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.

User x2goprint - shell set to /bin/sh
by glpk xypron 09 Nov '12

09 Nov '12

Dear maintainer, on a system where x2goserver is installed I found the following entries in /etc/passwd: x2gouser:x:123:137::/var/lib/x2go:/bin/false x2goprint:x:130:139::/var/spool/x2goprint:/bin/sh Is there any reason why x2goprint should be able to logon interactively? Couldn't the shell be set to /bin/false like for x2gouser? Best regards Heinrich Schuchardt

Install not working on Ubuntu 12.10
by Joe Ambrosino 07 Nov '12

07 Nov '12

I have thus far installed x2go server on 3 Ubuntu desktop machines, two of them, Ubuntu 10.04 and one 12.04 that I've upgraded from10.04. The two machines that currently run on 10.04 work just fine I can connect using a password without using shared keys. I cannot get the 12.04 machine to work. I've installed & uninstalled completely several times. Each time I try to connect, I get an error -Access denied. Authentication that can continue: publickey, password,keyboard-interactive. I have tried connecting without a shared key, and discovered when I tried to use the shared key, the folder .x2go (yes I know, it's hidden) that is available in the Home folder on my other machines, isn't available on the 12.04 machine. I thought that perhaps the folder wasn't getting created because of a permissions issue, so I created an empty .x2go folder with the same permissions as on my other machines. This didn't help, the folder was never populated. I get no install errors. I tried enabling debugging, but wasn't able to find any output (I may not be looking in the correct place, but related is appearing in the logfile viewer.

Are logcheck rules for x2goserver available somewhere?

Dear list, logcheck includes many lines related to x2go programs in it's reports. Some examples are: Oct 29 10:15:38 remote /usr/bin/x2goterminate-session: session with ID XXX has been terminated successfully Oct 29 10:15:46 remote /usr/bin/x2gostartagent: successfully started X2Go agent session with ID XXX Oct 29 10:16:00 remote /usr/bin/x2gomountdirs[23127]: WARNING: mounting of /cygdrive/C/Users/___/spool failed Oct 29 10:19:04 remote /usr/bin/x2goresume-session: client <IP> has successfully resumed session with ID XXX Oct 29 10:19:13 remote /usr/bin/x2gomountdirs[9728]: WARNING: mounting of /cygdrive/C/___/spool failed Oct 29 10:19:32 remote /usr/bin/x2gosuspend-session: session with ID XXX has been suspended successfully Most of these messages indicate normal operation and shouldn't be reported by logcheck. This is usually achieved by adding a file containing a set of rules corresponding to messages generated by the server during normal operation in /etc/logcheck/ignore.d.* directories. Is such a set of rules available somewhere? Thanks in advance, Holger

run commands on the x2goclient
by Paul Daniels 05 Nov '12

05 Nov '12

Hi guys, I've been playing with X2go for a while now, and have a Thin Client Environment(TCE) that I PXE boot from, or copy to USB and boot via syslinux (after I've changed the initramfs.conf and regenerated the initrd so it boots locally rather than via nfs). But Although X2go works well, its still not fast enough for watching videos. My solution was to put mplayer on the TCE and pipe video to it at the moment with netcat, but Ill probably move to a multicast solution when I get all of the other issues sorted. So on the client I need to run the command netcat $SERVER $PORT | mplayer -display 0:0 - now whilst I can open up a console terminal, log into the x2goclient user and run the command, or write something that does the same it would be nice to run a command from within the x2go-session that does just that. Ive tried using x2goruncommand but it seems to kill of my currently running session. Is there a supported way to run a command locally, from withing an established x2go session, or do I have to code something up myself Thanks Paul Daniels

Translators needed (esp. French)
by Mike Gabriel 05 Nov '12

05 Nov '12

Hi all, the X2Go project is looking for someone who feels entitled to maintain the French translation of X2Go software projects (e.g. X2Go Client, PyHoca-GUI, ...). There currently is no French translation in X2Go applications and we would be happy to have that changed in the future. Please contact me via one of our lists or even privately. If you are interested in translating X2Go into your native language, please subscribe to this list... https://lists.berlios.de/mailman/listinfo/x2go-i18n ... and ask for further instructions there. Current translations looked after are: Englisch German Russian Svedish Norwegian/Bokmal Dutch (PyHoca-GUI only) Spanish Danish (X2Go Client only) So anyone who wants to start working on his own language is very welcome to the project (actually, everyone who wants to contribute to X2Go is welcome ;-) ).

session resuming after disconnect/reconnect
by richter＠ecos.de 24 Oct '12

24 Oct '12

Hi, when a session gets disconnected (e.g. network connection is lost, computer is powered down, without disconnect) I cannot simply resume the session after the next connect. I have first to pause the session, that wait a long time (don't know exactly how long, but needs to be more than 30-60 seconds) and than I am able to resume the session. If I simply pause/resume the session or try to take it over, the operation fails and the session is closed. Looks like after the pause of the old session, something does not get terminated correctly and needs to timeout before I can resume the session. Simply pausing/resuming a session works without problems, as long as the ssh session isn't closed in between. It also works if I pause the session, than disconnect the ssh connection. Than I can resume after I have reconnected to the server. Regards Gerald

ssh parameter?
by richter＠ecos.de 24 Oct '12

24 Oct '12

Hi, I am using PyHoca on Windows. Sometimes pyhoca disconnects from a server (while for example putty keeps connected to the same server). I guess there is some time out or keep alive that is too low, so the session gets disconnected, when the connection is unreliable. This there some way to configure the ssh parameters (e.g. configfile)? Also for some host the ssh host key has been saved and for others every time I connect I have to answer yes to accept the host key. Is there any way to tell pyhoc to save the host key? Thanks & Regards Gerald

Hi! I'm a new x2go-user. I tried to install a x2go-server which contains also a netboot image for many thin clients. I followed the documentation of the web page http://www.x2go.org/doku.php/wiki:components:tce I get a lot of errors. First of all I observed that the command x2gothinclient_preptftpboot generates a few files which are symlink to other files. These files are not visible by a tftp link (which is the initial step of a net boot). So I have changed the links with hard links. Furthermore the symlink are not corrected. They seem defined with respect the /opt/x2gothinclient/chroot directory. With the hard links the thin client boots correctly and the x2gothinclient program starts. But when I try to connect to my x2goserver I get an error message like this: proxy problem etc ... In the server side in the file /var/log/auth.log I get the following message When I use an installed debian distribution with the x2go client I get access to the x2goserver. Thank you in advance Best regards Stefano

Kde4 and Plasma Mess - Is anyone working with it?
by Helmer Teles 17 Oct '12

17 Oct '12

Hi dear, Fellows. i've been working with x2go for some time, but now i'm entrenched with KDE4 after many years with KDE3 running great with nomachine. KDE4 is still a mess nowadays. As anybody knows KDE4 has lots of problems with sizing and resizing of plasma panels, screen geometry and other stuff as usal. So i had to code lots of scripts that take use of x2goserver-run-extensions: What these scripts do is resize the plasma-panel and resize the screen geometry when resuming a session in case of the resuming is done in another Desktop or laptop with a change in resolution. My problem is that for plasma to assume the new resolution you have to kill it and start-it once again after you change plasma-desktop-appletsrc with the new values. So, when you do this after resuming the session, every time you move/maximize/minimize a window they slow to a crawl. How to test/reproduce this sympton. If you have a x2goserver installed with a kde4 session, kubuntu or other, start a session, go to konsole and do: kquitapp plasma-desktop && plasma-desktop & after plasma start if you try to move any window around everything will be allright and fast as before. After that do the same thing but after a x2gosuspend and in a runing resumed session try to move your konsole window around the desktop, it will lag like hell. If you this on a real display on your laptop, or in a running session everything will run fast as before. P.S: i'm sending this same email to both user & dev mailing list. Lab enviroment: Kubuntu 12.10 daily, kde 4.9.2 Best regards, -- Helmer Teles http://hteles.wordpress.com “Sent from My Linux Operating System” Please don't send me proprietary file formats, use ISO standard ODF instead (ISO/IEC 26300)

Compositing, Saving Sessions - xfce
by merc1984＠f-m.fm 16 Oct '12

16 Oct '12

I am not able to make compositing work in xfce. No transparency, shadowing, etc. Not even the needed settings. I'm thinking it has to do with this in .xsession-x2go-errors: xfwm4-WARNING **: The display does not support the XComposite extension. Is there some way I can make this work? Also my xfce sessions are not being saved when I terminate an x2go window. I suspect this is because X is crashing on logout before the session can be saved. Has anyone had this experience? In .xsession-x2go-errors: (xfce4-settings-helper:5597): xfce4-settings-helper-CRITICAL **: Your XI is too old (1.3) version 1.4 is required. ... ** (xfce4-session:5504): WARNING **: ICE connection 0x7fae284dce50 rejected ... And a ton of these: Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap" -- http://www.fastmail.fm - Email service worth paying for. Try it for free

In /var/log/syslog I can see that X2Go tries to mount client-side path "angel"@127.0.0.1:"/home/angel/desktop" at server-side path "/tmp/.x2go-angel/media/disk/_home_angel_desktop". Is it not strange that client has been resolved as 127.0.0.1 though it is a distinct machine from server? > If that does not help: what X2Go version do you have on the server > (run x2goversion command).

Output from x2goversion (server-side): x2goagent: 3.5.0.15 x2goserver: 3.1.1.4 x2goserver-extensions: 3.1.1.4 x2goserver-xsession: 3.1.1.4 Server-side distro is Debian squeeze (6.x).

Laptop to Server keyboard map doesn't work
by Will Rouesnel 16 Oct '12

16 Oct '12

I have x2go installed on a server system, a desktop and a laptop. All using 3.99.2.2, all running Linux Mint (Ubuntu variant). When I connect from the desktop to the server, the keyboard maps just fine - all keys work as expected. When I connect from the laptop to the server however, the keyboard map is messed up - home/end keys don't work, arrow keys map to other random keys etc. I cannot figure out why this is happening, and no combination of the x2go keyboard settings seems to change the result. I have noticed when connecting from the laptop to the server if I check the keyboard map when connected I get "null". Trying to change it results in an error from the keyboard daemon for changing the xkbmap. Is there anything I can do to try and debug this? It seems very odd that it goes so wrong from computer, but is perfectly fine from another, since the keyboards on both are configured to use the same generic 105-key layout.

x2gognomebindings package installation on ubuntu 12.04 fails
by Mark Dammer 12 Oct '12

12 Oct '12

I just installed x2go on a clean ubuntu 12.04 "precise" install. The installation of the package x2gognomebindings fails with an error. Luckily the workaround on John Wesoricks page works: sudo cp /etc/xdg/menus/gnome-settings-x2go.menu /etc/xdg/menus/gnome-settings.menu sudo apt-get install x2gognomebindings As the bug is known since November 2011 I would be grateful if whoever maintains the package would fix this. thanks a lot, Mark
