Next Event/Upcoming X2Go and orca e.V. Sponsorship Drive - Starting Tomorrow, 2024-03-26, to 2024-03-28
by Stefan Baur 25 Mar '24

25 Mar '24

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. 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/1772238185239634302> (English) <https://twitter.com/farbenstau/status/1772239658727968852> (German) If you're on BlueSky, you can reskeet and like the following to help: <https://bsky.app/profile/farbenstau.bsky.social/post/3kojhnqvcn423> (English) <https://bsky.app/profile/farbenstau.bsky.social/post/3kojhzohqz423> (German) And on Mastodon, you can like and boost the following to help: <https://infosec.exchange/@farbenstau/112156390300051818> (English) <https://infosec.exchange/@farbenstau/112156394812114108> (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

Missing fonts

Hi, I'm trying to use software called MB-System over X2Go but I seem to be missing fonts. Is there a way I can add these? -misc-fixed-bold-r-normal-13-120-75-75-c-70-iso8859-1 -misc-fixed-bold-r-normal-13-125-75-75-c-70-iso8859-1 MBSystem dependencies need XFonts-100 and I made sure to install every font option when installing X2Go.

x2go client on fedora 40 rc2

x2goclient on windows
by Witter, Geert 31 Jan '24

31 Jan '24

Hello, 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? Kind regards, Geert Witter Senior Software Engineer Mobile: (NL) +31 6 53 89 61 02

error
by richard lucassen 28 Jan '24

28 Jan '24

On one of my laptops I am not able to set up a connection to the x2go server. When starting a custom desktop: ssh-agent startx wmaker I get the black "x2go" screen and then crash. I see this in the logs: daemon.warn: Jan 26 11:41:54 /usr/libexec/WindowMaker/wmaker[483025]: (catchXError(startup.c:118)): warning: internal X error: RenderBadPicture (invalid Picture parameter) Request code: 139 Request minor code: 7 Resource ID: 0x4009d9 Error serial: 28162 I have more clients with the same version 4.1.2.2-2+b1 (Debian Testing) that connect to the same server and do not suffer from this issue. It is not an x2go problem AFAIK, but can anyone give me a hint where to start looking for a solution? Richard. -- richard lucassen http://contact.xaq.nl/

Network of Debian 12 workstations, seem to have SSH issues more than X2Go issues
by Nasi Chassoulas 23 Jan '24

23 Jan '24

Hi all, My first post here. I have spent a few weeks trying to set up X2Go to manage a small network of Debian based workstations. Some of them are user workstations, some headless servers, some using Gnome (X11 as far as possible, not Wayland). I have had some success accessing user desktops sessions, but I have broken this with some sshd_config changes. I would appreciate any advice. I have checked some logs, with this being the most obvious issue. XSession-x2go: X session started for administrator at Tue 16 Jan 2024 20:51:43 SAST dbus-update-activation-environment: setting DBUS_SESSION_BUS_ADDRESS=unix:path=/tmp/dbus-kVdJKgUoT3,guid=bc3f454dec8a0f9639cff89f65a6d03f dbus-update-activation-environment: setting DISPLAY=:51 dbus-update-activation-environment: setting XAUTHORITY=/home/administrator/.Xauthority dbus-update-activation-environment: warning: error sending to systemd: org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.freedesktop.systemd1 exited with status 1 xrdb: Connection reset by peer xrdb: Can't open display ':51' xhost: unable to open display ":51" In the X2Go client, on some clients I get the 'session select' window, on others I get stuck in a password prompt loop. If its not a basic issue with X, I suspect its with SSH. I appreciate any help offered. Thanks for the development of a great product. Thanks, Nasi

only a black screen in the X2Go Session
by Poupart Erwann 10 Jan '24

10 Jan '24

Hi all, I'm a new user of X2Go. I have installed the X2Go server on a centos7 VM and a X2Go client on my PC (Windows). When I start a X2Go Session trying with Gnome (GDM active on my server) or even with XFCE, I only have a black screen that appears with no window manager or anything else to interact. Is there some specific configuration to do on the server side ? Thanks by advance for any help. Regards, Erwann.
