Humm, apparently not available for *ubuntu, and universe is turned on.
root@shop:/etc/X11# apt-get install freenx
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package freenx
Installed it here with yum, but no manpages were included. Also, although
its installed according to yum, from the cli its all(freenx, nx) 'not
found', so I'm obviously not finding any setup help. Google seems to be
finding trouble threads only.
On one page I find a sample command line to start and stop the server, and
although it says its running, I don't see the correct effect:
root@shop:/# su gene
gene@shop:/$ cd
gene@shop:~$ cd emc2.head/
gene@shop:~/emc2.head$ scripts/emc
EMC2 - pre-2.1 CVS HEAD
Application initialization failed: no display name and no $DISPLAY
environment variable

The response is changed, but the end result is the same.
