x2godesktopsharing, what's the point?
by Marco Isella 03 Dec '12

03 Dec '12

Can someone explain me when I could use x2godesktopsharing? >From the doc it looks like you needed it to share a desktop but I managed to share desktops without installing it (I only in installed x2goserver). I made a small video to explain better the situation: http://bit.ly/TdpcxE I'm on Ubuntu 12.10. Second questions. With x2godesktopsharing installed I have an applet (http://bit.ly/TZosgs) in the systray where I can activate/deactivate desktop sharing but it has no effect (I can connect with a client when Deactivate desktop sharing is selected) and I don't understand how to add users (Granted user... and Banned users... are always greyed out...) Thanks Marco

Connection failed xhost: unable to open display "" on Windows 7 with x2goclient-3.99.3.0-pre3
by nigra truo 27 Nov '12

27 Nov '12

Hi, I have this problem with all newer versions of x2go on Windows 7. I have been trying to use a newer version than 3.01-4, but every time I do, I sooner or later get this error. Then I revert back to the old version and then it works flawlessly. Then, after some time, I wish to give a newer version a try and end up with the same problem, unable to use x2goclient. The strange thing is that I now used 3.99.3.0 for a week or so, without problems, but now I am stuck again, it just popped up out of nowhere. How can I fix this? It seems the vcxsrv is might not be started, but when starting it manually, it does not make a difference at all. Thanks, Markus

Message "Verbindung fehlgeschlagen Kann Datei nicht öffnen" when I start x2go-Client Windows
by tony.blue.mailinglist＠gmx.de 27 Nov '12

27 Nov '12

Hello, I use x2goserver 3.2 on my ubuntu-server (from http://ppa.launchpad.net/x2go/ppa/ubuntu precise main). On my Win7 (64 bit prof.) I installed X2GoClient 3.99.2.2. Always when I start x2goclient I get the error-Message "Verbindung fehlgeschlagen Kann Datei nicht öffnen". 1. What is wrong in my instalation? BTW: Like the description on http://www.x2go.org/doku.php/wiki:components:x2goclient#ms_windows1 I start with the parameter "http://www.x2go.org/doku.php/wiki:components:x2goclient#ms_windows1". But there is no shut-down button. 2. How get I a shut-down button? Thank you! Tony

python/gtk issues

So, it's me again :) I experienced something really strange for me. x2goclient:~% ssh -X x2goserver x2goserver:~% python Python 2.7.3rc2 (default, Apr 22 2012, 22:30:17) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import gtk >>> import gnome.ui >>> Everything's fine.

x2go & debian wheezy ... strange browser freezes (and other little problems)
by Tim Kruse 27 Nov '12

27 Nov '12

Hi list, I was in contact with Mike Gabriel and he suggested, that I post some issues to the list, so here I am ... We are going to migrate our Terminalserver-farm from freeNX to x2go and are heaviliy testing the new infrastructure. First I have to say, that x2go is running very good 'out of the box'. Our Test-Setup is as follows: 2 debian wheezy amd64 server (1 AMD Opteron 6128 6-core and 1 Core2 Quad Q6600 with 8Gb RAM each) connected through 1Gb Ethernet running x2goserver 3.1.1.4 (I know, 3.1.1.9 is the actual Version ...) and KDE 4.8.4 Both x2goserver are configured with Postgres Backend and we have an Loadbalancer with IPVS in front of them. x2goclient version is 3.99.3.0 and 3.99.2.1 In our productive environment we will have round about 700 users connected running an KDE4 DE in Kiosk mode using own coded Software (mostly Gambas2 & 3 and Python programs), libreoffice, okular and iceweasel/firefox. We experienced browser freezes with iceweasel 10.0.10 and firefox 13.0.1 after some time of browser-inactivity (>= 15 min). I didn't found any logentries (neither syslog or .xsession-x2go-erros on server nor on client) and the system load is normal ... The client, from which these freezes are observed is a Dualhead PC with nvidia graphic card running the x2go-session in fullscreen mode with xinerama extension and it seems, that the freezes do not occur on clients with only one Display attached. We have flashplugin-nonfree installed, no browser addons, but those freezes are not limited to any flashsites. They occur on several websites including 'normal' howto sites (eg. gambas helpsite) and phpmyadmin. The next thing I want to point out is up to sound (pulseaudio) and suspended sessions. If sound is activated an a user suspends his session, there is strange pulseaudio related logfileflooding. Every second I get: [pulseaudio] main.c: User-configured server at localhost:30014, refusing to start/autospawn. After saying that, I have to admit, that suspend is something we don't want in our setup. I linked x2gosuspend-session to x2goterminate-session to always terminate the session even if the client gives suspend as signal (thanks to Mike for the hint). I think thats it for now :) So long, Tim Kruse --

x2go session timeout
by Tim Kruse 27 Nov '12

27 Nov '12

Hi all, regarding some connection tests it turns out, that there is a 120 sec timeout, after which a session to a not responding proxy is turned into suspend mode. /tmp/$USER/session-C-$SESSID: Warning: No data received from remote proxy within 30 seconds. Error: No data received from remote proxy within 120 seconds. Session: Display failure detected at 'Mon Nov 26 16:39:07 2012'. Session: Suspending session at 'Mon Nov 26 16:39:07 2012'. Session: Session suspended at 'Mon Nov 26 16:39:07 2012'. So the question is, if there is a chance to change these 120s? I think, this is an x2go/nx-agent behavior, so where can we dig in? Next, is there a chance to change the default behavior to terminate and not suspend? Thx, Tim

Install not working on Ubuntu 12.10
by brian mullan 24 Nov '12

24 Nov '12

Joe I saw your post: https://lists.berlios.de/pipermail/x2go-user/2012-November/001107.html and wasn't sure if anyone responded to you yet. that error is caused by sshd_config file entry in Ubuntu which for some reason seems to change its default from release to release (at least for me). in /etc/ssh/ssd_config Ubuntu defaults to the following: # Change to yes to enable challenge-response passwords (beware issues with # some PAM modules and threads) ChallengeResponseAuthentication no # Change to no to disable tunnelled clear text passwords #PasswordAuthentication yes You will need to change: ChallengeResponseAuthentication no to ChallengeResponseAuthentication yes and uncomment the following by removing the Hash sign: #PasswordAuthentication yes then restart ssh sudo /etc/init.d/ssh restart also NOTE that for some reason on some Ubuntu upgrades I have seen the "PasswordAuthentication" entry have any one of the 2 following defaults 1. #PasswordAuthentication yes 2. PasswordAuthentication no Both of which make "PasswordAuthentication no" the active default. But with x2go if you want to use login with User ID and Password entry by a user on the x2go client you have to allow it (set it to yes). Brian

x2goclient shutdown button
by Saint Germain 23 Nov '12

23 Nov '12

Hello, I have freshly reinstalled x2goserver and x2goclient and it seems that I don't have a shutdown button anymore in the Gnome session to quit x2goclient session properly ? For the moment I just close the session by clicking on the close "X" on the upper right and everything resumes properly. But I was wondering if this is intended (was there really a shutdown button or was I dreaming ?). Thanks

German Keyboard Layout issue
by Michael Korn 20 Nov '12

20 Nov '12

Hello, I'm using Ubuntu 12.04 with X2go from the repository. If I work local, then I have no problems with the Keyboard Layout (de). But if I use X2go I have some issues. If I set (in Session preferences->Settings->Keyboard) Keyboard layout: de Keyboard model: pc105/de then I can't use the numpad correctly. If Num is unlocked, then it's fine. If I lock Num to use the numbers, then it works sometimes. E.g. sometimes I get '4' and sometimes the cursor goes one position to the left, if I press '4'. If I set (in Session preferences->Settings->Keyboard) Keyboard layout: auto Keyboard model: then the numpad works, but "AltGr", the arrow keys and "Strg" don't work correctly. Do anyone know the right configuration? Thanks, Michael
