gpg --keyserver subkeys.pgp.net --recv-keys 4CC00851

Installing NoMachine NX on Ubuntu 7.10

NX allows you to run remote X11 sessions even across slow or low-bandwidth network connections, making it possible to start sessions from clients running on Windows, Linux, Mac OS X and Solaris platforms to servers running, at present, on Linux or Solaris. Note that development for extending server support to Windows and Mac OS X platforms is in progress.

NX, thanks to exclusive X protocol compression techniques and an integrated set of proxy agents, improves the power of the X Window System to transparently run graphical desktops and applications through the network, by reducing round-trips and implementing strict flow-control of data traveling through low-bandwidth links. Even on slow or low-bandwidth network connections, you can get impressive performance thanks to NX’s lazy encoding algorithm and NX’s capability to automatically tune itself to network bandwidth and latency parameters.

Moreover, NX also can connect to remote RDP and VNC servers, relying on the rdesktop and TightVNC clients by encapsulating the RDP or RFB session within the X11 session.

Here’s a screenshot:

Look at the screenshots below to find out how to get started with NX:

First download the files for the server from here.

For Ubuntu, use NX Free Edition for Linux DEB – i386.

You’ll need to download three files: client, node and server.

Change your working directory to the location where you saved the package and install it by running from a console:

For detailed instructions on how to install the NX Client, NX Node and NX Server packages, please look here.
sudo dpkg -i nxclient_3.1.0-2_i386.deb
sudo dpkg -i nxnode_3.1.0-3_i386.deb
sudo dpkg -i nxserver_3.1.0-2_i386.deb

After installing the server, on your Windows computer, download nxclient for Windows and install it.

Once it’s installed, run it, and enter the IP address of your Linux computer to connect, give it a session name for your own reference, and choose your connection speed.

Here you can download the manual or you can view it online here.

Prevent X.Org from Starting in Ubuntu

Prevent X.Org from Starting in Ubuntu

If you’ve got an Ubuntu machine that you initially installed with Ubuntu Desktop, but would like to run as a server, you can just disable the graphical
environment from starting up in order to save resources. This is also useful for doing system maintenance from the command line that needs to be performed
outside of the GUI.

The only reason to do this instead of removing the packages would be because you might want to still sometimes use the box through the GUI.

Disable X.Org

In order to disable the graphical environment, we’ll need to disable GDM, the Gnome Display Manager. In order to do this, you’ll need to run the following
command at the terminal:

sudo update-rc.d -f gdm remove

When you restart your computer, you’ll be presented with a text-mode login prompt instead of the graphical environment.

Run X.Org While Disabled

If you want to run the graphical environment, all you have to do is type the following command from the prompt, making sure to run it as your normal user
account.

startx

The annoying gray screen will go away once Gnome is fully started.

Enable X.Org

If you want to re-enable X11 it’s a simple matter of running this command from the terminal:

sudo update-rc.d -f gdm defaults

When you restart, you’ll be presented with the graphical prompt again.
