X2GO Client On Windows Starts and Terminates In A Few Seconds
by Alexandra Lu (Nokia) 15 Sep '23

15 Sep '23

Hi, I'm running X2GO client V4.1.2 on Windows 10, and trying to connect to a Linux PC running Ubuntu 22.04. I use MATE for the Session Type, and when trying to connect, I could see that the Linux desktop window starts then terminates in a few seconds, and the following x2go error log is created on the Linux PC. I'm guessing the last assert was the cause of the crash. Does anyone have any suggestions on how to fix it? alexanlu@kanalexanlu:~$ cat .xsession-x2go-kanalexanlu.labs.ca.alcatel-lucent.com-errors XSession-x2go: X session started for alexanlu at Thu Sep 14

Next Events/Upcoming X2Go and orca e.V. Sponsorship Drive - Tomorrow, 2023-09-05
by Stefan Baur 04 Sep '23

04 Sep '23

Dear $ALL, X2Go will be present at LinuxDay.AT <https://www.linuxday.at/> in Dornbirn, Austria on Saturday, September 30th, and also at the IT-Kongress <https://it-kongress.com/> in Neu-Ulm, Germany, on Thursday, November 9th, 2023. At both events, 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. At LinuxDay.AT, there will also be a talk with a live demo of how you can run a small X2GoServer instance in the Google Cloud, for free, using Tor (The Onion Router) to log in. The talk at IT-Kongress will be a behind-the-scenes look regarding the customer-driven development that led to the creation of X2Go-KDrive. (Note that both talks will be in German, but our booth staff at both events is fluent in German as well as in English.) If you're planning to attend and/or are in the area, feel free to stop by and say hi! Both events are free, though IT-Kongress requires registration. 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*. You can find our donation pages here: X2Go (English): <https://www.betterplace.org/en/projects/111056?wirwunder=235> X2Go (German): <https://www.betterplace.org/de/projects/111056?wirwunder=235> orca e.V. (English): <https://www.betterplace.org/en/projects/111057?wirwunder=235> orca e.V. (German): <https://www.betterplace.org/de/projects/111057?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 are usually tax deductible for German tax subjects. Note that there is a special sponsorship drive sponsored by our funding platform, betterplace.org: Non-recurring donations up to 100 Euro made on Tuesday, 2023-09-05 (starting 00:00 CEST) will receive 20% on top directly from betterplace.org. Larger donations will receive 20 Euro on top instead. This offer is only valid until a funding pool of 12.000 Euro is depleted. So the earlier you donate on this particular day, the higher the chance that your donation will receive the bonus from betterplace. Kind Regards, Stefan Baur (with his X2Go Event Planner hat on) *If times are rough for you and you can't afford to donate, don't feel bad! You can also help us by forwarding this announcement to whomever you seem fit - e.g. your local Linux user group, your social media followers, etc. If you're on Twitter, you can retweet and like the following to help: <https://twitter.com/farbenstau/status/1698651187577282841> (English) <https://twitter.com/farbenstau/status/1698651871773086181> (German) Feel free to copy the text and links of these Tweets to any social media platform that you are using. -- 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

Wrong Shell When Connecting with X2Go
by Joe W 24 Aug '23

24 Aug '23

I have another system that I installed Rocky Linux 8.8 onto. I created some logins and set the shell to be /usr/bin/tcsh. I installed XFCE. When I log in at the computer and open a terminal then the tcsh shell is being used as expected. When I connect using X2Go then open a terminal the shell is bash. Any idea why this is happening? Thanks, Joe

system upgrade
by o1bigtenor 22 Aug '23

22 Aug '23

Greetings Just did a system upgrade (debian bookworm) and I have an updated system except for x2go. The following is what I am getting. (Have tried changing bullseye to bookworm and the result is the same.) >http://packages.x2go.org/debian/dists/bullseye/InRelease: Key is stored in legacy trusted.gpg >keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details. Have looked for a specific technique to update the key storage. Can't find such. Checked with the x2go website to see if there is any somewhat current information - - - except the website is current for - - well, some time ago. Please - - - any suggestions for how to remove this 'issue'? TIA

colord fix needs update for Debian >= 12 / polkit >= 120
by Philipp Huebner 15 Aug '23

15 Aug '23

Hi all, on Debian 12 I was getting that annoying color-manager polkit authentication window again. Turns out, the file /etc/polkit-1/localauthority/10-vendor.d/x2goserver-no-colord.pkla installed by x2goserver no longer has any effect because that backend is obsolete in polkit >= 120 or so. I ported the original rule to /etc/polkit-1/rules.d/color-manager.rules with the following content: polkit.addRule(function(action, subject) { if (action.id.match("org.freedesktop.color-manager") && subject.local == false ) { polkit.log("action=" + action); polkit.log("subject=" + subject); polkit.log("action '" + action.id + "' denied!"); return polkit.Result.NO; } }); That solved the issue for me. Supposedly one can also install the package polkitd-pkla to get back support for the old file, but I have not tried that approach. Best wishes -- .''`.

x2gokdrive doesn't like connection interruption
by Neal Becker 03 Aug '23

03 Aug '23

client and server both fedora f38. x2gokdriveclient-0.0.0.1-1.fc38.x86_64 I find that when connection gets interrupted 3 bad things can happen: 1. client uses 100% cpu 2. Trying to reconnect, screen starts to open and immediately closes. Then on next attempt a new session starts, old session is lost. 3. With client connected, closing laptop lid should initiate sleep. Instead client runs 100% cpu and machine doesn't sleep.

Can't use ssh-agent / ECDSA key file for passwordless login [MacOS client]
by Aaron 28 Jul '23

28 Jul '23

Hi all, I'm having trouble getting the x2go client to authenticate with passwordless login options other than kerberos. Specifically, I've tried auto login (via SSH agent) and supplying the path to my OpenSSH private key (which is an ECDSA key). Kerberos works for me as long (as I have a valid ticket), but I want to connect using the the ECDSA key, for reasons I'll explain below. I suspect that the ECDSA format key is not supported by my current client version, but if someone could confirm (or deny) that, I would appreciate it; and if it's possible that it might work with a more up to date client build / build against an updated LibSSH or something, that would be good to know too. I don't currently have the wherewithal to build my own copy of the client for MacOS, but that might provide some incentive for me to try sometime soon. Some background: I'm using x2go at work to connect from my Macbook Pro to a Linux server. To connect using Kerberos, I need a valid ticket, and to get a valid ticket, I need to first connect to the corporate VPN. However, I don't need to connect to the VPN in order to use SSH (from a terminal), thanks to a proxy software (a ProxyCommand in my ~/.ssh/config). If I already have a valid Kerberos ticket, the X2go client will connect using Kerberos, without VPN (that is, the ProxyCommand seems to work). However, I don't want to have to connect to the VPN just to renew my kerberos ticket when ssh itself will work using the ECDSA key I obtain. (It will also work using my password, but that is a temporary measure... my employer is phasing out password-based ssh in favor of requiring U2F). To be clear, the proxy command doesn't seem to be the issue; I encounter the same problem when I'm connected to the VPN. I've attached two files (with usernames and hostnames substituted), one the output of ssh -vvv (succes) and the other the output from /Applications/x2goclient.app/Contents/MacOS/x2goclient --debug (failed). Both were run while connected to the VPN. The x2go session was set up with "Try auto login" checked, Kerberos 5 unchecked, and "Use RSA/DSA key" left blank (the log also shows that the contents of my ssh agent were valid in the terminal). Trying after supplying a path to my ~/.ssh/id_ecdsa file under "Use RSA/DSA key" has the same result.
