you restart it makes a difference when it comes to X
authentication. For instance if you do it with sudo as opposed to
becoming root first, so try restarting it from a diferent console
completely by logging in as root, to make absolutely sure it's not
related to X auth.

I'll try to reproduce the problem and get back at you, but this won't be
very soon I'm afraid. I'm extremely busy before the holidays. Until then
if you have any further details that would help, please post them.
