Re: [X2Go-Dev] Code formatting
by Dave Chamberlin-Kidd 25 May '20

Hi, Would it be worth considering cloud based GitHub, BitBucket or GitLab? All have free accounts available It'd save someone setting up and maintaining a server or image etc. Cheers Dave On Sat, 23 May 2020 at 11:00, <x2go-dev-request(a)lists.x2go.org> wrote: > Send x2go-dev mailing list submissions to > x2go-dev(a)lists.x2go.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.x2go.org/listinfo/x2go-dev > or, via email, send a message with subject or body 'help' to > x2go-dev-request(a)lists.x2go.org > > You can reach the person managing the list at > x2go-dev-owner(a)lists.x2go.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of x2go-dev digest..." > > > Today's Topics: > > 1.

x2goClient GUI code refactoring
by Dave Chamberlin-Kidd 24 May '20

24 May '20

Hi, I'd like to have a go at bug fixing, tidying up and adding features to the x2goClient and to start with I have spent a bit of time looking at the sessionbutton code to try to get to know it a bit. Having done so I think it would be useful to submit some refactoring patches. Once I've done this, I would then like to take the same approach with some of the other classes (onmainwindow being the next obvious candidate) This is the sort of thing that I can imagine isn't high priority for the core devs but it will, I think, make future improvements much easier to code, review and test. I don't want to stand on any toes so thought I would ask the following before submitting anything... 1: Is the above proposal acceptable? 2: If so is there a particular approach you would like me to take? (my plan is to start by extracting code into smaller functions in a series of small commits) 3: Do the dev team have any other thoughts/suggestions as to things they would like to see as part of a refactoring that I might be able to pick up Just to be clear, to start with my intention is to make the code easier to understand and follow without changing any functionality. Cheers Dave

Bug#1474: keyboard and mouse stop working after a few minutes of inactivity
by K. Kirsa 24 May '20

24 May '20

Package: x2goserver Version: 4.1.0.3-5 Ubuntu server 20.04 lts with xubuntu-desktop, installed on actual hardware, not a vm. No physical keyboard or mouse connected. After a while of inactivitiy (neither keyboard nor mouse are being used for a few minutes), the keyboard and mouse controls are lost. The session itself does not freeze: Windows with constantly updating contents or panel plugins still work. Resizing the x2go client window correctly resizes the remote xfce desktop. It's just like the keyboard and mouse are being disconnected somehow. It does not matter, if the x2go client (ms windows) stays connected or if I disnonnect and reconnect the client after a few minutes to resume the session: Keyboard and mouse even get lost during my "absence". The problem seems to be independent of the client. A new session suffers the same fate after a few minutes of inactivity. I disabled the screensaver and session locking in xfce settings. There's nothing I'm aware of happening in xfce that could act as a trigger for the keyborad and mouse loss. I searched the logs but did not manage to find any errors. Any ideas on where to look or what to try next? BTW: The same machine works perfectly fine with 18.04 lts, xubuntu-desktop and x2goserver.

Confusing Debian/Ubuntu versions
by Kees Bakker 22 May '20

22 May '20

Hey, The latest Ubuntu (focal) package has version 2:3.5.99.23-1build1. The first few lines in debian/changelog are: nx-libs (2:3.5.99.23-1build1) focal; urgency=medium * No-change rebuild for libgcc-s1 package name change. -- Matthias Klose <doko(a)ubuntu.com> Mon, 23 Mar 2020 07:21:04 +0100 nx-libs (2:3.5.99.23-1) unstable; urgency=medium * New upstream release. * debian/control: + Bump Standards-Version: to 4.5.0. No changes needed. * debian/nxagent.install: + Drop nxagent.xpm from pixmaps/ folder. Not shipped upstream anymore. * debian/rules: + Some extra quotes. Reduce delta between upstream DEB packaging and official Debian package. * debian/copyright: + Update copyright attributions. -- Mike Gabriel <sunweaver(a)debian.org> Thu, 30 Jan 2020 12:01:07 +0100 But debian/changelog in arctica/nx-libs (in the branch that was used for the release contains: nx-libs (2:3.5.99.23-0) unstable; urgency=medium * Upstream-provided Debian package for nx-libs. See upstream ChangeLog for recent changes. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Thu, 30 Jan 2020 10:59:43 +0100 nx-libs (2:3.5.99.22-0) unstable; urgency=medium * Upstream-provided Debian package for nx-libs. See upstream ChangeLog for recent changes. -- Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Tue, 27 Aug 2019 15:44:17 +0200 This is confusing. 2:3.5.99.23-0 is the latest from arctica, but Ubuntu focal already has 2:3.5.99.23-1. Mike, what's going on? -- Kees

Bug#1473: Cinnamon icon is loaded as a cog not the official Cinnamon logo
by Dave Chamberlin-Kidd 20 May '20

20 May '20

Package: x2goclient Version: 4.1.2.3 Severity: wishlist Tag: patch When the original code to load the Cinnamon icon was implemented it appears there wasn't an official icon. There is now. There is no error message as the code works as is but an incorrect icon is used for Cinnamon. This patch replaces the cog icon and removes the comment explaining why it was used. Cheers Dave

X2Go Client connection issue (Socket error)
by Melroy van den Berg 18 May '20

18 May '20

Hi X2go devs, Package: x2goclient Version: 4.1.2.2 (Linux Mint based on Ubuntu Bionic, using PPA) I often get an error message when I try to connect to my Debian buster docker image, running x2goserver and XFCE, via the X2Go Client on my host machine. It will give the following error message (when using the --debug flag on the x2goclient): x2go-DEBUG-../src/sshmasterconnection.cpp:2071> "ssh_channel_open_session failed": "Socket error: No such file or directory" x2go-DEBUG-../src/sshprocess.cpp:478> I/O error: "ssh_channel_open_session failed."" - Socket error: No such file or directory" (0). I created a detailed video, I posted it on YouTube, please take a look at the video: https://youtu.be/LAlLtBNTIUo Logging details, reproducibility and more is explained in the video itself. You'll notice that I can sometimes connect to the XFCE session and sometimes I can't. Although connecting via the ssh cli command is always working without any issues. Meaning there is really some kind of bug in the X2Go Client. I'm afraid. Again, I really hope somebody could help me in finding the root-cause and fixing the issue. Since I really love X2Go. And I would like to use this tool in production. I'm also a software developer so maybe I can help debugging the problem. Similar (same) bug is reported in the past (from 2019): https://lists.x2go.org/pipermail/x2go-user/2019-March/005512.html All the details regarding this Docker image and setup can be found in this git repo: https://gitlab.melroy.org/melroy/xfcevdi See attachments for additional debug logs of the client itself. One when successful and one during the error. Thanks in advance! Kind regards, Melroy van den Berg Ps. You can contact me by mail of course. But I can understand that debugging this issue would be preferable be done via VoIP for example.
