Hi, Tim.

Sorry for the delay in getting back to you about NX, but it took me a 
while to work out what was wrong. I notice that you install 
"freenx-server", instead of "freenx", and that the indicator panel is 
missing. The terminal font is unreadable (overlapping letters) and there 
is no "logout" button. I worked around the font problem by editing the 
default terminal proble and installed "indicator-applet-complete" to 
provide a logout button in the top right corner. I've now got NX in a 
more-or-les workable configuration, but I'm concerned that this did not 
happen when I installed "ubuntu-desktop" and "FreeNX" on an Ubuntu 12.04 
LTS server instance manually (i.e. without your upgrade script).

BTW, I used my "dpkg-dsel" script to compare what your script installs 
in comparison to the 64-bit Ubuntu-desktop 12.04.1 LTS casper manifest.

HTH,

   Tony.
