Hi, When do you expect to release the windows client version 4.1.0.1 ? It fixes a very annoying bug with the PATH variable. https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1100 Regards, Martin

fedora 26 sessions do not resume
by Neal Becker 07 Aug '17

07 Aug '17

I've tried xfce and lxde. It seems on fedora 26 each time I try to resume a session it starts from a blank state - not resuming previous session. I did not have this issue with fedora 25. Any ideas?

x2godesktopsharing Connection error No protocol specified xwininfo: error: unable to open display ":0"
by Víctor J. Sánchez 01 Aug '17

01 Aug '17

Hi all, I'm trying to connect to an existing user session (local desktop mode) to help him in a remote host using x2godesktopsharing feature but I always get the next error (the first is in spanish): Error en la conexión No protocol specified xwininfo: error: unable to open display ":0" No protocol specified xwininfo: error: unable to open display ":0" The scenario is: - Remote host: Linux Mint 18.1 x64, Plasma 5 session, nopasswordlogin user and unprivileged (user A) logged in, X2Go Desktop Sharing running and enabled, administrator (sudoer) user B included in group x2godesktopsharing x2goversion: x2goagent: 3.5.0.32 x2godesktopsharing: 3.1.1.3 x2goserver: 4.0.1.20 x2goserver-printing: 4.0.1.20 x2goserver-xsession: 4.0.1.20 - Local host: Fedora 25 Workstation x64, Plasma 5 session x2goversion: cups-x2go: 3.0.1.3 x2goagent: 3.5.0.32 x2goserver: 4.0.1.20 x2goserver-extensions: 4.0.1.20 x2goserver-fmbindings: 4.0.1.20 x2goserver-printing: 4.0.1.20 x2goserver-xsession: 4.0.1.20 Client X2Go v. 4.1.0.0 (Qt - 4.8.7) I also tested on a local host with Windows 10 X2Go client and the error is the same. However other connection types (terminal or published applications) work fine. I've also tried with another remote sessions: XFCE, Cinnamon, ... the same result. Also I've observed that if the remote user A executes in a terminal window the "xhost +" command, when the user B connects to remote host with local desktop mode a window to choose a desktop is presented but only appears "non-existent" user B sessions (user B, screen :0) instead of user A session. What's wrong here? Thanks for your support. Regards.

New X2Go-ThinClientEdition-Live images available; changes to X2Go-TCE-Live build process
by Stefan Baur 28 Jul '17

28 Jul '17

Hi everyone, this is to inform you that new X2Go-TCE-Live images have been built and are available for download here: <http://x2go.baur-itcs.de/x2go-tce-stable/> All files have been checksummed with md5, sha1 and sha256, the resulting files have been clearsigned using my GPG private key. My GPG public key is attached to this message, so you can (and should) verify the integrity of your downloads. Everything you need to know about X2Go-TCE-Live can be found here: <http://wiki.x2go.org/doku.php/doc:howto:tce> The most important change is probably the one documented in this diff: <http://wiki.x2go.org/doku.php/doc:howto:tce?do=revisions> It allows you to query which versions of X2Go-TCE are installed/running, if you are using local storage/writable portable media in combination with the updateurl= boot parameter. This is really helpful if you are using some kind of monitoring software - now you can monitor update progress. Also, all log output from our custom startup/if-up scripts is now written to /dev/tty8 as soon as it becomes available, and once a network interface is "up", an attempt is made to sync time using the ntpdate command (at present, it uses the ntp servers that are used as defaults in Debian; the code could be expanded to use custom ones if required). Other than that, the current images now feature a colorful login message both locally as well as via SSH, where details like MAC and IP are highlighted, as well as various improvements to the update mechanism. Please note that there have also been a few changes to the X2Go-TCE-Live build process, so if you're using our scripts to build your own image, you should download current copies from the wiki: <http://wiki.x2go.org/doku.php/doc:howto:tce#configuring_the_build> <http://wiki.x2go.org/doku.php/doc:howto:tce#live-patching_the_build> <http://wiki.x2go.org/doku.php/doc:howto:tce#starting_the_build> Kind Regards, Stefan Baur -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243

Compatibility between x2go deb packaged versions
by Olivier BILHAUT 26 Jul '17

26 Jul '17

Hi to all ! I've got a x2go server 4.0.1.20 running on debian 8, and I am surprised that my x2goagent 4.1.0.0 running on debian 9 fails to connect to the server... The error message is : "Unable to create SSH tunnel : Connexion error on localhost:1000" Is there a way to maintain compatibility between versions ? What are the recommendations ? Thanks ! Olivier B

Mac Lion
by Robert Dinse 26 Jul '17

26 Jul '17

I've been using X2go on Ubuntu linux (client) and a dozen or so flavors of Linux servers without any great problems. I have to compile nx-libs myself on some of them to use the nightly build and not have resolution issues but otherwise all good. I recently setup my Mac with MacOS again (stil have Ubuntu, it is dual boot), and I can not get x2go to work under MacOS. It connects but just gives a black screen. When I connect to the same servers using Ubuntu no issues. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Why does X2Go spawn so many shells in single-application mode?
by Tristan Miller 26 Jul '17

26 Jul '17

Greetings. I'm trying to troubleshoot a problem where my PATH environment variable isn't getting set correctly when launching a terminal via X2Go. Perhaps this is a problem with the way I have my Bash files set up, but on the other hand it may be an X2Go bug related to Bug 149: <https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=149>. Anyway, to trace the execution path, I've added logging messages to all the files sourced by Bash. I immediately noticed that whenever I make an X2Go connection, four(!) separate Bash processes are spawned, not including the Bash process launched by the terminal itself. The parents of all four shells are the sshd process. By contrast, logging in on the console or via SSH results in just a single Bash process. Why does X2Go cause so many shells to be launched in single-application mode? Here are some steps to reproduce my logs, in case anyone is interested: 1. On the X2Go server, add lines such as the following to the beginning and end of /etc/profile and any other files that normally get sourced by Bash shells on your system (/etc/bash.bashrc, ~/.bash_profile, ~/.profile, ~/.bashrc, etc.): echo $(date) Entering /etc/profile $$ $PPID >>/tmp/login echo $(date) Leaving /etc/profile $$ $PPID >>/tmp/login 2. touch /tmp/login && chmod 666 /tmp/login 3. On the X2Go client, configure a connection to the X2Go Server with the "Session type" set to "Single application". For the command, choose /usr/bin/xterm or your favourite terminal emulator. (Note that /usr/bin/gnome-terminal doesn't work due to <https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=900>.) Then launch the connection and examine the logs in /tmp/login. Apart from the shell launched by the terminal emulator, you'll see four different shell processes were already launched -- the process ID and parent process ID are the last two fields of the log file. Examining the output of pstree -p shows that these shell processes are no longer running, and that their parents were all sshd. 4. Log in to the X2Go server again, this time from the console or via a vanilla SSH connection, and examine the /tmp/login file. This time you'll notice that the only shell process is the one you're in.

can't get x2g0 to work with wsl
by Troy Hall 21 Jul '17

21 Jul '17

Ok, I'm very confused.. I've installed just about every x2go item in apt search and still no go. I'm running wsl, fully updated and upgraded. I've tried numerous docs and steps to get it to work and it always says it can't timeout connecting to 192.168.1.137:8888 Can someone PLEASE help me figure this out. if I try the browser plugin it says "invalid plugin" here's the main thing I've been following, as you can see session.conf is not in /etc like he said it would be. Thanks in advance Bear
