community info here ( - looks like the freenx team has gone very very quiet since maverick. You could use the community info and try to install on oneiric. Tell us what you find out. – fossfreedom Oct 24 '11 at 23:12

sudo add-apt-repository ppa:freenx-team

sudo apt-get update

sudo aptitude install freenx

after that use nxsetup to install necessary files and create the special user “nx” type these "sudo /usr/lib/nx/nxsetup --install" and if you want to install opensource client for freenx use QTNX,QTNX NX client for QT install qtnx using the following command "sudo apt-get install qtnx"

I wrote a script to compile and instal freenx server on Ubuntu 11.10. See my blog:

What I ended up doing was installing the free Version of NoMachine NX Server, located hefer

The free version is limited to 2 sessions but I figured that should be enough to cover my needs right now. Thanks for your input.

I would recommend x2go. It's based on NX, but the server is incompatible with FreeNX and Nomachine. But it has things like PulseAudio integration, which makes it a little nicer to play with since you can then use VoIP, etc. Just add deb lenny main to your repos, update apt, and install x2goserver and then x2goclient on your client, from the same archive.

gpg: requesting key 96F89133 from hkp server gpg: keyserver timed out gpg: keyserver receive failed: keyserver error – Andre Oct 24 '11 at 23:55
They haven't signed it. Just ignore it and install it. It's generally a bad advise, but in this case.. Well. The world isn't perfect. :) – Jo-Erlend Schinstad Oct 25 '11 at 0:59
The X2go repository has migrated, use instead. – Lekensteyn Oct 25 '11 at 13:49
