Session resume broken when keyboard explicitly configured
by Hanno Foest 10 Sep '22

Hello, after updating my Devuan chimaera (Debian 11.1) remote system to x2goserver etc. 4.1.0.4-0x2go1.2~git20220808.1949+11.heuler.1, session resume stopped working, nothing happened and I was getting a timeout eventually. Logged error: Info: Waiting for connection from 'localhost' on socket 'tcp:*:61090'. Info: Aborting the procedure due to signal '1'. Session: Display failure detected at 'Thu Sep 8 02:30:16 2022'. Session: Suspending session at 'Thu Sep 8 02:30:16 2022'. Session: Session suspended at 'Thu Sep 8 02:30:16 2022'. My previous (working) version was from May, so I wanted to revert, but unfortunately the packet repo http://packages.x2go.org/debian/pool/heuler/x/x2goserver/ had only versions from August 8. It would be really good if there were older versions available for such a case... I found out that things started to work again if I set keyboard configuration to automatic, before it was set to pc105, layout de. This needs to be addressed, I guess. After setting the keyboard to automatic, the backspace key stopped working, among other keymap issues (only appearing after resume). This can be fixed with - keyboard_type='null\/null' + keyboard_type='null/null' in /usr/bin/x2goresume-session Hanno

x2go immediately disconnects after connection
by Tristan Miller 08 Sep '22

Dear all, I've been using X2Go on a pair of openSUSE Tumbleweed systems. I just upgraded both and now I'm no longer able to run a remote application or desktop -- the client successfully connects to the server but then immediately disconnects. Below is output from x2goclient --debug showing me trying to launch a remote xterm. Can anyone suggest what the problem might be or how to troubleshoot further? Regards, Tristan [psy:~] $ x2goclient --debug x2go-INFO-1> "Starting X2Go Client 4.1.2.3..." x2go-WARNING-1> English language requested, not loading translator. x2go-WARNING-1> English language requested, not loading translator. x2go-DEBUG-../src/onmainwindow.cpp:1300> Removing apps from tray x2go-DEBUG-../src/onmainwindow.cpp:1268> Plugging apps in tray. x2go-INFO-3> "Started X2Go Client." x2go-DEBUG-../src/onmainwindow.cpp:626> "$HOME=/home/psy" x2go-DEBUG-../src/onmainwindow.cpp:2349> Reading 2 sessions from config file. x2go-DEBUG-../src/onmainwindow.cpp:13380> libssh not initialized yet.

Can't use microphone in x2goclient on MacOS
by Julián Metelski 30 Aug '22

30 Aug '22

Hello. I hope I'm in the right place (otherwise please tell me where to go, thanks!) I have a Linux x2go server with several x2go clients connecting to it, all but one run on windows (where I already know my way around and have successfully troubleshooted several issues), and one running on MacOS Monterrey 12.5.- The problem I have with this client is I can't get microphone sound to reach the x2goserver. I can receive audio in the mac, and in Linux (pavucontrol) I see the microphone being listed, it's enabled and selected and it's not muted, but when I speak I get no sound. In the Mac's sound configuration I see the vumeter move when I speak, and I can record audio in other MacOS applications (for example if I go to www.onlinemictest.com on Safari, the mic works). I didn't find any program or tool to select which stream each application records (like pavucontrol on Linux). Any help is appreciated. Thanks!! Julian

gnome keyring unlock with login
by Brent S. Elmer Ph.D. 26 Aug '22

26 Aug '22

My debian system is set up to unlock the gnome keyring when I log into gnome. When I remote into the machine using x2go I have to use xfce since gnome hasn't worked with x2go for a long time. I have tried many things in xfce to try to have the gnome keyring unlocked at login. It seems like the problem is that x2go does not log in the same way as would be logged in if logging directly. X2go does not appear to trigger any of the pam settings to unlock the gnome keyring. Is there any way to have x2go automatically unlock the keyring when making a connection? I would assume that if the keyring was unlocked when creating the connection that it would remain unlocked on a pause and reconnect. Brent

Greetings, I am trying to use a cloud VM as my host. The host and guest are Linux. Host: Ubuntu 22.04 server with mate-desktop and x3goserver installed Guest: Fedora 35 When the guest connects, I get a desktop. In the upper left corner, I get a Menu. When I click on the menu, a sub-menu gets displayed. However, it disappears before I can select anything. How can I make the menu work correctly, i.e., stay up until I select something? Thank you.

X2Go based on Qt? #

Dear X2Go Support, I'm writing to you because I was expecting that the latest release of X2Go based on *Qt5* as I can see it on the web page... [image: ScreenShot_12138.gif] If I check the Help/About Qt information, I can see that the Qt version is *4.8.6*... [image: ScreenShot_12137.gif] I have installed the latest version of X2Go, which is v4.1.2.3 I believe. Could you please let me know if there is a version available based on Qt5? Many thanks in advance, Mike

X3go win client quits
by David 28 Jun '22

28 Jun '22

Folks I use the X2go client on Windows 10 to access several Linux hosts (mostly Ubuntu). Most work just fine, except one. On this node (let's call it SC), the moment X2go Windows client starts the connect, it terminates. I have selected 'display details', but the client disappears before anything shows up. Since this sequence works talking to Ubuntu 20.04, 22.04, and Centos 7, I'm thinking it has to do with the server... The SC server is running Debian 7 wheezy. I know this is seriously out of date, but updating to a newer release at this time is not possible. The x2go daemon is version 4.0.1.16-0x2go1+git20140926.935+wheezy.main I can successfully connect to the server via SSH (using password), so I know that "ssh works". Any pointers you could provide to help me debug the issue would be appreciated. David

Performance on external monitor
by Jonah Benton 25 May '22

25 May '22

Hi folks, Super happy x2go user on a Thinkpad P1 Gen2 with a 4k screen running Fedora with XFCE. I segregate clients and personal work into distinct users and run 5 or 6 x2go sessions at the same time, switching between them with desktop workspace hotkeys monitored by the master session. Performance is great, even video within an x2go session is terrific. Today the Thinkpad's screen decided to start to fail, so I connected the laptop over HDMI to a 4k external monitor. Now, unfortunately, x2go performance is really suffering- window repaints within a session even with only 1 session are so slow as to be essentially unusable. Window repaints and other rendering activity on the master X session seem about the same. All sessions are 3840x2160, using "LAN", "16m-jpeg", image quality 9. I played a little with those settings but nothing made a material difference. I don't know anything about the X display architecture or the hardware path. Any thoughts from anyone who does on any options to improve x2go performance on an external monitor? Thanks, cheers, Jonah

Hi, with latest version of Ubuntu I'm getting an error when trying to connect with windows x2go client to Ubuntu 22.04 machine (I think it's not so relevant that it's ubuntu 22.04 but newer openssh version 8.9): "kex error: no match for method kex algos:server [Diffie-hellman-group-exchange-sha256], client [curve255519-sha256(a)libssh.org,ecdh-sha2-nistp256,Diffie-hellman-group14-sha 1,Diffie-hellman-group1-sha1]" I have tried to adapt sshd_config via: "HostKeyAlgorithms ecdsa-sha2-nistp256-cert-v01@openssh.com,ecdsa-sha2-nistp384-cert-v01@openss h.com,ecdsa-sha2-nistp521-cert-v01@openssh.com,ssh-ed25519-cert-v01@openssh. com,ssh-rsa-cert-v01@openssh.com,ssh-dss-cert-v01@openssh.com,ecdsa-sha2-nis tp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-ed25519,ssh-rsa,ssh-dss" After that I have restarted sshd service but that did not help. I also tried: HostKeyAlgorithms ssh-rsa,ssh-dss PubkeyAcceptedKeyTypes ssh-rsa,ssh-dss The error message is the same. So I assume that the error is not what the message is telling me but I know that with some of the latest openssh versions several other clients run into problems (putty latest versions fixed it, jump desktop - setting PubkeyAcceptedKeyTypes=+ssh-rsa did work) Any ideas?

Was looking at the nightly builds, and noticed that all the .exe files had the same date/time stamp (back to the 2019 builds). Is that expected?

Broker and file sharing
by Brian Sanders 08 May '22

08 May '22

I am looking at the settings in my x2gobroker-sessionprofiles.conf, and it seems to indicate the broker can set some defaults to turn off allowing printers, and filesystems to be shared. useexports=false print=false I have tried turning these on, and I don't believe they are working. Specifically if I connect to the broker, then a server it servs out. Once connected, I can use the x2go Client window's share folder button. In there I can define an export, and then highlight it and press share. This will then show up on the workstation. Am I missing something? What do these options do if not turn on/off the ability for the user to make these shares? If I wanted to disable these shares/printing, and then enable them for specific hosts by overriding it, are there other options I can activate to achieve this?

x2go server on debian: readonly partition
by Vikas Rawal 02 May '22

02 May '22

I am running x2go server on debian testing and connecting to it from another linux machine. Everything works fine but occasionally (approximately after 2-3 days of use over which I connect and disconnect from the client many times), the host machine says the /tmp/... is on a read-only partition, and everything stops working. x2go client does not connect when this happens. I can ssh to the server but nothing works on it. I am unable to even cleanly reboot the machine when that happens. I only need to physically hard-boot the machine. I don't know if this is happening because of x2go, but it never happened before I started dabbling with x2go. Is this a known problem? Any ideas about how to debug? V.

Suspend on disconnect
by Vikas Rawal 30 Apr '22

30 Apr '22

Does x2go cleanly suspend if the client loses connection or the laptop running the client is just suspended by turning the screen shut? Do the user systemd services keep running when x2go session is suspended? Something like what would happen when a tmux/screen session is detached. V.

Unlock screen in KDE
by Klaus Vink Slott 24 Apr '22

24 Apr '22

Not really a X2go problem, but we use X2go at the IT University of Copenhagen. I prefer to use it with KDE, and apart from the slow startup it works really well against our Centos 8 servers. As I mostly like to run full screen to ensure that Alt+Tab and other shortcut operates as expected. But this gives one problem: When I leave my workstation I am used to lock my keyboard by pressing Ctl+Alt+l but this in full screen this locks the remote desktop - and I find no way to unlocking it again. As a workaround I changed the lock keycombination on the remote, but I would like some proper way to unlock the remote. Any suggestions? -- Regards Klaus

Are there any updated instructions for this: https://wiki.x2go.org/doku.php/wiki:development:glx-xlib-workaround ? I am unable to build the mesa driver on debian testing. The recent versions do not allow the option "glx=gallium-xlib" while the older versions do not build. Has anyone tried this recently? Unfortunately several of the applications I use are not working because of this. V.

Unlock or disable KDE Screen saver
by Klaus Vink Slott 01 Apr '22

Hello Anyone found a way to disable the KDE screen saver or know how to unlock the damm thing? I have disabled the timer based lock. But when I leave my desk at work, I have always been used to hit Ctrl, Alt, L and the screen locks. This is very difficult to unlearn and when I do lock it, I have found absolutely no way to unlock the screen without killing the remote desktop. -- Regards Klaus

Sessions can't be suspended, disconnected sessions can't be resumed.
by Hakan Bayındır 19 Mar '22

19 Mar '22

Hello all, I'm having a strange problem with a long-running X2Go installation. Users cannot resume their "disconnected" sessions. The client/server starts a new, clean one for them. I've debugged the issue but I was unable to paint a coherent picture. Here what I've found: - Disconnected sessions are still active and they're in suspended state. / tmp/.x2go-$USER/$SESSIONPATH/state files show "SUSPENDED" for the same sessions which are running at the background. - However "TERMINATED" sessions are not cleaned. They've piled up. - "x2golistsessions_root" returns empty, even if there are active, running sessions. Running "x2golistsessions" under a session via user also returns empty. - The SQLite3 database in /var/lib/x2go is empty except "used_ports" table. Even in that table there are stale entries, but the list is not very long. - x2gocleansessions logs only show usual session startup woes. - unresumable sessions show that the connection has disconnected unexpectedly, hence X2Go did normal resuming operations. - Suspending a session via client fails. Clicking close button does nothing, right clicking to tray icon and selecting suspend shows an error dialogue: "Failed to suspend with session ID $USERNAME-$DISPLAY-$ID-$DE-$COLORDEPTH" (It's properly populated, so the ID is there). The thing is getting more complicated since none of the commands have help, verbose outputs and cannot debug anything very deeply. I've deployed this thing to much larger systems before, and it was also working flawlessly here, and I'm at loss currently. Lastly, the OS is CentOS 7, and it's updates to top patch level, including the latest X2Go server release done a today or a couple of days ago. Any help is greatly appreciated, Cheers, Hakan

font path not set correctly
by Hanno Foest 19 Feb '22

19 Feb '22

Hi, after setting up a new remote x2go instance (using Devuan) I noticed that xterm complained xterm: cannot load font "-misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso10646-1" I traced the issue to the font path (displayed with xset q) missing /usr/share/fonts/X11/misc, so I added it with xset +fp /usr/share/fonts/X11/misc and things started behaving normally again. - But: Where is the font path in x2go actually being set? I'm not sure if some autoconfiguration failed, or if it's a compile time issue, or something else. - For the same issue there's a bug report in Ubuntu, see https://bugs.launchpad.net/ubuntu/+source/x2goserver/+bug/1891825 and especially the remark about the man page at the end.

Display Going Black When Clicking on Certain Windows on remote system
by Joe W 30 Jan '22

30 Jan '22

I use X2Go to connect from my local Linux system to some remote Centos 7 systems where I run Cadence Virtuoso software. As far as I know the systems and X2Go are set up the same. Systems have the latest OS patches. X2go was installed from Epel repo. client is v. 4.1.1.1-1.el7 server is4.1.0.3-9.el7 There is one system that I connect to where when I start the X2Go session then the screen goes black for a second or two. When I run Virtuoso on that system then whenever I click on the main Virtuoso window or a Virtuoso graphics window then my screen goes black. If I click outside the Virtuoso window then the screen reappears. If I click on the Virtuoso library manager window then the screen stays on. Note that I am running X2Go windowed but my entire screen goes black, not just the X2go window. Any suggestions what could be going wrong and how to debug it? I do not know how to turn on debugging in the Linux version. I am wondering if it is something weird with the color palette since it only happens for certain windows. I can connect to other systems without issue that are set up the same. Thanks

X2Go TCE pxe complications
by MacGregor Family 30 Jan '22

30 Jan '22

Hello, I have been given a couple of Termtek TK-3550 thin clients and I am trying to set them up to open into my Ubuntu 20.04 server at my home over our ethernet LAN. These devices don't have much memory so I have been following the instructions to install the "Classic, NFS- filesystem-based X2Go TCE". I have setup a Virtual Box VM, running Ubuntu 20.04 with a bridged network adapter and a permanent IP address, to be the pxe server. I have followed the instructions as best I was able but I am still having difficulties. I think one problem is likely to be that our cheap router, which provides our DHCP server, does not allow me to nominate the "next- server" or the filename. In an attempt to address this I have installed dnsmasq on the pxe server VM and am running dnsmasq. The dnsmasq.conf is as follows: port=0 log-dhcp dhcp-range=192.168.1.0,proxy dhcp-boot=pxelinux.0 enable-tftp tftp-root=/srv/tftp (I have also tried tftp- root=/opt/x2gothinclient/chroot on this line) The thin client is set to boot over LAN and the dhcp-log on the pxe server looks like this when I turn the thin client on: I'm clearly a complete novice but it seems the thin client is finding its way to the pxe server. Unfortunately the thin client trys to boot until it times out, reporting: "No boot filename received". It then just boots its decades old version of Windows CE. Note that when I changed the tftp-root path in dnsmasq from /opt/x2gothinclient/chroot to /srv/tftp it had some effect on the dhcp log (it nominated its terminal id in a second line) but the nett result did not change. I should add that I have exported both /opt/x2gothinclient/chroot and /srv/tftp with the NFS server. I only switched to /srv/tftp because that's where pxelinux.0 is and I assume that is the file it is looking for and failing to find. Basically I have been trying to get this working for a couple of days without success, I have decided to seek expert help. I apologise for my ignorance, I understand that hobbists like myself are probably incredibly annoying. Regards Stuart MacGregor

session freezing

Client and server are both Fedora 35. xfce session. This setup has worked for years. An SSD failed on the server, and after re-installing F35 on it, now x2go session keeps freezing. Seems to happen at least when it is left running unattended. The x2go screen is shown, but unable to get focus into any window, click on any icon. Suspend/unsuspend does not fix it. Only terminate and restart fixes it. Any suggestions? Thanks, Neal -- *Those who don't understand recursion are doomed to repeat it*

Mac Client SSL
by Brian Sanders 24 Jan '22

24 Jan '22

I have been working on getting a Mac client connected to my broker and workstations, and have found that this client specifically seems to be using very old openssl options. I have had to update my servers to get the SSH connections to work, and even had to do some patching to the broker-daemon to force it to use TLSv1 to support these clients. I don't have either of these issues with my Ubuntu client, so I am even running two broker daemons on different ports just so these clients can have weaker options. Is there a newer client, for Mac, or can one be compiled with the exact same client code, just with update libraries for ssl? My edits thus far are as follows to support this version: x2go-server: add +diffie-hellman-group14-sha1 to sshd_config x2go-broker-daemon (whith https certs): Force TLSv1 to be supported, and update ciphers to allow security level 1 (needed for TLS1) + context = ssl.SSLContext(ssl.PROTOCOL_TLSv1) + context.set_ciphers("DEFAULT:@SECLEVEL=1") + context.load_cert_chain(x2gobroker.defaults.X2GOBROKER_SSL_CERTFILE, x2gobroker.defaults.X2GOBROKER_KEYFILE) + http_server = tornado.httpserver.HTTPServer(application, ssl_options=context)

Auto-login assistance
by Brian Sanders 19 Jan '22

19 Jan '22

I am trying to get the broker to work with the auto login feature, and I can't seem to get it to work. I am using an ansible playbook and building a broker, and then 2 workstations. I setup wks1 to autologin and wks2 with out. I can use wks2 just fine, but when I try and use wk1, It seems the new key is added, and the workstation indicates that it accepts a session for my user. However the X2go client then shows me a login/password box rather than logging me into the session. I have logs from the server and the workstation, can someone help point me in the right direction?

xfce not usable (fedora f35)
by Neal Becker 11 Jan '22

11 Jan '22

I just tried xfce as a remote desktop. Client and server both fedora f35. I found it unusable. After desktop starts, I tried clicking icons to open a terminal, and the file manager. Nothing appears. Tried close x2go and reopen. Now the missing terminal and file windows appear. Try to drag the windows and they leave a trail of rectangles. Seems windows are not being repainted. Any suggestions? Thanks, Neal -- *Those who don't understand recursion are doomed to repeat it*

Questions regarding features and configuration advice of X2go
by Jörg Kastning 21 Dec '21

21 Dec '21

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. These users must not be able to transfer any data or files to or from the target host. Question 1: Is there a way to deactivate the clipboard or any drag'n'drop feature in x2go-server to prevent users from transering data? Question 2: The documentation (at URL https://wiki.x2go.org/doku.php/doc:newtox2go#installation_and_use) mentions that the SSH server handels the X2go connections. Are there example configs that restrict SSH access to X2go but prevent users from transferring data via tools like scp or rsync? Thank you in advance for your replys. Regards, Joerg

Failed messages during startup & small session menu
by Olaf 20 Dec '21

20 Dec '21

Hi! The start process from the boot menu to the session menu takes an extremely long time, several minutes. The three graphic points in the middle on a black background suddenly become confusing characters, then comes: Starting User Login Management... [ OK ] Finished Hold until boot process finished up. [ OK ] Finished Terminate Plymouth Boot Screen. [FAILED] Failed to start User Login Management. See 'systemctl status systemd-logind.service' for details. [FAILED] Failed to start User Login Management. [FAILED] Failed to start Load Kernel Module drm. [FAILED] Failed to start User Login Management. [FAILED] Failed to start Load Kernel Module drm. [FAILED] Failed to start User Login Management. After that Debian GNU/Linux 11 x2gothinclient tty1 x2gothinclient login: After that ultimately, the session menu appears graphically correct in the upper left corner, but much too small, as if the screen size was not recognized. Or is there somewhere a setting option for the size? If you select a session, the session will be opened correctly in full screen. The termination (shutdown) of the session also takes a lot of time, until the small session menu. What can be the reason? Greetings, Olaf (Tested in the preview window of vmware esxi client and locally with a real client.)

pxe-boot: unable to locate configuration file
by Olaf 19 Dec '21

19 Dec '21

Hello! I have set up a new server with an Ubuntu offshoot (bodhi). The client reports correct IP / Mask / DHCP IP / Gateway IP from dhcpd.conf when booting via pxe, but then: "PXELINUX 6.04 PXE 20191223 ... Anvin ... Unable to locate configuration file" /etc/dhcpd.conf: next-server 192.168.3.8; filename "/pxelinux.0"; interface ens160; Connecting from another PC with x2go client works. I've been sitting there for hours and can't get any further. Would be great if someone could help me. /etc/default/isc-dhcp-server: INTERFACESv4 = "ens160" /etc/exports: /opt/x2gothinclient/chroot 192.168.3.0/255.255.255.0(ro,async,no_root_squash,no_subtree_check) /srv/tftp/pxelinux.0 => /usr/lib/PXELINUX/pxelinux.0 Greetings, Olaf

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

Stop pxe-Server
by Olaf Staubus 01 Dec '21

01 Dec '21

Hello! How can I stop the pxe-server (only the pxe function)? I have installed a new Linux server with x2go and would like to test this parallel to the old Linux x2go server, but the new one does not accept the old pxe server. Since at that time I installed the x2go server and the pxe server together on one, I only want to be able to stop / start the pxe-function of the old one to test the new one. Would be great if someone can help. Greetings, Olaf

Dear All, I am new to X2go and to this emailing list. I have used it successfully for a couple of weeks. Then, once, I got the following error message while attempting login (windows10): Failed to start X2Go Agent session with ID xxxxxxx. X2Go Agent terminated unexpectedly. Aborting session startup. I tried to 1. restart PC 2. unistall-reinstall 3. delete session-recreate session 4. exit putty-re-entering I have no more attempts to do. I have used other clients before, and for one of those this sometimes would happen. What I was doing was to -kill geometry in putty and then re-do one. Is there something similar I can do here? I tried to visualize the Archive of this mailing list but I could not find a way to search previous posts. I am lost. Any help would be highly appreciated. Thanks!!!

Unable to start a desktop

Hello, I'm trying to repair the packaging of x2go in Mageia. It was functional in Mageia 7, but this is no more the case in Mageia 8 or cauldron (development version). I have tried 2 clients: x2goclient 4.1.2.2 and pyhoca-gui 0.6.1.1 packaged for Mageia 8. For the server, in a virtualbox VM, I tried to install the master version of x2goserver; through make && make install. I had to change the rights to add write credential on /var/lib/x2go and /var/lib/x2go/x2go_session I use also nxagent-3.5.99.25-1.mga8 and nxproxy-3.5.99.25-1.mga8 packaged for Mageia 8. Thus I have linked xgoagent to /usr/lib64/nx/bin/nxagent Using pyhoca, I can establish the session with the VM, either with the main user or with a test user, using password. But when I try to launch the desktop or a single application like Terminal, this fails. In the journal of the server, i get: sshd[96864]: Accepted password for test from 192.168.1.14 port 35740 ssh2 systemd-logind[683]: [🡕] New session c25 of user test. systemd[1]: Started Session c25 of user test. sshd[96864]: pam_unix(sshd:session): session opened for user test by (uid=0) /usr/local/bin/x2gostartagent[97691]: successfully started X2Go Agent session with ID test-93-1636213441_stDLXQt_dp24 sshd[96871]: error: connect_to 127.0.0.1 port 51346: failed. sshd[96871]: error: connect_to 127.0.0.1 port 51346: failed. In the same time, I get: this log on the client side: Info: Proxy running in server mode with pid '2878627'. Session: Starting session at 'Sat Nov 6 16:46:21 2021'. Info: Using errors file '/home/yves/.x2go/S-test-93-1636213441_stDLXQt_dp24/session.err'. Info: Using stats file '/home/yves/.x2go/S-93/stats'. Loop: WARNING!

Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Sat Nov 6 16:46:29 2021'. Session: Session terminated at 'Sat Nov 6 16:46:29 2021'. What surprise me is that the client uses 127.0.0.1 as remote server address. I have tried to open all ports on the server, in case where the firewall would be implied, but without more success. I don't understand what goes wrong and what to do to debug or restore the normal behavior.

X2Go server on Fedora 35 KDE

When I try to connect to a F35 LXD VM using x2goclient, I get an error "Cannot Exec startkde". This can be fixed by either running "sudo ln -s /usr/bin/startplasma-x11 /usr/bin/startkde" in the VM or changing the command in x2goclient. When a screen is displayed, it is completely black, with an arrow cursor. I've seen a couple bug reports about black screen, but none seem to be relevant. -- Michael Eager
