X2Go: The Gathering 2021 AKA "Over 9000!" (2021-12-03 - 2021-12-04) will be an entirely virtual event
by Stefan Baur 01 Dec '21

01 Dec '21

Dear $ALL, As stated in the subject line, X2Go: The Gathering 2021 - AKA "Over 9000!" - will be an entirely virtual event and will take place from Friday afternoon, 2021-12-03, to Sunday afternoon/evening, 2021-12-05. If you're wondering what the “Over 9000!” is about, take a look at <https://en.wikipedia.org/wiki/It%27s_Over_9000!> and at <https://experience.arcgis.com/experience/478220a4c454480e823b17327b2bf1d4>, especially the box titled “COVID-19-Fälle” (active Covid-19 cases), which is way over 9000. Under normal conditions, X2Go: The Gathering would be the annual event where users, admins, and developers (including the i18n volunteers) of X2Go, as well as members from the Arctica project and the orca e.V. nonprofit meet face to face, to discuss current X2Go-related issues, fix open bugs, and have a good time getting to know each other. Sadly, due to the ongoing Covid-19 pandemic, this year's X2Go: The Gathering will have to remain entirely virtual. Due to various reasons, we were unable to schedule the event earlier in the year, where Covid-19 infection numbers were lower and where meeting outside or keeping the windows open all day might have worked, so we're stuck with this late event date, which sadly coincides with the fourth Covid-19 wave here in Germany. This means we will be meeting via Jitsi and we will be live-streaming the event via YouTube. Links to the streams will be posted on <http://wiki.x2go.org/doku.php/events:x2go-gathering-2021> each day before the stream begins. You can join in any time, even on short notice, no sign-up required. We will be updating the Wiki page <http://wiki.x2go.org/doku.php/events:x2go-gathering-2021> as more information becomes available - especially the schedule, which is currently still in the works. We plan to release (at least) three new features for X2Go at or at least shortly after this year's X2Go: The Gathering, namely: - the HTML5 client - server-side X2Go-KDrive support, and - X2Go support in Remmina. The former two are currently already available via nightly builds, but we intend to declare them stable and turn them into a proper release. The latter should become available with the next Remmina release. Also, we intend to present the current state of X2Go-TCE on the Raspberry Pi. If time permits (and the individuals required for this are available for it), we will also attempt to move our bugtracker and git to our own gitlab instance (at least for new bugs). As this year's event is an entirely virtual event, there is not really a need for event sponsorships. However, if you're a company that had planned to sponsor the event, we'd appreciate it if you'd redirect the money to some paid work on X2Go instead. A list of companies/individuals available for this can be found here: <https://wiki.x2go.org/doku.php/doc:professional-support> If you're not sure what to sponsor - while the features already mentioned above are ready to be included in a stable release, they could still use some more love and affection. For example: - The HTML5 and Remmina clients don't support file and printer sharing yet - The HTML5 client also lacks sound support - The HTML5 client only works with KDrive, not "classic" X2Go-NX (to be honest, NX inside HTML5 doesn't really make sense since we are about to release KDrive as stable, but if you feel you have a good reason for it, let us know ...) - Remmina only works with "classic" X2Go-NX, not KDrive, and only on a client that still supports X11 (even though Remmina in general also works on a Wayland-only client) -> KDrive support would require a shared library for KDrive, either written in GTK or with more low level rendering toolskits (e.g. Glib-2.0 and Cairo, etc.). - KDrive probably needs some more work on the Windows (and possibly macOS) Client side. - X2Go-TCE on the Pi, while functional in general, still has some untested areas and is a little rough around the edges. - Also, we have been contacted once again regarding USB forwarding support in X2Go, so anyone interested in co-sponsoring this feature should speak up or at least contact me off-list - maybe we can get a co-sponsoring going, lowering the cost for all parties involved. And of course, you can also make donations, either in general or specifically earmarked for X2Go, via orca e.V. The entire schedule, save for the time and date of the orca e.V. meeting on Sunday, is still in a state of flux. We may move some presentations to a Saturday slot, depending on the availability of the speakers involved. If you would like to present something, please contact me via E-Mail (<mailto:X2Go-ML-1@baur-itcs.de>) and let me know the title of your presentation/talk, the expected duration and the times you would be available. Of course, you can also pre-record your presentation/talk if you want, but you will have to upload it to YouTube yourself and let us know the link (it may be unlisted, but must not be marked "private"). Sincerely, Stefan Baur, "X2Go: The Gathering" event organizer PS: Please heed the "reply-to" when replying, and make sure your reply gets sent only to <mailto:x2go-ml-1@baur-itcs.de>, as this message is sent to multiple X2Go mailing lists at once (and it is likely you are not subscribed to all of them, so your replies would clog up the moderation queue for the others). -- 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

Urgent: Increase disk on VM/Container
by Melroy van den Berg 01 Dec '21

01 Dec '21

Hi, Could somebody increase the disk on the VM/Container of GitLab (188.40.111.169). It causes a lot of IO performance issues. The '/' disk mount is now 100% full. Regards, Melroy van den Berg melroy89(a)pm.me

Bug#1571: Terminate session button selected by default on timeout
by Joe Dight 24 Nov '21

24 Nov '21

Package: x2goclient Version: 4.1.2.2 Tag: patch If the connection drops a dialog box asks to terminate the session or continue, with terminate selected by default. Continue should be selected by default. This doesn't seem to be intended (the constructor is called incorrectly), and the attached patch fixes it for me.

Package: x2goserver Severity: critical Unable to install x2Go packages for Debian because the repository archive key is not available. When I try to bootstrap the repository GPG keys using the docs: https://wiki.x2go.org/doku.php/wiki:repositories:debian with this command: apt-key adv --recv-keys --keyserver keys.gnupg.net E1F958385BFE2B6E Then I receive the following error message: GPG error: http://packages.x2go.org/debian stretch InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E1F958385BFE2B6E gpg: keyserver receive failed: No name It was working fine till last month. Please check if the public key has changed. I mark this ticket as critical because at the moment we are unable to even install x2Go for new users. Regards, Saion

Re: [X2Go-Dev] x2gohtmlclient, x2gowswrapper, x2gowebrpc

Hi tl;dr: x2gohtmlclient sends websocket input that nxagent rejects, then aborts on Debian 11 and Ubuntu 20.04.03; e.g. websockify records " var VNC_frame_data = [ '}3}6ba1f53e7eb3536232eeff332bd49336', '}3}\x07\x00\x00\x00\x00\x05\x98\x03\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 " nxagent reports Loop: WARNING!

I saw https://lists.x2go.org/pipermail/x2go-dev/2021-June/013764.html so I tried both Debian 11 and Ubuntu 20.04.03 but same failure on both. I'm new to x2go and the x2goclient works great so maybe this is an x2gohtmlclient et. al. issue? Perhaps this is a known issue or a misconfiguration on my part with a quick and easy answer.

by Mike Gabriel 18 Oct '21

18 Oct '21

Hi all, I have just updated X2Go's nx-libs (nxagent/nxproxy) version in X2Go's nightly builds repositories (aka X2Go heuler). There have been various improvements recently on nx-libs that need a broader test scenario. Here is a (reduced) list of pull request merged and issues resolved since last time we updated X2Go's nx-libs version.

vmlinuz, initrd and squashfs for netboot.xyz
by x2go-dev＠jugra.de 28 Sep '21

28 Sep '21

Hello together, after last messages on x2go-user mailing list I plan to try to integrate live-build-x2go into https://netboot.xyz/ I need place where we can place kernel, initrd and squashfs ~200M , so that it should not run to timeouts on another side of the earth. Maybe it's rational to make extra subdomain for it like boot.x2go.org and maybe mirror it to CDN. What do you think about it? Where would be the best hosting place for it? As a benefit x2go-users can use linux x2goclient if a main system is not running (or just for tests), but they have internet access and can boot floppy, cd, usb or just bootloader entry with netboot.xyz.lkrn (ipxe) or maybe netboot setup with tftp onside. On very modern systems it can be UEFI entry for httpboot. Best Regards, Juri Grabowski
