In Ubuntu 7.04 I installed FreeNX like this:
1. Add repo in /etc/apt/sources.list:
deb http://free.linux.hp.com/~brett/seveas/freenx feisty-seveas freenx
deb-src http://free.linux.hp.com/~brett/seveas/freenx feisty-seveas freenx
2. Add key: wget http://free.linux.hp.com/~brett/seveas/freenx/seveas.gpg -O- | sudo apt-key add -
3. sudo apt-get update
4. sudo aptitude install freenx
Done. It has work!

I have upgrade to 7.10. freenx process works, but I can`t connect to remote desktop.

In NX-client after stage "Established a display connection" I have an error.

I have this error message in client (when press "Details" in login window):

I had the exact problem. I just removed freenx and installed the free nxserver from NoMachine (yes, they have a free version now). Just download from http://www.nomachine.com/download.php and follow the instruction. It works like a charm.

Simon, unfortunately free version of NX accepts only 2 users.
And I can`t run it correctly on upgraded system (NX server works only on clean Gutsy install but not on upgraded from Feisty to Gutsy)

Having the same issue on a Feisty upgraded to Gutsy:
Error: Connection with remote peer broken.

me too the same problem. I works in feisty after clean install gusty i can not connect to freenx server. is there any workaround? or a deb for the new freenx 0.7.1?

I tried to recompile it from the "source package" on the site:
Source (.dsc) nx_2.1.0-0~seveas2.dsc
Source (.tar.gz) nx_2.1.0.orig.tar.gz
Source (.diff.gz) nx_2.1.0-0~seveas2.diff.gz

and have the same problem - it doesn't work. The display with !M appeares and disappers in a moment. Here's what I have in nxclient log:

What about this:

It works in Feisty, but not in Gutsy.
And there are no FreeNX repos for Gutsy.

Did you try changing feisty to gutsy in the repos ?
The wiki is not yet updated to gutsy.

FreeNX repos is not yet updated to gutsy to.
I tried clean install from Feisty repos — FreeNX didn`t work.

Seveas repos is still for feisty not for gutsy i have tried to force it install it in gusty but client can not connect. any workaround????

The free version of NX Server from NoMachine works fine on Gutsy system that is an upgraded Feisty.

We just use it for accessing our work machines from home, so the 2 user limit is not a problem.

Derek Buckley, did you have installed FreeNX on 7.04 before upgrade?

Thanks alyandon, that solved my question.

In my post above, in step #2, "Edit "/etc/nxserver"" should be "Edit "/etc/nxserver/node.conf"". Sorry for any confusion.

alyandon: I did the following to get freenx working under Gutsy:

1) The nxsetup attempts to sanity check your config via nxloadconfig which fails because library names have changed:

Edit /usr/lib/nx/nxloadconfig and change line 266 to the following (all one line):

[ -z "$APPLICATION_LIBRARY_PRELOAD" ] && APPLICATION_LIBRARY_PRELOAD="$APPLICATION_LIBRARY_PATH/libX11-nx.so.6.2:$APPLICATION_LIBRARY_PATH/libXext-nx.so.6.4:$A PPLICATION_LIBRARY_PATH/libXcomp.so:$APPLICATION_LIBRARY_PATH/libXcompext.so:$APPLICATION_LIBRARY_PATH/libXrender-nx.so.1.2"

2) The font path in gutsy has changed so freenx can't find your install X fonts.

Edit /etc/nxserver/ and add (this is all one line with a space after "-fp"):

AGENT_EXTRA_OPTIONS_X="-fp /usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi"

This gets freenx working well enough for me under Gutsy. However, this IS NOT a proper replacement for a working gutsy package. If you want to see one you need to politely ask the maintainers to create a proper package and update their gutsy repositories.
=======================
Still got errors after following this help. However, I finally find it out.
There's one space in "$A PPLICATION_LIBRARY_PATH/libXcomp.so" ---> corrected "$APPLICATION_LIBRARY_PATH/libXcomp.so"

Thank you very much for your very useful help. ^^ .
Love Ubuntu and FreeNX ^^

Yeah, that's definitely some sort of copy/paste issue. Sorry about that.

alyandon, you are a gentleman and a scholar! I was so not looking forward to debugging that. Thanks for doing it for me. :-)

I had to change some libraries to libraryname.2 because I had them in second version.

I can't connect to server. I can login but after login nxwindow shows for 1 second and dissapers. I thinks it's beacuse of this:

Ok, nxserver is ready.

IIRC, you have to use the NX 1.5 or 2.x client when connecting to a freenx server.

FWIW - I did the font fix (*only*), and that was sufficient to get me back on the air.

Conditions:
Fiesty upgraded to gutsy

FreeNX fiesty repository enabled.

FreeNX removed, then replaced via synaptic.

/etc/nxserver/node.conf edited, and the above line adding the font directories added.

Whalla - it worked (for me...)

Hi,
I've got same problem : "Connection with remote peer broken.".
After that I tried to figure out reading your conversations and found a solution (for me):

my configuration:
Updated from 6.10 to 7.10 Gutsy Ubuntu.
Free NXServer and NxClient instead of FreeNX.

I only commented the line of AGENT_EXTRA_OPTIONS = "-fp /usr/share/X11/fonts........".

It worked.

Regards,

I solved the font-problem after my upgrade from Feisty to Gutsy with following commands:
  cd /usr/share/X11
  sudo ln -s ../fonts/X11 fonts

It's just another way of solving the same problem.
