No button icons on Ubuntu 14.04

Hi,

updated a x2go server from xubuntu 13.10 to xubuntu 14.04 (64 bit) lately.

Now if I start a application (e.g. gedit) via x2go "application" session
there are no button icons shown.

If I start a desktop session and the same application within this
desktop session the button icons ARE shown.

Any hints?

nice article - Using WikID with x2go for 2 factor authentication

This just popped up on HowToForge as a new article post so I wanted to make others aware of
it:

Securing X2Go On Ubuntu Precise With WiKID Two-Factor Authentication

In this document we are going to demonstrate how to implement two-factor authentication from WiKID for remote desktop on an Ubuntu 12.04 server using X2Go. The WiKID Strong Authentication System is a commercial/open source two-factor authentication solution. X2Go is an NX-based remote desktop tool. First, we will configure a domain on the WiKID server, then add the targeted server as a network client to the WiKID server, and finally configure the Ubuntu Precise box for x2go using pam-radius. Note that if you already have a server configured as an SSH gateway box with pam-radius, you can simply add X2Go to and it will work.

Hi all,  Althoug this topic is some months old, I realy would like to ask Stephan
if he could elaborate some more on the >>self updating setup in the

Is it perhaps similar as the concept used by CoreOS as mentioned under
Technical Details on their page,http://coreos.com/using-coreos/updates/

x2go Broker more than one backend

Hi,
is it possible to use more than one backend with the broker?

Best regards,

screenshots while suspended?


I'm trying to create a local service which captures status screenshots
of a set of monitoring system windows about once a minute.

x2go seemed like it was working great to decouple the service from a
physical desktop, until I suspended the connection, at which point the
screenshots get wonky (mostly just grey with a little strip of actual window
contents along one border, or just all grey, or ...).  It works fine when
x2go is iconified, just not when it's disconnected.

Is this a known problem/feature?
I imagined Xclients wouldn't be impacted by a session being suspended or connected?

thanks.

x2go Broker

Questions over questions

Call from the client 
x2goclient - debug - broker-url = http://10.255.120.23:8080/plain/inifile 

8080 mean that a Web service must be running. but x2gobroker-daemon does not have port 8080 open. What do I need to?

x2goclient --debug --broker-url=http://localhost:8080/plain/inifile

An equal sign seems to be important behind --broker-url.

Please always reply to x2go-user and not only to my private address.

Make sure that your hostname resolves to a valid IP(v4 or v6) address.

Use /etc/hostname if you don't have a proper DNS setup in your lab.

SessionBroker

Hi there 
Questions about the Session Broker: 
Background: simple Session Broker Daemon 
x2go Server Ubuntu 14:04 - can be called directly from the client (Terminal works) 

1st Question 
x2gobroker-sessionprofiles.conf if I editable this file, I need to restart a service? 

2st Question
x2goclient - broker-url = http://10.255.120.23:8080/plain/inifile/ 

/ etc/x2go/x2gobroker.conf as standard out of the box 

SessionBroker Config: 
[pool-A server-A] 
user = visor 
name = GNOME - pool-A (srv-A) 
command = GNOME 
rootless = false 
acl-groups-allow = gnome-users, admins 
acl-groups-deny = ALL 
acl-clients deny = ALL 
acl-clients allow = ALL 
acl-any-order = deny-allow 
broker-session-autologin = true 

What is still missing the SessionBorker flies 

Thank you for your feedback 
Felix

Not Working with changes in PAM

Hi :

I was using x2go server and it worked fine until I follow this guide
in order to add my linux box (the x2go server) to a Microsoft Active
Directory ( https://help.ubuntu.com/community/ActiveDirectoryWinbindHowto
) , now I can't initiate a session from x2goclient to this box but can
do perfectly ssh sessions with Unix local users also mircrosoft
domains users, export X display works fine. Putting x2go server in
debug mode shows :

Also, at the client side (x2goclient), the error is :

Error: The remote NX proxy closed the connection
Error: Failure negotiating the session in stage '7
Error: Wrong version or invalid session authentication cookie
Session: Terminating session at .....

A popup message says :

x2go -51
The remote proxy closed the connection while negotiating the session.
This may be due to the wrong authentication credentials passed to the
server.

What do you think that can be happening? I can't understand. Any help?

Best regards,

Problems staying connected

Every time I login it works great for a few seconds, then it just freezes up. I checked the
.xsession-x2go-errors and this is what I see:

........................................................................
localuser:bitnami being added to access control list

(xfwm4:25785): xfwm4-WARNING **: The display does not support the XComposite extension.

........................................................................

If anyone can help that would be great. After three solid days of trying to make x2go actually work, it still
doesn't. I'm on a fresh Ubuntu 12.04.4 LTS (GNU/Linux 3.2.0-61-virtual x86_64).

Starting from there I did:

sudo add-apt-repository ppa:x2go/stable && sudo apt-get update

then

sudo apt-get install xfce4 xfce4-goodies xfce4-artwork xubuntu-icon-theme firefox x2goserver x2goserver-xsession

And that's where I'm at. If there is anything else I should do to make this work that would be great to know. It
usually crashes when I try to open up a folder or drag a window around. Sometimes I can't even get that far.

Any help is most appreciated... thanks...

Jon
