Thanks Richard [Doyle],
Ecstatic would clearly describe my emotional state when I VPNed into the district intranet, freenxed into the server, opened the Terminal in the gui that appeared, typed 'sudo reboot', and then a few minutes later, I was able to freeNX into that server and saw the beautiful Edubuntu desktop once again!
All I did was, (from this page: http://help.ubuntu.com/community/FreeNX):
Open your apt sources listgksudo gedit /etc/apt/sources.list
and append the two lines for the repositorydeb http://ppa.launchpad.net/freenx-team/ubuntu hardy mainI customized it to 'hardy' but any of the following that apply, work (it says): dapper, hardy or intrepid.
deb-src http://ppa.launchpad.net/freenx-team/ubuntu hardy main
Then I tried to:
But couldn't get passed the message that the keys didn't match or something upon doing step 2, above. So, I went to Synaptic (got that from another page), searched for 'freenx' and then selected the 'freenx' app for upgrade, applied it, ignored the security warnings, and installed it.
- Save and then close.
Then Update Apt sudo apt-get update
After you add the repository, then install the freenx package (using Aptitude to install extra needed packages). sudo aptitude install freenx
Then, I opened freenx, configured it (don't choose to disable the security encoding as it runs on port 22 and you will get an error message.) Then, I downloaded the client version for my mac laptop, configured it... and it worked :-).
One more barrier removed!
BTW--I recommend FreeNX to anyone using VNC currently, it looks a lot nicer and is smoother/more responsive.
