NoMachine NX based

NX based

  • x2go was another company that build a open source product based on NoMachine open source libs. x2go: fast, polished, the best so far.

As for the different NX varieties: FreeNX is unmaintained, so is NeatX, and you forgot winswitch. When it comes to performance, which implementation you choose makes no difference since they all rely on the same NX libraries for remoting the display

NC Clients

OpenNX looks really nice. And uses libjpeg-turbo if it’s available on server.

RDP

  • FreeRDP is client, and their server is xrdp I tried it, and it’s not fast enough. But it’s simple to install. sudo apt-get install xrdp Connect to Ubuntu 12.04 (Precise Pangolin) via Windows Remote Desktop | Liberian Geek

    xrdp + libjpeg-turbo | Main / libjpeg-turbo

  • VRDP is a backwards-compatible extension to Microsoft’s Remote Desktop Protocol (RDP). You can use any standard RDP client to connect to such a remote virtual machine (examples follow below). For this to work, you must specify the IP address of your host system (not of the virtual machine!) as the server address to connect to, as well as the port number that the RDP server is using.

    I made it work, on port 5500 (not working on 3389 for me). But, it’s the same slow old VirtualBox speed.

Desktop Environment

I found great analysis of performance of Window Managers for Linux. The conclusions are simple: LXDE is the most lightweight. Then it is XFCE. Others forget.

Ubuntu - LXDE.org

There is even Puppet manifest puppet-ubuntu-desktop-install, with lot of other resources:

Linux/Unix (X) as an RDP (Remote Desktop Protocol) Server? | Carl’s blog

X11rdp is the name of the special RDP Xserver that is another part of the project, which skips out vnc altogether.

What xrdp with the VNC back-end is doing, is forwarding the VNC screen draws to your rdp client. The X11rdp back-end is an X server in its own right, and the screen updates will be that bit smoother and faster - and probably use less bandwidth than with the VNC back-end.

x11rdp « Scarygliders rdp - X11RDP Best Remote Desktop on Ubuntu 12.04 - Ask Ubuntu makinux-git/x11rdp-makinux · GitHub

SourceForge.net: xrdp:

I think you’re confusing two different things here.

X11rdp is a back end X server in its own right – think of it as something which paints the graphics onto a virtual screen which is in memory and is not sent directly to your graphics card.

xrdp, on the other hand, can be thought of as the bridge between that back end X server (X11rdp) and your physical display. When you use your RDP client (rdesktop on linux for example, or Remote Desktop client on Windows) , those clients talk to xrdp via the Remote Desktop Protocol (hence RDP). xrdp then communicates with the back end X11rdp X server, which sends its virtual graphics display to your RDP client, via the xrdp bridge.

The reason the back end X11rdp X server is not conveniently packaged up in a nice .deb, is because at the moment, it has been written in a way that makes it virtually impossible to do so. It’s currently written and attached limpet-like to an older version of the Xorg tree, and it’s a lot of work re-writing it to extricate it from that old tree and in such a way that it’s an independent module which can be easilly linked to the current Xorg tree.

That’s my current understanding of it anyway, and that’s why I try to write easy to follow tutorials on how to get X11rdp up and running as the back-end.

Notice if you install xrdp from the package manager, it also installs vnc? VNC is doing the job as the back end virtual display renderer, the output of which gets sent to your RDP client at the other end of the connection, via xrdp, as described above. The distros use VNC precisely because X11rdp is currently such a pain/practically impossible to package at the moment. But VNC is less efficient to use than the X11rdp X server because of the way it “draws” its display – that’s why I try to encourage use of X11rdp and write tutorials on it.

Also, the reason why I compile xrdp as well, is becuase to date, the distros are still using a slightly outdated version of xrdp which won’t talk to the latest versions of Remote Desktop Client for Windows – if and when a more up to date xrdp is included as a package, that step will become unnecessary.

Did you use the RDPsesman utility? That sets up your .xsession file for you ;)

Hopefully one of these days all my articles, tutorials and scripts related to X11rdp will become obsolete, whenever X11rdp finally becomes an independent module in its own right.

Hope that answers your questions :)

x11rdp is working like crazy! But, needs to be compiled.
