NX aims at providing stateful desktop sessions, similar to VNC, but with sound and requiring much less bandwidth. One NX implementation is FreeNX.

Install NX as an application

As a first step, create a connection from your local computer to your local computer, just to make sure it works:

• get the NX client, node and server rpm package from www.nomachine.com
• Install NX:

rpm -ivh nx*.rpm

• Setup NX:

nxsetup --install --setup-nomachine-key --clean --purge

• Start NX as root:

nxserver --start

• Verify as user root that the NX server is active

nxserver --status

• Connect to the NX server

nxclient --wizard

Continue as advised.

Now, to connect from a remote host, open the 500# ports in your target host's firewall. If you do not know how to do this, you can also shut down the firewall.

Install NX as display manager

Maybe you have a very old computer and want to make it a thin client to a faster one (the faster one acting as terminal server). Then you want the old computer to display the NX client program right after startup, without a user having to log in. So you want Nx to be your disPlay manager. Here are some changes I did to /etc/init.d/xdm to make this happen:

case "$1" in
    start)
        X &
        export DISPLAY=:0
        /usr/NX/bin/nxclient
        while true; do sleep 9; done

Tweaking NX

Almost everything is very fast and low-latency with NX. However, Window resizing effects are slow. Switch them off, e.g. in KDE using kpersonalizer:

kpersonalizer -> chose Next till you come to the Eyecandy-O-Meter -> Show details -> Window Moving/Resizing Effects
