[FreeNX-kNX] x2go, pulseaudio etc

[brian mullan]

Nick

I switch a long time ago from FreeNX and also as a paid user of NX to x2go.

x2go is just a great remote desktop and comes with native clients for Mac,
Windows & Linux.

x2go implements its own "server" and clients.

There is a also a Python based x2go client called PyHoca.

All is Open Source

x2go audio (pulseaudio), printing, remote file shares etc. all work well
without tinkering and it was for me a lot simpler to install.

If you use debian or ubuntu the installation takes 5 minutes

*on server*

   1. sudo add-apt-repository ppa:x2go/stable
   2. sudo apt-get update
   3. sudo apt-get install x2goserver x2goserver-xsession
   4. then add all users to the x2gouser "group"
      - sudo adduser <username> x2gouser


*on linux client*

   1. sudo add-apt-repository ppa:x2go/stable
   2. sudo apt-get update
   3. sudo apt-get install x2goclient


only other thing you "might" have to do is edit your /etc/ssh/sshd_config
file to
match the following.. then restart ssh (sudo /etc/init.d/ssh restart)

*# Change to yes to enable challenge-response passwords (beware issues with*
*# some PAM modules and threads)*
*ChallengeResponseAuthentication yes*
*
*
*# Change to no to disable tunnelled clear text passwords*
*PasswordAuthentication yes*


some linux versions "may" have those 2 entries set to NO or commented out
(same as NO).

*Thats it !*

If you are on Windows just download & install the Windows version as you
would any other Windows app.
Mac is supported but I don't use a Mac so you'd have to ask on the x2go
Users mailer how to do it.

When you start the x2go client you create a "session"
it will ask you for:
IP address or DNS name of the x2go server
login ID
and you need to select what "desktop" you use (Unity, Gnome, xfce, lxde etc)

Click the "connection" tab and you will see a slider.  The purpose of that
is to tell x2go client/server
how much compression to utilize.

If you have a fast internet (I have 17 Mbps)... just move it all the way to
LAN.

then save the profile
Click the newly made "session" icon picture on the right
enter your password
answer the linux question about an "unknown server" and your desktop should
pop up.

*NOW... all that being said realize that with BOTH Ubuntu Unity and with
ANY Gnome system the following:*

Starting in Ubuntu 12.10 there is NO Unity 2D any longer
Starting with Gnome 3.0 there is NO gnome-fallback any longer

NO Matter WHAT remote desktop you use (NX, FreeNX, x2go etc) ... as far as
I know... NONE of them will be capable of support
Unity 3D or Gnome 3.0 remote desktops because BOTH of those will be using
HW video acceleration which as of now no solution is in place.

NoMachine's website has a notice about this as well.

So... that being said if EITHER of the above apply to you the choices are
stay with your distro where you can use Unity-2d or gnome-fallback.
-or-
use one of the other "desktops"  (lxde, xfce etc)...

For Ubuntu the 12.04 Long Term Support (LTS) release is good for 6 more
years so if you use that you can just select Unity or Gnome
in x2go and you should be good to go because x2go will auto-magically use
Unity-2D or gnome-fallback ... whichever is the case

I'm assuming x2go on Debian is the same because some of the core developers
use Debian.

Interesting...any particular reason?

Is x2go compatible with the other array of NX clients?  It looks like it
uses the same NX agent components, and since we use a combination of FreeNX
and the commercial NX offerings, I like the fact that one client will
(mostly) work with both of the servers.
