How to install Neatx (Similar to FreeNX) server on Ubuntu 10.04 (Lucid Lynx)

Sponsored Link
Neatx is an Open Source NX server, similar to the commercial NX server from NoMachine.
What Works

* Session creation
* Session suspension
* Session resumption
* Session shutdown
* Gnome/KDE/Application/Console sessions
* Floating Window/Virtual Desktop sessions
* Fullscreen/Resolution/Keyboard preferences
* Session shadowing (though only sessions belonging to you)

What Doesn't Work

* Terminating a session from the session list
* Windows/VNC sessions
* Sound, printer tunneling, Samba tunneling
* Local session sharing
* Load balancing

Install Neatx  server on Ubuntu 10.04

Open your terminal


and type in this command

sudo apt-get install python-software-properties && sudo add-apt-repository ppa:freenx-team

Then Update Apt

sudo apt-get update

At this point, the repository is added and apt is updated, then install the neatx-server package (using Aptitude to install extra needed packages).

sudo apt-get install neatx-server

    Hi. I have performed these steps, but am unable to connect to the remote machine via the NX Client for Mac. The client gets to “Waiting for Authentication” and then times out.

    Could someone point me in the right direction for help on this issue? Thanks a bunch!

    Make sure your firewall isn’t blocking your connection. port 22 (ssh) shouldn’t be blocked.

    I’d also highly suggest taking a look at x2go.

    Neatx still has key features that have yet to be implemented.

    x2go in its current release has clients for windows, mac and linux. the x2go server is not based on FreeNX or Neatx.

    x2go DOES use the NoMachine NX transport libraries so you get pretty much the same performance as the commercial NX… but x2go is open source.

    Also, x2go sound works 1st time, so does printing.

    x2go is expecting a new release this summer that will also include a “web portal” where all the clients will need is a Java Enabled browser.

    When Neatx gets audio, printing etc working I’ll take another look at it but in the meantime x2go works very well and is very easy to setup.

    find x2go at:

    It seems like they need to add binaries for Ubuntu 10.10 (Maverick) cuz those instructions don’t work for the install. Who supports the repository?

    The 10.04 Lucid versions still work in 10.10, although I’m not seeing title bars on Ubuntu windows in my Windows Vista client.

  8. Jorge says:

    The same here as defanso and Phildini… 🙁

  9. Viktor says:

    Simple fix for 10.10
    after following instructions do:
    nano /etc/apt/sources.list.d/freenx-team-ppa-maverick.list

    inside the file change maveric to lucid

    apt-get update

    all is well 😀

  10. DanielV says:

    Thanks Viktor, your simply solution works for me too 🙂

  11. Worked great. Got a thinlabs thin client to test with nx network login. Installed neatx-server onto my lan using your instructions and voila full gui exactly how I wanted it. Thanks

  12. Welber says:

    Steve. How did you get the thin clients? Did you use a OS like Thinstation? I’m curious. I’ve tried so many times, but with no success.
