Humm, apparently not available for *ubuntu, and universe is turned on.

root at 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 at shop:/# su gene
gene at shop:/$ cd
gene at shop:~$ cd emc2.head/
gene at shop:~/emc2.head$ scripts/emc
EMC2 - pre-2.1 CVS HEAD
Application initialization failed: no display name and no $DISPLAY 
environment variable
Error in startup script: invalid command name "image"
    while executing
"image create photo -file $f/$i.gif"
    invoked from within
"if [file exists $f/$i.gif] {
            return [image create photo -file $f/$i.gif]
        }"
    (procedure "emc::image_search" line 7)
    invoked from within
"emc::image_search emc2-wizard"
    invoked from within
"set logo [emc::image_search emc2-wizard]"
    (file "/home/gene/emc2.head/tcl/bin/pickconfig.tcl" line 37)
Application initialization failed: no display name and no $DISPLAY 
environment variable

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