restricting x2go to published applications

I would like to set up an x2go server where users can use only one application; they shouldn’t be able to get
a full desktop session. I assume I would set up that application as a published application, but how can I
disable full-session logins?

Disabling sound

Hello,

Setup: RHEL 7 server with x2goserver 4.0.1.19-3.el7.

The server's syslog is receiving heaps of messages like this:
Aug 26 20:38:03 servername pulseaudio[11023]: [pulseaudio] main.c: User-
configured server at localhost:30004, refusing to start/autospawn

There's no need to support audio in this setup. So:
Can I server-side configure x2go to completely disable sound?

Use an usb mass storage

Hi !

I use thinclients (HP T620) with the embedded OS (HP ThinPro)
I install the x2goclient (4.0.1.1) on it.

My broker (ubuntu server 14.04, x2gobroker : 0.0.3.1) works fine and my 
server (xubuntu 14.04, x2goserver : 4.1.0.0) too (PPA nightly build).

I can open session trough winbind authentification and everything works 
well.

Next step is to allow the possibility of plugging a usb mass storage on 
the thinclient and connect it on the session wich is open on the x2goserver.

It is possible ? If yes, how ?

Thanks a lot for your anwer

Regards.

Questions regarding mate/video quailty

Hi everyone,

I have following szenario:
- server: Fedora 22 with gnome 3.16 (and mate)
- client cubietruck (mini client like raspberry)
- connected via 1Gb-LAN-cable
- using LAN quality and no compression (but I also tried 16MB-jpg with
no difference)

1) As I read in the docu, gnome 3.12+ is not supported, are there any
plans in the near future?
2) After installing mate on the server, I didn't see an option "mate"
on the client (4.0.1), only gnome, kde, lxde, xfce, so I choose "other
desktop" (don't know if it's called exactly so, cause I have a german
interface) and mate-session as parameter. Is this the correct way to
use mate?
3) And this is my main point: Working seems to be fine so far, but
when I start a video in mate (over x2go) it opens "parole media
player" (seems to use gstreamer) and it says: "gstreamer backend error
- Configured videosink video is not working". If I start videos with
vlc they come up but are really slow und showing only each 5 seconds
or so. If I use nomachine v4 they are not as fluent as if I sit in
front of my "server", but at least they are acceptable. I don't have
the gstreamer problems there. Is there something I can configure, does
someone know this problem? videos I tested with are h.264 encoded if
that matters.

Thanks in advance,
Harald

PXE x2go questions

Hello, I'm using PXE thinclient in a gigabit LAN for a GNU/Linux KDE session. I have a two questions/issues:

1) Which is the best compression method? There are a lot of alternatives like "4k-png", which one may I choose? and may I use the "LAN" option?

2) sometimes the "Shutdown system button" in thinclient, doesn't work. I press it but nothing happens.

thanks,

X2Go on multiple screen Windows system

I have used X2Go for some time, server is an openSuse 13.1 system, client is

a Windows system.   For now it is running Vista, I am trying to replace it with Windows 8 embedded (a HP thin client).

 

The Windows system has two screens.  I want to use screen 1 for Windows, screen 2 for a fullscreen Linux desktop.

So I configured this in the X2Go client.   (use whole display, select display number 2)

 

However, I find that it does not work reliably.  This already occurred on Vista, where it initially opens the session

in a window and then quickly switches it to fullscreen.  Unfortunately the initial small size is sent to the Linux session

which adapts by resetting the desktop size, then the full screen size is sent a fractional second later.  The result is

that my window placement is all messed up.

 

However, after switching to the newer Windows 8 the issue becomes more pronounced, the window now initially

appears on screen 1 which is slightly smaller (because of the taskbar) and is then moved to screen 2, at which

time the vxcsrv just crashes.   I can work around it by starting a new session but it will not be full screen, there is

an unused area the size of the taskbar.

The server also does not crash when I select Fullscreen as the display mode (without Xinerama), but then I get the

fullscreen mode on screen 1 instead of screen 2 as I desire.

 

I see nothing about these problems in the documentation, do other users see those issues and/or is there something

I am missing and can use as a workaround?

 

Rob

No Mate desktop?

Hi, 

I have just succesfully installed x2go 4.0.1.19, both server and client are Debian Linux machines.
According to the documentation Mate (which I run on server) is fully supported, however the drop-down
field Session Type on client has no Mate entry. How can choose it?

Thanks,
  Tad

Client folder sharing not working with Windows x2go client

I have checked the forum for similar threads, and applied the solutions given there, but it does not solve my problem.

The Problem:

I installed x2go server on a Ubuntu 14.04 VM running in XenServer 6.2.
Using LXDE desktop, installed LXDE desktop bindings.

Using regular Windows x2go client from Windows XP.
No problem to create a session and run it.

Added a shared folder for c:\Documents and Settings\Admin.
The shared folder does not appear in the x2go session.

On the server, using "df -h" to display the various disks gives the message:

df: '/tmp/.x2go-sysadmin/spool/C-sysadmin-50-1439738979_stDLXDE_dp16': Transport endpoint is not connected

sysadmin is the user name on the Linux Ubuntu 14.04 server used to log in to the session.
It is the default user of that installation, no other user created.

Curiously, when I re-issue the "df" command in the session a few times, the above error does not show again.
It only shows the first time, and only if I do not use use sudo to issue the command.
On earlier attempts, the path was different and contained "cygwin" somewhere in the middle of the path.
But there was also no folder to connect to.

What I Tried:

Client and server can ping each other. I can log in with putty (SSH) to the server. Therefore,
basic communications seem to be allright.

Tried to disable strict host key checking on the server in the ssh config file. No result.

Uninstalled desktop binding package and re-installed it a few times. No difference.

I also installed MATE desktop, and installed XFCE. Same result. I understand that XFCE has no
desktop binding package (if that package really has anything to do with that). At least, it did get
the exact same error.

At this point, I would need advice what I can check further, or what logs I can look into, as I do not know what to look for.

X2Go Centos 6 BROKEN


      I have a number of CentOS 6 boxes still in service.  Today one ate a disk
so I re-installed it.  But the X2Go RPM on ElRepo does not work, it's missing
a bunch of things that are neither present in the CentOS repository or the
ElRepo repository.  Even if I chase them down with rpm.pbone.net and install
the missing components it still doesn't work.

      I don't have time to troubleshoot further, I'm upgrading that machine
to CentOS 7, but someone might want to look at this as others may not have
that option because it will break something else.
