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

evince not snappy when displaying pdf, okular ok
by Denis Cardon 20 Nov '12

20 Nov '12

Hi everyone, I would like to have some input on which pdf software people uses on this mailing list. Evince (gnome2 pdf display software) is really slow and going through a pdf document can be a pain, even on 1Gib lan connection. Xpdf is also quite dragging. Okular (kde pdf display software) on the other hand is decently snappy, not as fast as local desktop, but yet decent enough for common users. However I'd like to stay with gnome2 (actually mate-desktop) environement. The issue was the same on debian squeeze with legacy gnome2. Scrolling through libreoffice 3.6 (with anti aliasing disabled) is fine. Firefox, which also draws its whole canvas, is fine too. So I think it is more a counter optimisation in evince/gtk-canvas than a fundamental problem. So if anyone has some input on this, I'd be glad to head. environement: * Debian wheezy 32bit * latest x2goserver and x2goclient * mate desktop environement (new name for gnome2 environement). thanks for your input, Denis -- Denis Cardon Tranquil IT Systems Les Espaces Jules Verne, bâtiment A 12 avenue Jules Verne 44230 Saint Sébastien sur Loire tel : +33 (0) 2.40.97.57.55 http://www.tranquil-it-systems.fr

Re: [X2go-User] Mac client 'Can't connect to X-Server
by Neil Hunt 14 Nov '12

14 Nov '12

Paul, Unfortunately as a regular user of the Mac X2go client, this is something I've seen many times. Unfortunately, I haven't found any fix for it. The good news is that it rarely happens if you keep the X11 application open. Always open X11 before starting your X2go session. From there, you can stop/start X2go sessions, even the X2go client itself, however I almost always keep my X11 app running even when it's not being uses and then I don't get the problem you are describing. If I quit X11, especially if it's accidental during an active X2go session, then I end up with the problem you are describing and the only option is to restart the whole computer. But if I keep it open, I go for days or weeks without rebooting. Ultimately, I think we should look to move to the PyHoca gui, but we haven't been able to find any serious python developers to port it to OS X. Neil -------------------------------------------------------------------------------------------- Date: Wed, 6 Jul 2011 12:14:51 -0700 From: Paul Northug <pnorthug(a)gmail.com> To: x2go-user(a)lists.berlios.de Subject: [X2go-User] Mac client 'Can't connect to X-Server' Message-ID: <CAJAeRZy=KmQsVyoELQ4MrTDHZ8g03x8tXJm_hTL5NK50jQ9QEw(a)mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Thank you to the developers for make this excellent software. Many people at my work use x2go's Mac client. We have never been able to figure out how to resolve the 'Can't connect to X-Server' error without random acts (eg. rebooting). We are not sure why it comes up. This is what I do: 1. Start X11.app 2. ssh -X remotehost 3. xterm & So far this works, I get an xterm so there is nothing wrong with X11 4. Start X2Go client 5. Start a session (port 22, dsa authentication, Gnome...) 6. Client gives the error and hangs (Abort and Terminate don't do anything) and I have to close the application. The closest we got to figuring it out is that the X11.app possibly changes it's DISPLAY on restarts and perhaps the x2go client is expecting display 0. Is there any more debugging information that I could get from the client to see what exactly it is doing prior to giving the error message? We have tried some of the suggestions in the forums, such as changing permissions in X11.app (this is necessary), starting it manually before starting the client. We have also done things like messed with firewall settings, made sure hostname doesn't change on our laptops between work and home, deleted preference files, delete XAuthority files, etc. What seems to work is rebooting. Thanks, P?l

Open GL dependencies
by Paul Daniels 10 Nov '12

10 Nov '12

I've got a kivy project that would work well with x2go. Running the program in a normal window works with open GL being reported as OpenGL version <2.1 Mesa 8.0.4> but when running on linux via x2go it reports as <1.2 (1.5 Mesa 6.4.1)> before segfaulting. Kivy apparently needs a newer open GL version. Can anyone give me, ANY, hints as to where I should go looking. Thanks, Paul Daniels

[X2Go-Announcement] New X2Go releases: x2goserver, x2goclient, nx-libs aka x2goagent
by Mike Gabriel 10 Nov '12

10 Nov '12

Dear all, The X2Go Project is proud to announce a couple of new X2Go core component releases: - x2goserver (3.1.1.6) - x2goclient (3.99.3.0) - nx-libs (incl. x2goagent, 3.5.0.16) All new packages are already available in our stable repositories (Debian, Ubuntu). The binaries for Windows / Mac OS of X2Go Client will follow ASAP. PING@: Mihai (Mac OS build?), Alex (Windows build?) In the new X2Go Server release several issues got addressed: o X2Go server now works with i18n ,,Desktop'' folder names (using XDG for detecting the folder name) o Prevent x2gocleansessions from leaving zombie processes behind In x2goclient, several new features have been added. We urgently ask to report back new issue that may have come up by this massive code change: o Native / local RDP client support (Linux only, use it on your thinclients!!!) o Encapsulate X2Go-proxied fullscreen RDP session in desktop X2Go sessions, not rootless anymore. => X2GO logo appears on screen after session startup of such an RDP session o Add SSH proxy and HTTP proxy support (HTTP proxy is only usable with a libssh version not yet released, so this feature won't work for most of you...) o Fix creation of desktop shortcut icons for launching individual session profiles in hidden mode o Fix broken Xinerama support (got broken when we fixed x2goclient being able to handle non-bash login sessions) o new desktop shell in session type configuration: XFCE o add package: x2goplugin-provider, shows an example plugin configuration (visit: http://localhost/x2goplugin.html) o Much work on the HTTP broker client code o SSH broker added to the client code o Fix x2goplugin (Failed to resolve hostname issue) o New translations: Spanish, Danish (Thanks to Ricardo and Christoffer!!!) o Updated translation files (thanks to the other translators, too!!!) In nx-libs the tarball installer has been improve. It now installs in the same way as is done by the Debian packaging intelligence (only difference, it installs to /usr/local). No configure script for nx-libs.git, yet, but hopefully we have someone (Ralf) working on it for some future release of nx-libs. People packaging nx-libs should thoroughly check their packaging mechanism!!! light+love, Mike X2GOSERVER ========== x2goserver (3.1.1.6-0~x2go1) RELEASE; urgency=low * Bugfix release (3.1.1.6): - Fix for non-well-tested x2gomountdirs script. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Wed, 07 Nov 2012 20:57:54 +0100 x2goserver (3.1.1.5-0~x2go1) RELEASE; urgency=low [ Stéphane Graber ] * New upstream version (3.1.1.5): - Add a very basic SIGCHLD handler to x2gocleansessions. on SIGCHLD let the script wait for cleaning up after its children.

Dependency Problem with x2go PPA packages
by Michael Nagel 09 Nov '12

09 Nov '12

Hi there, I am trying to install x2go from the Ubuntu PPA but I get the following error: ***** $ sudo apt-get install x2goserver Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: x2goserver : Depends: x2goagent (>= 2:3.5.0.15-0~) but it is not going to be installed E: Unable to correct problems, you have held broken packages. $ cat /etc/apt/sources.list.d/x2go-stable-precise.list deb http://ppa.launchpad.net/x2go/stable/ubuntu precise main deb-src http://ppa.launchpad.net/x2go/stable/ubuntu precise main ***** Any ideas what went wrong here? Best Regards Michael PS: I wrote a very similar mail to x2go-dev just before this mail. Sorry for creating noise, but I just discovered the different mailing list...
