I just setup another test from my Ubuntu laptop to a test Ubuntu VM
laptop running 12.10 and vm 12.04. Was able to connect no problem,
although I did forget and wondered why I started using XRDP instead,
NoMachine doesn't support Unity, so you will need to either setup Gnome
or Kubuntu etc. I think the next version of NX for Linux will support Unity.
Your problem though seems to be with authentication of a nx user, and I
remember something about this in the docs last time, just to be sure I
assume you are entering the username into the NXClient app on your mac
of a user on the Ubuntu machine? Otherwise take a look at this:
By the way, do you really need to use NX, what about doing what I did
and installing XRDP on Ubuntu and then running an RDP client from your
MAC, it's very fast... just not as secure, although I think you can also
set this up via SSH too.
