How to install FreeNX server and client in Ubuntu 9.10 (Karmic)

FreeNX is a system that allows you to access your desktop from another machine over the Internet. You can use this to login graphically to your desktop from a remote location. One example of its use would be to have a FreeNX server set up on your home computer, and graphically logging in to the home computer from your work computer, using a FreeNX client.

Installing the FreeNX server on Ubuntu 9.10 (Karmic)

Open your terminal from Applications->Accessories->Terminal

Run the following commands

sudo add-apt-repository ppa:freenx-team

sudo apt-get update

sudo aptitude install freenx

Now use nxsetup to install necessary files and create the special user "nx"

sudo /usr/lib/nx/nxsetup --install

  1. Take care if you run an vmware server 2 on the same machine. I can’t reach my webinterface after the installation of the free nx stuff

  2. Because NoMachine NX Server is limited and the full version is not free.

    FreeNX is a *free* NX server using the same NX libraries.

  5. @szamot83:
    This does not slow down the PC if no one logs in. If someone logs in, it uses as much CPU and memory as if the user was logged in directly.

    @Hissam:
    Use login and password of users which exist on the Linux system, exactly like when you log in directly on the Linux computer.
    You can connect from a Windows machine using NoMachine NX Client (free).

    You do not have to set a password for user nx. (It uses a certificate.).

    When you login using NX, you must use YOUR user login/password.

  6. NX doesn’t allow you to connect to your running desktop, but rather it initiates a *new* login. If you’re wanting to access another computer, to help with an issue, you won’t be able to see what the user is seeing. You will see a brand-new login; it doesn’t attach to the currently running display. Unfortunately, it seems that VNC is still the way to go, and unfortunately, the VNC server that comes with ubuntu (vino, dba Remote Desktop) has problems when you use the ATI or NVidia proprietary 3D drivers.

  7. Actually, VNC has no problems at all with the ATI/NVIDIA drivers – I’m using both (on different machines of course)

    The problem is with Compiz and its fancy graphics, which cause VNC not to see screen changes anymore. There’s even a bugreport about it that is several years old, but nobody cares to fix the bug.
