Or you can use a session broker setup. However, there is no way of stopping a user that deliberately wants to mess with the configuration. They will always find a way to run x2goclient without any parameters/with their custom parameters, bypassing your restrictions. I guess the only way around it might (i.e., still no guarantee) be the HTML5Client in a rather elaborate setup, where users do not have direct access to the X2GoServer via IP, only to the HTML5Client.

Re: [X2Go-User] x2go for wayland
Hi Neal, Am 26.04.24 um 16:10 schrieb Neal Becker: I'm curious if there will be something like x2go for wayland. I've been playing with waypipe. It does appear to at least work for allowing a remote application running on wayland to be used on my local machine. Not sure if it performs as well on low-bandwidth connections as x2go using NX, but at least seems usable in some limited testing. What's missing is persistent sessions and remote desktop. While waypipe allows running a remote app, it doesn't AFAIK allow a remote desktop, nor persistence. A bit of googling found nothing useful. Anyone know if there is work in this area? Currently, we do not have any volunteer working on this, to my knowledge, and no paid developers, either. Unless Covid numbers play a prank on us on short notice, we'll be hosting X2Go: The Gathering 2024 at Linuxhotel Essen by the end of June. (A wiki page for the event already exists, the official announce will follow soon). I hope that we'll be able to discuss the future of a possible X2Go-Wayland-Integration at that event. My rough guess is that it will involve X2Go-KDrive, while NX will not be supported for Wayland connections. And yes, somehow merging waypipe with X2Go's session persistence features and client GUI is probably the way to go. As always: Sponsors welcome, patches welcome ...

[X2Go-User] Next Event/Upcoming X2Go and orca e.V. Sponsorship Drive - Starting Tomorrow, 2024-03-26, to 2024-03-28
Dear $ALL, X2Go will be present at Linux-Info-Day <https://www.luga.de/static/LIT-2024/> in Augsburg, Germany on Saturday, April 20th. At this event, we will have a booth where we will demo X2Go-KDrive, as well as the HTML5Client beta and X2Go's integration into the latest Remmina client. We're still waiting to hear back from the Linux-Info-Day crew regarding a talk slot - we have submitted a CfP for a talk regarding how to incorporate SSH, 2FA and X2Go into a simple, but effective Ransomware protection for vintage as well as current Microsoft Windows versions. If you're planning to attend and/or are in the area, feel free to stop by and say hi! Attendance is free, and you do not need to register beforehand. We are trying to cover the costs for our two volunteers/orca e.V. members (Mihai and me) via orca e.V., the registered association that X2Go belongs to, but for that, we will need your help in the form of donations*. Sadly, funding for X2Go events has tanked since we separated it from the main X2Go donation pool - we haven't received a single donation for our event budget yet. Which means that not only the trip to Linux Info Day is still in need of funding, but also the previous one to Linux Days Chemnitz. :'( The situation for our infrastructure budget is a little better, but we could use some help there as well. You can find our donation pages here: X2Go Events (English): <https://www.betterplace.org/en/projects/131360?wirwunder=235> X2Go Events (German): <https://www.betterplace.org/de/projects/131360?wirwunder=235> X2Go Infrastructure (English): <https://www.betterplace.org/en/projects/131358?wirwunder=235> X2Go Infrastructure (German): <https://www.betterplace.org/de/projects/131358?wirwunder=235> It would be really cool if you could send some $$$/€€€/£££/¥¥¥ our way, so we can keep advocating for X2Go and free remote desktop/remote application projects in general. We can accept donations via PayPal, Credit Card, Direct Debit, giropay/paydirect and wire transfer. Best of all, donations towards X2Go (and orca e.V., our umbrella org) are usually tax deductible for German tax subjects. Note that there is a special sponsorship drive sponsored by the Commercial and Savings Bank Ulm, where the orca (and thus X2Go) bank account resides: Projects receiving donations made between Tuesday, 2024-03-26 (starting 09:00 CET) and Thursday, 2024-03-28 (ending 23:59 CET) will receive additional funding from a pool of 10 000 Euro. So the more you donate during this timeframe, the higher the share we'll receive from those 10 000 Euro.

Re: [X2Go-User] x2goclient on windows
Hi Geert, Am 31.01.24 um 17:06 schrieb Witter, Geert: We want to use the x2goclient on windows. There is currently no download for the latest version and the 4.1.2.2 version seems to be unstable when starting connections. The 4.1.2.0 version looks to be working OK. Problem is that all versions have security issues, because some of the dll's (like libssh and OpenSSL) are outdated. Is it planned to have a windows release in the near future that has more up-to-date dependencies incorporated? We are currently severely understaffed on the volunteer side, so both Windows and macOS Clients won't see a release any time soon. For Windows, there is a "Beta" build that at least incorporates the kdriveclient. However, if you have a business use case, feel free to sponsor the work on these releases by contracting one of the companies listed here: <https://wiki.x2go.org/doku.php/doc:professional-support> Be warned, though, there is quite some technological debt involved, as no one bothered to sponsor work on this in the last few years, so this isn't going to be cheap, no matter which one of these companies you contract.

[X2Go-User] New Donation Options for X2Go/Upcoming Sponsorship Drive on NYE
Hi $ALL, One result of X2Go: The Spread 2023 was that we decided to re-organize our donation options. As before, you can make donations to orca e.V. (our registered nonprofit) and X2Go in general. However, now you can also make a dedicated donation towards X2Go's infrastructure or events. You can find the links to both the old and new donation options right on X2Go's Wiki frontpage: <https://wiki.x2go.org/doku.php> We are also investigating if we can use the platform to fund further development on X2Go, e.g. by putting up funding goals for certain features, but this will take some more time - first we'll need some legal counseling so as not to endanger orca e.V.'s non-profit status. And this legal counseling will have to be donation-funded as well ... Important: On New Year's Eve, 2023-12-31, all non-recurring donations up to 100 EUR will receive 15% on top from betterplace.org (donations above 100 EUR will receive 15 EUR on top, regardless of the amount), until the top-up budget of 8 000 EUR across all projects registered with betterplace is reached. This starts midnight 2023-12-31 CET, so the earlier you donate on that particular day, the higher the chances that your donation towards orca/X2Go will receive the additional 15%.

[X2Go-User] X2Go: The Spread 2023 - Recordings/How-To-Videos Now Online

So if you've never used anything but a complete remote Linux desktop via X2Go, or if you've never bothered to look at what other options than pxelinux exist for netbooting a ThinClient, you'll learn something new here.

[X2Go-User] X2Go: The Spread 2023 - You (K)Drive Me Krazy! 2023-12-11 to 2023-12-10
Dear $ALL, In exactly one month, from December 11th to December 15th, we'll have our annual X2Go meeting for users, admins and code contributors to X2Go - once again, 100% virtual/online, so it's a "The Spread" and not a "The Gathering" once more. We're hoping to see you there. We'll post a link to a virtual meeting room in due time, and expect to be streaming/recording the event to YouTube or a similar platform as well. Starting time will likely be 20:00 CET, as last year, unless a significant number of participants requests an earlier start time (say, 18:00 CET or 19:00 CET) - please let me know (off-list, see below for contact details) if you'd like to request an earlier start time. Sadly, in summer, where Covid numbers and weather conditions would have allowed for a real-life meeting, we had a scheduling conflict. And as the numbers are rising again, we cannot in good conscience host a real-life international conference - especially as some of our members have vulnerable household members or are vulnerable persons themselves. The event page (still work in progress) can be found here: <https://wiki.x2go.org/doku.php/events:x2go-spread-2023> Each evening has one, max. two time slots for a talk/presentation. At the moment, three topics are confirmed: - The usual "X2Go: State of the Union" opening speech - A report looking back at our latest stable X2Go release, which brought KDrive into the stable repository, and showing what still needs to be done Re: KDrive. - A report on how we used betterplace.org for collecting X2Go-related donations in the last 18 months, and an open discussion on how we could improve our usage of this platform. I am also hoping for a certain volunteer to commit to a fourth presentation regarding the latest changes and improvements in NX-Libs - since Arctica/NX-Libs pushed out a new release as well (on which our X2Go release is also based, obviously). This means we will have at least one more open talk slot - possibly more, if the two release reports for NX-Libs and X2Go only take 10-15 minutes each. If nobody volunteers, I might fill that remaining slot with a quick demo of how to netboot X2Go-TCE-Live via iPXE in EFI and legacy mode. But I'm really hoping for more volunteers for talks/demos/presentations - so if you would like to present something X2Go/NX-Libs/Arctica-related, please let me know (again, off-list, see below for contact details). We also have the option to prerecord your talk, in case your schedule doesn't allow for a live presentation and/or your internet connection is too flaky. It would be nice if you're available for a live Q round after your talk, though (via text-only chat or audio-only stream is fine). Please note that this time, the orca e.V. annual meeting will take place on the Sunday morning *before* the start of X2Go: The Spread 2023. All orca e.V. members have already received their invitation. To contact me, please do not hit "reply"/"reply to all"/"reply to list", but rather, send a *new* E-Mail to <mailto:x2go-m...@baur-itcs.de>.

Am 01.06.23 um 17:46 schrieb Enrico Baravoglia | Fucine.IT: PS Anyway Discover lists me tons of packets available for updates. There is not/any x2go packet listed anymore, as it happened two days ago. Would it be safe proceeding with that (huge) updates session? Well, if they're not x2go-related packages, I can't tell you for sure, especially since you didn't list their names (sorry, my magic crystal ball is currently undergoing repairs ;-)). What I would recommend is to run the following commands as root, or prefixed with sudo: apt update # just for good measure - should be current now ;-) apt upgrade -d -y # see explanation #1 below apt upgrade # see explanation #2 below #1 - as explained in the other thread, this will download all packages apt believes to be safe to install. It doesn't install them yet, so it is similar to using "-s", but with the added benefit that running the actual command later on will be quicker, as the packages are already there. #2 - this is the actual upgrade step. Review all packages carefully before confirming it. However, as this is "only" an "apt upgrade", not an "apt full-upgrade", you should be safe. Especially as long as you don't re-enable any X2Go PPAs for now. Avoid running "apt full-upgrade" or "apt-get dist-upgrade" and the like for now. Those are more likely to cause trouble, as they will trigger package removals and similar stuff that you should only be doing if you know what you're doing. Again, as I wrote in the other thread, "apt full-upgrade" is basically "Yes, do as I say!"'s little brother.

The neat thing about the first two is that they are free and don't require a hardware token - an free app on a Smartphone is enough. Also note that even though the first one is named after Google, it does not require a Google account, nor does it, to my knowledge, "phone home" to Google. Also, you can use any generic TOTP generator on the Smartphone side for both, you do not have to use the Google Authenticator app on the smartphone side just because you're using the Google Authenticator plugin on the server side. In fact, due to known security issues with it, I would recommend against using the Google Authenticator App on the smartphone side. However, the server-side plugin is really neat, IMO, and I would prefer it over pam_oath. It has some nice features like providing you with a bunch of back-up, emergency codes that you can print out and store somewhere safe. The one thing to remember is that you do not configure this in X2Go, but in SSH/PAM, as this is what X2Go uses to connect. If you can log in via SSH using your MFA key/token, you will also be able to use it for X2Go. There will be an additional Pop-Up after you've entered username and password where you need to enter/paste the one-time password. If X2GoClient doesn't show the popup, it is because the prompt (again, you can test/verify this via commandline SSH) doesn't match any of the known prompts listed above.

Re: [X2Go-User] x2go upgrade issues (packages with unmet dependencies)
Hi Enrico, I just tried to reproduce your issue. What Mihai (ionic) pointed out to me is that you had a mix of X2Go packages from Ubuntu itself and from the X2Go stable PPA. So I tried adding the stable PPA to an Ubuntu 20.04 machine that has been running X2Go stock from the Ubuntu repositories. I was able to add the PPA, I was able to run apt update, but when I tried apt install -d x2goserver x2goserver-xsession it started throwing errors already. But it did not break the existing installation. Trying apt full-upgrade -d I got a clear warning that several packages with x2go in their name would be uninstalled if I decided to continue. Sooo ...

Hi Olaf! Am 10.05.23 um 15:12 schrieb Olaf Staubus: I've been using x2go for a long time and I've always had the problem of jerky scrolling on websites. In the meantime, however, I use cloud services in the browser, and now another one is added. This is practically no longer usable with my x2go installation. Is there a combination (Linux OS + browser) that runs really fast? Videos aren't important, but modern websites shouldn't be stuttering. For classic, NX-libs based X2Go, you should use Pale Moon instead of Firefox or Chrome. If you're willing to run X2Go nightly builds, you can switch over to X2Go-KDrive, this should give you better browser performance for Firefox and Chrome. (KDrive should become stable Real Soon Now TM, but at the moment, it's only available via our nightly builds.)

[X2Go-User] The X2Go Project Could Use Your Help!
Hi $ALL, As Covid-19 restrictions are lifted all over the place, more and more events are taking place in real life again. Which means X2Go needs volunteers, equipment, and supplies for booths at such events. While we can't "buy" volunteers, we can do so for equipment and supplies - given sufficient funding. So if you want to support the project, you can chip in and help recover our costs. To donate to the project in general, click here: <https://www.betterplace.org/en/projects/111056?wirwunder=235> To donate towards a specific need, please use one of the following links: <https://www.betterplace.org/en/donate/platform/projects/111056?need_id=471564=235> - roughly 700 Euros should cover everything that was needed for LinuxDays Chemnitz 2023, we've already received 381 Euros, so we're only 319 Euros away from reaching our goal. <https://www.betterplace.org/en/donate/platform/projects/111056?need_id=484145=235> - roughly 200 Euros should cover everything that was needed for Linux Info Days Augsburg 2023. <https://www.betterplace.org/de/donate/platform/projects/111056?need_id=484152> - roughly 120 Euros should cover spare parts and labour costs to fix the keyboard of one of our demo laptops we use at events like the two listed above. All donations are tax deductible for German tax subjects. By the way: If you are unable to make a donation yourself, don't feel bad! You can also help us by liking/fav'ing this <https://twitter.com/farbenstau/status/1655513193966452743> tweet (which also boosts visibility on Twitter) and by retweeting it. Posting it on Facebook and other social media is also welcome and helps us, too. :) Kind Regards & Thank You For Your Support, Stefan Baur X2Go's Community Manager -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user
[X2Go-User] Upcoming X2Go and orca e.V. sponsorship drive - starting tomorrow, 2023-04-04
Dear $ALL, As you might know, a few years ago, at "X2Go: The Gathering 2017", several key members of X2Go as well as members from other Remote Desktop-/Remote Application projects joined together to form the Open Remote Computing Association - orca e.V. - a registered association under Germanys Civil Code and also registered as a charitable organization, similar to a 501(c)(3) organization in the US. In June 2022, we joined betterplace.org for easier handling of donations. They offer PayPal, SEPA Direct Debit, Credit Card, giropay/paydirekt and Wire transfer. And they also handle issuing donation receipts for us. (Note that while donations towards orca/X2Go are tax-deductible for German tax subjects, this may vary in other jurisdictions.) This is to let you know that the next sponsorship drive starts Tuesday, 2023-04-04, 09:00 CEST (that's tomorrow!) and ends Thursday, 2023-04-06, 23:59 CEST. It is sponsored by the Commercial and Savings Bank Ulm, where orca's bank account resides, and they are going to distribute 10 000 EUR among all charitable organizations registered with them via betterplace.org that receive donations in the timeframe above. So it's not a 1:1 matching of each donation, but the org with the biggest amount of donations gets the biggest piece of the cake, so to speak. If you can, please visit the donation sites below on one or more of the dates mentioned and send a few €€€ our way. (But don't feel bad if you can't. Times are rough. We get that.) We'd prefer if you use the German-language donation forms because with these, we know for sure that the donation counts towards the bank's pledge. However, if you're afraid of hitting the wrong button in a German-language form, feel free to use the link that points to the English version.

[X2Go-User] X2Go Booth at Chemnitzer LinuxTage 2023 - This Weekend!
Hi everyone! LinuxDays Chemnitz are taking place as a real-life event this Sat/Sun, and we'd love to see you there! We have secured both a booth for X2Go, as well as a handful of volunteers to staff it. If you want to support X2Go and our volunteers, you can chip in and help cover their costs for travel/lodging/supplies: <https://www.betterplace.org/en/donate/platform/projects/111056?need_id=471564> - roughly 700 Euros should cover everything that's needed.

[X2Go-User] HELP WANTED: LinuxDays Chemnitz 2023-03-11/2023-03-11 - X2Go could use additional booth volunteers
Dear $ALL, A lot of real-life events had to be cancelled in 2020-2022 due to the Covid-19 pandemic, some became online or hybrid events. In September 2022, LinuxDay.AT was the first to dare to return to a real-life event format. Now, LinuxDays Chemnitz is following suit: Their event takes place on the weekend of March 11th/March 12, 2023, in their pre-pandemic location, the Campus Reichenhainer Street of the Technical University Chemnitz. We have been able to secure a booth there, however, due to unforeseen circumstances, we are a bit shorter on booth staff than originally planned. So if anyone is planning to attend anyways, or at least considering to attend, please reply to this message (off-list, see Reply-To header). No promises, but we might be able to get you a free ticket in exchange for volunteering at our booth (this depends on the CLT folks' goodwill, as we're past the sign-up date). Also, we'll see if we can pick you up/drop you off somewhere along the route and see if we can get a room reserved for you as well. Again, no promises, as this is all very last minute and not going as expected, but we'll do our best. Note: There is no official mask mandate at the venue, but wearing a mask is strongly recommended. Assuming pre-pandemic attendance rates, you can expect 3600 visitors passing the booths in 2 days (opening hours are 8am-6pm on Saturday and 9am-6pm on Sunday). That is A. LOT. Which means the infection risk is way higher than on, say, public transport during a morning commute. Kind Regards, Stefan Baur X2Go's Event Planner & Lead Evangelist PS: The main reason for our booth volunteer shortage is that we were promised a mask mandate, but it has been dropped since. I was supposed to be one of the volunteers, but due to having a vulnerable household member, I will be unable to attend, given the higher risk. -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user
[X2Go-User] Three X2Go Spnsorship Drives: 2022-12-06, 2022-12-11 and 2022-12-18

They will be matching each non-recurring donation up to 100 EUR with the same amount. Also, all donations made on Sunday, 2022-12-11 and Sunday, 2022-12-18 will receive 20% on top directly from betterplace.org.

[X2Go-User] Two Upcoming X2Go Events: X2Go: The Spread 2021.5 and 2022
Hi $ALL, It's been a while, but now it is time for not only one, but two X2Go Events. As you all know, the Covid-19 pandemic kept us from hosting our usual X2Go: The Gathering events in 2021 and 2022. So instead of gathering, we'll now spread out. Instead of meeting for a weekend in "meatspace", like we used to, we'll now meet online during the work week starting 18:00 CET/MEZ each day (or possibly even later, given volunteer feedback), and only for a few hours each day. X2Go: The Spread 2021.5 (2022-11-28 to 2022-12-02) is the replacement event for X2Go: The Gathering 2021, which had to be cancelled due to illness of several core members. This event starts in a little less than a week - but if you can't make it on such short notice, do not worry. X2Go: The Spread 2021.5 will be more of an informal virtual meetup, with people working on "behind the scenes" stuff, testing out our streaming/recording equipment, etc. The "real deal" will be X2Go: The Spread 2022, which is also scheduled for the evening hours, but will take place from 2022-12-12 to 2022-12-16 (with a possible extension to one of the weekends before or after - we'll see). This is where we'll also have the annual orca e.V. meeting. The date and time for the orca e.V. meeting is fixed: 2022-12-16, 20:00 CET/MEZ. This is the event where we'll see/hear a talk each evening, and work on getting our releases out. Of course, both events have their own wiki page to track progress and updates: X2Go: The Spread 2021.5: <https://wiki.x2go.org/doku.php/events:x2go-spread-2021.5> X2Go: The Spread 2022: <https://wiki.x2go.org/doku.php/events:x2go-spread-2022> Kind Regards, Stefan Baur, X2Go's Event Planner -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

Be warned that the HTML5 client is currently not for production use, it is merely a proof of concept. That's why it is currently only available via nightly builds.

You will need to add the heuler repository there, too, as described at the very top of this message, and follow up with a "sudo apt update". That should leave you with a webserver publishing the X2Go login page, but only on 127.0.0.1. Port 80 redirects to 443, which uses a self-signed certificate. Once your local tests have been satisfactory, you can replace the cert with an official one belonging to your org, and start adding additional listening IP addresses to the /etc/nginx/sites-enabled/x2gohtmlclient-demo.conf file.

Re: [X2Go-User] Questions regarding features and configuration advice of X2go
Joerg, In short: forget about it. If you're allowing users SSH access for X2Go, they WILL be able to copy data. You can make it a little harder for them if you think you have to, but as long as they are in control of the client hardware, they will always be able to do so. X2Go is great to stop accidental copying when properly configured, but intentional copying - no. Also, remember that keyboard input can be scripted and redirected to a file on the server, and screenshots can be OCR'ed on a client, or people can convert your data into QR codes on the server and screenshot and scan those. So even if you'd use VNC and disable the clipboard there, you'd still not be safe from intentional copying. Decades ago, in a lawsuit, a judge defined a computer as "a machine to copy ones and zeroes", and to be honest, that's what it does. If you want to try to stop it from doing that, good luck. -Stefan Am 20.12.21 um 12:08 schrieb Jörg Kastning: > Dear X2go users, > > I'm trying to figure out whether X2go is a fitting solution for our > project or not. > > Users should get remote access to a host to execute applications in a > graphical environment.

Dear $ALL, I am very sad about this outcome, but we will need to cancel X2Go: The Gathering 2021 this weekend and need to postpone it to a later date. We currently have two core members that have become unavailable due to illness, another core member is likely unable to make it due to connectivity issues while being on the road. So, sadly, hosting the event on this weekend does not make sense. The same applies to the ORCA meeting that was planned for Sunday.

To me, your description sounds like you're using X2Go to mirror the local display. I'm not quite sure if that is supposed to work with no one logged in; my guess is that the behavior you are seeing should be considered "works as designed". You should always be able to run a native X2Go session (by selecting the name of the Desktop Environment you want to use in the X2Go Session Configuration). This will also be faster than mirroring, allow audio and clipboard forwarding, as well as file and printer sharing. Please post a screenshot of your current session configuration in X2GoClient if the problem persists.

[It's "X2Go", not "X20Go"] I'm not sure what Zoom is doing there, but an easy workaround might be to run the Zoom client on the workstation, while using X2GoClient in Published Application Mode rather than with a full remote Desktop Environment. That way, you might be able to share individual remote application windows, because there is no remote desktop that Zoom might accidentally capture. Another option you could try is their web client, from a web browser inside the X2Go session - not sure if the web client allows sharing a window, but might be worth a try.

Yes, that's because some of the applications we need to bundle with X2GoClient.exe are "stupid" and insist on binding to 0.0.0.0, where binding to 127.0.0.1 would suffice.

You can safely deny listening services on anything but 127.0.0.1 by adding such rules manually beforehand. The only exception would be pulseaudio, if you insist on *not* tunneling that traffic through SSH. While X2GoClient does offer that option, tunneling through SSH is enabled by default and I am not aware of anyone using it in "disabled" mode. By the way, are you aware that you can run X2GoClient via a read-only network share? That way, you don't have to push updates to the individual PCs - update your central installation on the network share, once, and you're all set.

If it's not too much of a problem for you, you could also try out upgrading your server to the development version of X2GoServer and try running X2Go in KDrive mode (this only works for Desktop Environments, not for single/published applications, though).

Aside from account sharing being bad security practice and a bad idea in general, yes, some desktop environments will be more suitable than others for this. Of course, running X2GoClient in Published Application Mode (with --autostart to start the desired application right after the X2GoClient's login to the X2GoServer) would help avoiding this problem altogether, because then no remote desktop environment is involved, but this mode comes with autoresume enabled by default, meaning, if there is exactly one session in a suspended state, this one will be resumed instead of a new one being created. To avoid this, you can run X2GoClient with --no-autoresume as an additional parameter - then it will always prompt you if you want to resume or create a new one if at least one suspended session is detected.

This may or may not be related to your issue, but as a hint, normally,
you do not need to start a separate SSH tunnel using ssh -L - that
function is included in X2GoClient.
The option you're looking for is in the session configuration:
Click the three bars ("hamburger icon") in the lower right of your
session tile, choose "Session Preferences" from the context menu.
On the Tab titled "Session", in the Section "Server", there is a
Checkbox "Use Proxy Server for SSH Connection". Check that and some new
options to choose from will appear.
There, select Proxy Server Type: SSH
The rest of the new options should be self-explanatory.
Kind Regards,

It sure is the right place to ask, but I hope you don't mind *me* asking a question first: Are you aware that there is another way of setting up X2Go-ThinClientEdition that does not need NFS?

As the name says, that's for Desktops, not for single applications/published applications. So I'm not surprised that gets you one window that all the others are confined to, and thus doesn't work for you. For "Single Application", I doubt that passing parameters is supported - so please try something like /usr/local/bin/mytestscript.sh # no "xterm", no "-e" in front of it instead of xterm -e /public/shell/radiossh with /usr/local/bin/mytestscript.sh containing #!/bin/bash xterm and chmod 755 that file. If that works, try expanding it with, say, #!/bin/bash xterm & xterm & xterm which should open three xterms with one single connection, or with #!/bin/bash xterm -e /public/shell/radiossh I know that some applications have a tendency to close their windows too fast again (thus triggering X2Go's session termination detection prematurely), which is why single application mode may not be what you want. So if you're still seeing issues, please try single application mode with a command line window (plain xterm), and running your command from there. If that works, but directly starting it does not (not even with a shell script as listed above), then we'll need to go down the Published Applications & Autostart route. -Stefan -- 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 signature.asc Description: OpenPGP digital signature ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

Well, they do have the desired effect for me, so it seems something's going wrong on your end. Maybe you reconnected to a suspended full-screen session (in that case, your initial selection of PubApp/SingleApp will be overridden)? Please make sure your user does not have a running or suspended X2Go session, then verify you selected "Published Applications" and closed the session configuration using the "OK" button, then verify the new session you are starting is the one you configured for PubApp mode (I would suggest using a descriptive session name to avoid any confusion).

Please select "Published Applications" for a remote start menu users can select applications from (you can select one application to start automatically even with PubApps, by passing the corresponding command line parameter), or "Single Application" for a single application that you want to share. -Stefan -- 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 signature.asc Description: OpenPGP digital signature ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

I think we have received previous reports about commercial Firewalls/SSH Gateways causing problems, but am unable to find that in the archives. When you log in to that jump host, is there any way to find out what it is running? Like, Linux, some BSD, or something commercial/closed source? Can you run commands like "uname -a" there? > I experimented with different speed and compression settings, also tried > to disable audio forwarding and printing but that did not change much. Well, as long as you're not actually using audio and printing, those connections will just sit there idle, so that is to be expected. > I can live with establishing that ssh proxy connection manually, but I am > still > a bit confused that even now the comparison with VPN is still showing VPN > as being > faster. Have you guys tested this and got consistent results which shows > the opposite? Oh, so you have the option of using a VPN connection instead of going through that jump host? In that case, it would be interesting to see what happens when you set up a jump host of your own (preferably based on Debian Buster) on your internal network (i.e. in the same network where your X2Go Server resides). If you can connect via the VPN to the Jump Host under your control, and from there to the X2Go Server, and it feels almost as fast or just as fast as connecting directly to the server (via VPN), then that would be an indication that your "official" jump host is having issues with our client. If, on the other hand, you're seeing the same lag again, it would mean that something's broken on our end, i.e. in X2GoClient. > Once I have more time on my hands I will try this with different machines > and > connections I have plenty where I could try this out. > > Completely different question: the way this works, would it in principle be > possible to > also have a windows client?

Well, X2GoClient allows you to set the DPI for your session (third tab in the session config), and it also allows you to enable or disable XINERAMA there. Maybe that helps?

I wonder if maybe our code for that is broken somehow? Is that ssh proxy/jump host a Linux machine or some proprietary solution? Could you test by setting up an SSH connection first, like so: ssh -p 22 -L:[targethostname]:22 johann@ssh.[somehere.org] After that connection has been established, please create a new X2Go session configuration (_don't_ alter the existing one) that connects to localhost:, without setting an SSH proxy, with XFCE as your DE, and using your "johann" account, but leave all the other options set to their default values. Then try to use that. Does it change the speed/responsiveness in any way?

This sounds very wrong. On the other hand, it is hard to debug without further info. Please provide us with the following: - Client OS and Version - Version of X2GoClient (Help/About X2GoClient) - Session configuration (preferably the "sessions" file/registry entries, rather than screenshots) - Server OS and Version - X2Go package source (your distribution's standard repo vs. X2Go's stable repo vs. X2Go's nightly repo) - Version numbers of all X2Go/NX-related packages (on Debian-based distros: dpkg -l | egrep "x2go|nx" ) - Available Bandwidth and type of network connection (WiFi, LAN cable; mobile network like UMTS/LTE, ...) By the way, if you want to basically disable X2Go compression etc. completely, Connection Speed "LAN" and Compression Method "nopack" are the options you are looking for.

X2Go uses SSH underneath, so whatever you can use with PAM (Pluggable Authentication Modules - <https://en.wikipedia.org/wiki/Pluggable_authentication_module>) will/should work with X2Go as well. We even support a handful of 2FA authentication methods. I know that there are PAM plugins for LDAP and AD, so getting this to work in your environment will most likely depend on the availability of these plugins for your specific Linux distribution, and require a more or less thorough study of the PAM syntax.

You are actually the third to encounter this issue; sadly, the other two couldn't be bothered to subscribe here to report the bug. It seems to be a server-side issue, using Ubuntu 20.04 on the server side is the common part of the reports. I wonder if maybe there's some kind of sleep/suspend/energy-saver at work, or maybe some kind of "scrubbing" mechanism (possibly systemd-related)? I've seen such issues in the past, in different contexts, where cron jobs were unaware of a running X2Go session and did "stupid" things (like shutting down the server) that affected the session - because to them, it looked like there are no users logged in. Do you think you could set up a test server with Ubuntu 20.04 that does not have a GUI, and only some very basic X applications like xterm? Is gdm (or some other graphical login manager) running on your server? If so, could you stop it, switch the machine to text-only mode, and see if that makes a difference? -Stefan -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

Maybe it would make sense to contact them directly and see if they've had the same issue? Also, why can't you run X2GoServer directly on the execution nodes, instead of using ssh -X? If the login node is the only one with a publicly accessible IP, that's not a problem - Activate the proxy feature in the X2GoClient session setup and tell X2GoClient to use your login node as an SSH proxy (i.e. "jump host").

There's a short and simple answer: You cannot. The longer version, resulting in the same outcome, is this: You can hide the built-in functionality on X2Go, both server- and client side, but remember that X2Go is using SSH underneath. And once a user has SSH access with sufficient privileges to run X2Go, they can also exchange files. Yes, even if you block sftp/scp AND portforwarding. X2Go is NOT a security mechanism. So please do not attempt to use it as such - you will fail, as smarter minds than you have failed before you even thought about it. It. Cannot. Be. Done. If you're thinking about abusing X2Go as a security mechanism, you should take at least three steps back and look at your problem from a distance. Most likely, there will be a better solution somewhere else, by taking a different approach. Example: The last time we had someone asking for this was when they had a LibreOffice spreadsheet that was supposed to do some calculations using some hidden formulas; they wanted the user to be able to see the result of the calculations, but not the formula (and obviously, they shouldn't be able to copy the Calc sheet, either). For that use case, it is actually way simpler to use LibreOffice's built-in command line processing of files and a web service - query the input data via web form, paste them into the LibreOffice Calc sheet on the command line, and have LibreOffice open that file in headless mode to convert it to a PDF. That's clean, completely hides the formulas and the Calc sheet from the user, and doesn't require applying kludge over kludge just to be outsmarted by a kid that copies a QR-Code based File Encoder Macro into a LibreOffice Document or bash script. > Note: I confirmed my mailing subscription, would be great if you can accept > my question.

[X2Go-User] X2Go: The Gathering 2020 AKA V/RUS (2020-09-18 - 2020-09-20) will take place at Stuttgart's hackerspace "shackspace"
Dear $ALL, As stated in the subject line, X2Go: The Gathering 2020 - AKA V/RUS, the Virtual/Remote User Symposium - will take place at Stuttgart's hackerspace "shackspace", from Friday afternoon, 2020-09-18, to Sunday afternoon/evening, 2020-09-20. X2Go: The Gathering is the annual event where users, admins, and developers (including the i18n volunteers) of X2Go meet face to face, to discuss current X2Go-related issues, fix open bugs, and have a good time getting to know each other. As there is some overlap between X2Go, Arctica, and orca e.V., you can expect to meet members of those groups as well. Due to the Covid-19 pandemic, this year's X2Go: The Gathering will be a hybrid event with minimal on-site participation. We will be live-streaming the event, probably via Jitsi or BigBlueButton, and most likely we will have a YouTube stream going on as well. Links to the streams will be posted on <http://wiki.x2go.org/doku.php/events:x2go-gathering-2020> each day before the stream begins. *ATTENTION!* If you're interested in joining us *physically*, please contact <mailto:x2go-m...@baur-itcs.de> with the text "The Gathering" somewhere in the subject and bug me publicly on the X2Go-Project list if you don't receive a confirmation by e-mail after a day or two. We will not be providing accomodation this year (so if you cannot commute daily, you will have to look for a hotel/hostel room yourself), *but we still need your contact info* if you wish to take part in person, due to current Covid-19 health regulations. Also, you will be required to wear a non-medical everyday mask or comparable mouth and nose cover (of course, better masks like N95/KN95/FFP2/FFP3 are okay as well, as long as they do not have an exhalation valve), both when using public transport (and while waiting at the platforms/stops), as well as inside shackspace (you will likely be allowed to take the mask off while sitting at your desk, but we cannot guarantee that yet). For joining us *virtually*, you can join in any time, even on short notice, no sign-up required (it would still be nice if you'd let us know in advance, so we can make sure we have sufficient server and streaming capacity). We will be updating the Wiki page <http://wiki.x2go.org/doku.php/events:x2go-gathering-2020> as more information becomes available. As this year's event is a hybrid event with minimal on-site participation, 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> CFD.direct, one of our long-time sponsors (<https://wiki.x2go.org/doku.php/doc:sponsors>), has already done so - and not only that, they have increased their funding from 700 EUR, as originally planned, to 1000 EUR, as you can read here: <https://wiki.x2go.org/doku.php/events:x2go-gathering-2020#sponsoring>. We will be pooling their sponsorship money with another donation by KLO Ingeniería Informática, so we will have 1100 EUR at our disposal. This money will be used to try to tackle the long-standing clipboard issues in the NX-libraries. If you want to add money into that pool, or want to sponsor other X2Go-related work, again, please see the above list of companies/individuals available for such work.

Hmm, could this be a disk full / read-only mount issue, or maybe a hung/stuck NFS mount somewhere? Or an issue with "private tmp"? The sessions database is at /var/lib/x2go/x2go_sessions if you're using SQLite (the default).

If so, you might want to check out X2Go-TCE-MMD (MateMiniDesktop). This is more of a hybrid, than a thin client. It has a local desktop and browser, thus allowing you to run videoconferencing sessions locally. For your remote applications, you would then use "Published Applications" instead of one of the regular Desktop Environments.

[debug log] > Hope somebody can make some sense of this. I can assure you that X2GoClient works just fine on a Raspberry Pi model *3*. So either it's something particular to the model 4 or it's an issue with the Ubuntu server side. Just a wild guess: The Pi 4 has an option to use a KMS driver, and in raspi-config, there's an option to turn this new mode on and off. I would try turning it off to see if maybe it's a display issue (X2GoClient being unable to open the display). See <https://www.raspberrypi.org/documentation/configuration/raspi-config.md> - I'd try setting it to "Legacy". Probably requires a reboot.

Looks like you have several issues. 1) Regarding the sticky keys: What happens when you use a different desktop environment instead of XFCE, say, LXDE or MATE? If you don't have them installed and are unable to install them, you could also use "Published Applications" instead of a Desktop Environment for a test. Also, even though you say it happens using all editors, could you name one specifically that we can use to reproduce the issue? 2) Regarding the latest version of X2GoClient not working for you: Please try to install it again, and check the "debug" checkbox during installation. This will install x2goclient.debug.exe alongside x2goclient.exe. After that, open a cmd.exe on your machine, cd to the installation directory, and run: x2goclient.debug.exe --debug 2>&1 >%TEMP%\x2godebug.log Then try to establish a connection. Close X2GoClient when the connection fails. After that, open the file %TEMP%\x2godebug.log with an editor and paste its contents here.

Not that I would be aware of. It might work if you're using the temporary SSH key feature of the broker that's used for autologin after successfully authenticating against the broker. Do not allow password logins via SSH on your X2GoServer, enforce the use of keyfiles instead - and tell SSHD to look for them *only* in a directory that the users don't have write access to (so they can't place their own, permanent key there). Of course, the broker will need to know it needs to dump the temporary keys there, rather than in ~/.ssh/ ... But, once they're logged in, they can spawn their own instance of ssh on a "high" port, and when they run this in a screen or tmux session, this instance will remain running, even after they terminate their original X2Go connection. So you would need a firewall rule somewhere along the way that only allows inbound connections on port 22 (or whatever you're using for SSH).

"auto login" is required if you're using *either* an SSH-Agent like Pageant, *or* you do not want to specify a keyfile, and instead expect X2GoClient to search for such a file matching one of the standard file names for key files in the default locations. > Question: Does the term 'default SSH key' reference the id_rsa key created > by the ssh-keygen.exe or something else? It references a keyfile that matches one of the standard name patterns and is located in one of the default locations for keyfiles. It does not matter which tool was used to generate the key, as long as the format is the usual OpenSSH keyfile format - i.e. NOT PuTTYgen. > Question: Does passwordless login require the use of Pageant or other > tools, or can it be accomplished solely with x2go settings? No, Pageant is not required as long as you use a keyfile that is in OpenSSH format and you either named it appropriately and placed it in one of the default locations, or you specified the proper path and file name to it in the GUI.

Like I said, X2GoClient can only use OpenSSH keys - not PEM, and neither PPK. To use a PPK file, you need to load it into pageant first, and pageant will take over authentication, so you don't specify the key as a x2goclient --something parameter. Instead, you use --broker-autologin.

X2Go is not a security mechanism, X2Go is a remote desktop/remote application tool. You need to use the standard Linux security mechanisms to lock down your system. However, I would guess it's near impossible to lock it down in a way that login via SSH to a shell is blocked, but X2Go still works. If you want to increase security against people that are not supposed to be using your server, that can be done with 2FA (either SSH keyfiles, or various OTP methods). But blocking a legitimate user from running the shell, while still allowing X2Go ... no.

No. Your URL is wrong. When using ssh, you need to specify the file system path to the broker executable as part of the URL, and separated from the server name/IP using a colon: --broker-url=ssh://your-server-here:/usr/bin/x2gobroker-ssh Also, 1192.something is not a valid IP, you might want to double-check that.

So it seems you have some kind of mechanism in place that checks for active users/connections, and suspends the server if there are none. Maybe a cron job that checks the output of "w" or "who"?

As a reminder, we have a similar thing in NX-X2Go, the "magic pixel" -
which is annoying in fullscreen thinclient sessions as well. That's why
code has been added to the server to disable it ("-nomagicpixel" in

Maybe you could make your code disable the menu bar if the same config

Am 08.05.20 um 17:04 schrieb James M. Pulver: > Trying again to send to list. I kind of wish default reply was reply to list, > I end up sending just to one user... This list is following the rules set out in RFC 2369, so it sets a List-ID header, which, in sane mail clients, causes a "Reply to List" option to become available when replying. This RFC is from 1998, so it's not like it has just been introduced yesterday and mail client software coders didn't have enough time to support this feature. Mangling the Reply-To header (which may have been set intentionally by the original sender) with list software is bad form. E.g. if you want to post to the list, but want to set the Reply-To to another list or to your E-Mail address, so replies don't hit the list, this would be overwritten, pointing at the list again. This is confusing both for a sender that doesn't expect it, and for recipients that expect their reply to reach your inbox instead of the list when intentionally selecting "reply" instead of "reply to list". We're using manually set Reply-To headers as a replacement for "Follow-Up-To" (a header only available on newsgroups), when crossposting announcements across multiple X2Go lists, but wish to channel the ensuing discussion to only one of the lists. So having the list server set to override this would be bad. And I think I also used it with a Reply-To set to my personal inbox for the X2Go: The Gathering registration E-Mails. At least it makes sense for these - people probably don't want to post their personal details to the list when they want to sign up for the event. TL;DR: Please complain to the manufacturer of your E-Mail client, or switch to a different E-Mail client, if it can't handle list replies the way it should. -Stefan -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

Residential DSL: Downstream: 5.435 MBit/s max, 5.233 MBit/s average Upstream: 0.465 MBit/s max, 0.427 MBit/s average Ping latency: 23.00 ms min, 28.94 ms average Residential Cable: Downstream: 35.14 MBit/s max, 28.06 MBit/s average Upstream: 2625 MBit/s max, 2.426 MBit/s average Ping latency: 32.00 ms min, 39,38 ms average (iow, higher throughput than DSL, but higher latency) -> This will, however, get worse, as Cable is a shared medium and people in the area are getting fed up with their DSL speeds and are switching over to Cable as their contracts expire. LTE, 1st of 2 providers: 3 out of 5 bars Downstream: 4.715 MBit/s max, 2.029 MBit/s average Upstream: 3.923 MBit/s max, 3.706 MBit/s average Ping latency: 48.00 ms min, 60.50 ms average LTE, 2nd of 2 providers: 2 out of 5 bars Downstream: 0.325 MBit/s max, 0.214 MBit/s average Upstream: 0.325 MBit/s max, 0.225 MBit/s average Ping latency: 64.00 ms min, 79.25 ms average Now step outside and move another 800 meters towards the city limits, and LTE provider 1 drops to UMTS/EDGE (and GSM on a bad day), while LTE provider 2 actually goes up to 3-4 bars and gets 3-7 MBit/s peak rates - but they are short peaks/bursts in an otherwise very mediocre reception. Nothing you want to rely on. Again, this isn't Mooville, West Virgina, with 100 inhabitants and 75 of them cattle, but a larger city in the self-proclaimed high-tech nation Germany. Even Finnish rural areas have better UMTS and LTE coverage than we in Germany have, at the outskirts of our cities. And no, I'm not making this up, I've been to such areas in Finland in the last two years, and I know what the reception there was like. So NX will be here for quite some time, there is a need for it, and for less fancy, but lightweight desktops that work well with it. -Stefan -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

That guess goes into the right direction, I'd say. Just a few days ago I ran OpenBox on :1 inside Xephyr, and made the mistake of clicking "exit" there. Zap, my actual session on :0 went down as well. -Stefan -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

For some reason, KDrive sessions are detected as local sessions. So users are allowed to click "shut down the server" - and it will actually happen. On the other hand, they are getting popups about Network connections that ask for sudo permissions to continue and whatnot. A plain, classic-NX X2Go session on the same server works just fine. $SOMETHING inside the DE is trying to tell local and remote sessions apart (which is a good thing), and KDrive is confusing this detection mechanism due to how it works, so you get all those weird effects (which is a bad thing). -Stefan -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

I'll check which one is faster. The thing is: 1) It would satisfy the sponsor's requirement for NX support 2) It uses the same Server-Client protocol as Alex' solution 3) It is available now, without having to wait for the DEs to adapt The NX->novnc approach may cover conditon 1), but not condition 2), so, extra effort is needed to make it work. Using KDrive only breaks condition 1) and 3). Fantasizing a bit here: When using "NX compatibility mode" in KDrive-HTML5, it would merely have to start a session that only consists of X2GoClient in hidden mode (or pyhoca-cli) with a session to localhost, passing through the credentials provided via the HTML5 client. Maybe add OpenBox or some other minimalistic window manager, but no full DE. So no annoying popups from a DE that believes it's handling a local session. This is not about speed. This may not even be a long-term solution - once KDrive works with all major distros/DEs, it may even be something we can drop again. But for now, it would cover all three conditions listed above, in a timeframe that doesn't sound like it would have to be that far in the future as full major distro/DE support. -Stefan -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user

Again: Because classic X2Go HTML5 support is what the sponsor wants to see. KDrive, Broker, Sound, Printer- and Filesharing - nice bells and whistles, but not what the sponsor wants. NX is stable, NX is what they're used to, so they ask for it to be used. We're way past the stage where we could negotiate "Can't we just use KDrive instead of NX?". I would also like to remind you that I don't consider KDrive production-ready for general use yet. It may work for Alex' customers, but last time I tried, I still saw quite a few quirks due to the session not recognizing that it is a remote session (showing popups that only make sense for a local user, granting permissions that a remote user should not have, etc.). Those are blockers for a stable release and from my understanding, they need to be fixed in the Desktop Environments, not on the X2Go/KDrive side. And such changes are unlikely to get introduced/back-ported to already-existing long term releases of Linux distributions - which most sponsors/commercial users of X2Go are using. So I doubt we'll see KDrive support becoming generally available until the next major releases of the most popular long-term distros. And that's not how long a sponsor should have to wait for a sponsored feature. Plus it might have a negative impact on their willingness to fund further work. In a Pre-Corona world, I would have said I'd like to see results before or at the next Gathering. But if we get hit with another infection wave, who knows when the next Gathering will be, so that's not really an "anchor" for a time frame I would like to use right now. ;-) > The NX -> x11vnc -> NoVNC solution will always be worse (slower, more > itchy and glitchy). Maybe you could grab the NX output while still on the host (like, running a fake X2GoClient directly on the server), then push the output towards the HTML5 client the same way Alex' KDrive-HTML5 solution does? That could work as some kind of compatibility layer. That way, the DE would recognize a remote session (even though it's actually connected through 127.0.0.1 or ::1), so we don't have to deal with the quirks/wait for the fixes, yet you'd still only need one backend to talk to the HTML5 client, not two. -Stefan -- 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 ___ x2go-user mailing list x2go-user@lists.x2go.org https://lists.x2go.org/listinfo/x2go-user
