Bug#1205: Unable to resume X2Go session
by Martin Stahlberg 16 Sep '17

16 Sep '17

Package: x2goserver Version: 4.0.1.20 Hello, I am experiencing the following problem, of which I am not quite sure which package causes it: I am trying to connect with an x2go client running on a Windows 10 system to a remote x2go server which I set up on a Debian Jessie 8.6 virtual machine (Kernel version 3.16.36-1), using XFCE as graphical interface. I am able to connect and establish a session, but if I suspend the session and try to resume it, the client closes the connection, and nothing works until I restart the server on the remote system. If I terminate the session and then try to open a new one, everything works fine. _X2Go version on server side (installed via apt from____http://packages.x2go.org/debian__):_ x2goagent: 3.5.0.32 x2golxdebindings: 1.0.2.4 x2goserver: 4.0.1.20 x2goserver-extensions: 4.0.1.20 x2goserver-xsession: 4.0.1.20 _X2Go client version:_ x2goclient: 4.1.00 _Content of the session.log when opening a new session, suspending it and trying to resume it: _ running as X2Go Agent NXAGENT - Version 3.5.0 Copyright (C) 2001, 2011 NoMachine.

I have tried also the following: - Accessing the remote machine from a different system (Ubuntu 16 with X2GoClient 4.1.01), with the same result - Using an external x server on the client side, with the same result So far, my guess is that this is some sort of authorization issue on the server side; the x2go installation on the remote machine was done using a fakeroot environment, although I have no idea how this could influence the resuming. I would be very thankful for any kind of advice! Best regards, Martin

Qt 4 to Qt 5
by rgregory 12 Sep '17

12 Sep '17

Hi All: Stefan asked if I would be willing to help porting some Qt4 projects (x2gclient and X2GoDesktopSharing) to Qt5. He gave me links to the git repositories for these two projects which I have downloaded and have build under Qt 5.9.1. There were only minimal changes to the DesktopSharing program and virtually no changes to the client system at all. So any way I've got a clean build of both. I have no idea of your testing regimes or code submission guidelines, so I'd appreciate someone letting me know what's next. Any ways, I'm glad to help. -rick -- Rick Gregory rgregory(a)gbgsoft.com www.gbgsoft.com 647-483-3488 800-413-3691

Bug#1200: Environment variables not set
by Bruno CAPELETO 05 Sep '17

05 Sep '17

Package: <x2goserver> Version: <4.0.1.20-0x2go1+git20170412.1125+9.main.1> # uname -a Linux mtcie1 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u1 (2017-06-18) x86_64 GNU/Linux The below bugs are most probably related to each other, that's why I open one case for all of them. The issues are the following : I want to use the French software Laurux, which is based on Gambas interpreter, via a x2go session running on a Debian 9 server running LXDE (same issues seen on an Ubuntu server, x2goserver version = 4.0.1.20-0~1125~ubuntu14.04.1).. As a prerequisite, the software is installed on the server and runs well on a local session. 1. Whatever the client (Windows or Linux 4.0.3.1-4), the local environment variables are not set properly and the software - which needs French localization - crashes. That could be "solved" the following way : /etc/x2go/Xsession : ... LANG=fr LC_ALL=fr_FR.UTF-8 export LANG export LC_ALL ... That seems to be a revival of older bugs, but it is definitely still here. 2. At the start of a new session, one gets a windows with an error message "No session for pid ..." ; that bug has already been reported several times in x2go bug tracking and marked as solved. Actually it is not on my brand new system. 3. The single application mode does not work with some of the applications, including that Laurux / Gambas. For example it works with /usr/bin/leafpad, but /usr/bin/libreoffice makes the x2go session crash. 4. The mouse double clic does not work in a x2go session, but only - within the Gambas software (works well for example when launching an application) and only - when the x2go client is running in a Windows environment (no problem when client in a Linux environment) Many thanks in advance for any support, Bruno

Bug#1201: Info received (Bug#1201: Acknowledgement (Black window with KDE5 plasma))
by Klaus Fuerstberger 03 Sep '17

03 Sep '17

I tested an KDE Neon LTS 5.8 (based on Ubuntu xenial) and KDE Neon 5.9 (based on Ubuntu zesty) on my system. With both distributions, nouveau and mesa glx is running fine. Also connecting with x2go to an x2goserver installed is no problem. After compiling and installing the mentioned latest NVIDIA driver, x2go fails again to launch KDE plasma. Klaus

Adding back the X2Go bugtracker, since this is valuable information for anyone that might hit this issue. On 09/01/2017 08:15 AM, J. M. van Bilsen wrote: > that would be sufficient to tackle the problem. You are right I have to > check if the package came from the mint or youre dist.

I'm happy to hear this. :) I still don't feel good just closing bug reports without any work carried out. More information: Linux Mint 18.1 seems to be based upon Ubuntu 16.04, and this edition has x2goclient 4.0.5.1-1 available (exactly), so this seems to be a hit. You're using very likely this version. So, now that we have this, I'm pretty sure you're also on libssh 0.6.3-4.3, which is naturally based upon libssh 0.6.3. The corresponding commit that introduced the SHA2-based MAC algorithms was 262c82ac0661bb0be46477006ed366e401c1620f (in libssh's source code repository.) This commit first made it into libssh 0.7.0. Older libssh versions do not include it and thus do not support SHA2-based MAC algorithms. Given that Ubuntu 16.04 only ships libssh 0.6.3, that explains your trouble. You basically have two options: either report this to Linux Mint and hope they will update the update the libssh package for you and rebuild every package that depends on it (including x2goclient), or build your own versions. The first one is not likely to be successful, though I do not know Mint's update philosophy. Debian and Ubuntu typically don't do such huge upgrades within a released version line. If necessary, changes are backported to the older version - but for libssh that might turn out to be quite complicated and not worth the effort. Mint might be different, so it might be worth a shot to try. The second one requires quite a lot of effort on your side, including staying up to date and deploying self-modified packages. Mihai
