No desktop armbian server debian client
by Jeremy Ardley 03 Jun '21

03 Jun '21

My setup is an armbian server and a debian client. Both are up to date with the latest releases of all software. I have just now installed the latest distro versions of x2go I configured my client to use XFCE and ensured xfce was installed on the server The server starts fine and I can connect from the client and get prompted for password. I can see the session on the server using ps ax 4504 ? Ss 0:00 bash -l -c echo "X2GODATABEGIN:f32ca5bd-29b1-4f62-bad1-47ca4d1fd28a"; export PATH="/usr/local/bin:/usr/bin:/bin";export TERM="dumb"; x2goresume-session jeremy-50-1622673380 4507 ?

username sessions begin even after reboot without login on Ubuntu 20.04
by h i 26 May '21

26 May '21

Hello, Recently working on a new system using x2go on Ubuntu 20.04 linux. Noticed something different that we never experienced previously on 18.04. Reboots usually clear all sessions per user. After reboot on 18.04, you would see the following output from the linux command: %ps -elf | grep username 4 S username xxxx 1 0 80 0 - xxxxx - 15:20 ? 00:00:00 /lib/systemd/systemd --user 5 S username xxxx xxxx 0 80 0 - xxxxx - 15:20 ? 00:00:00 (sd-pam) However, after reboot on the Ubuntu 20.04 system, I see the following output: 4 S username XXXX 1 0 80 0 - XXXX - 20:44 ? 0:00:00 /lib/systemd/systemd --user 5 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 (sd-pam) 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/bin/pulseaudio 0 S username XXXX XXXX 0 99 - - XXXX - 20:44 ? 0:00:00 /usr/libexec/tracker-miner-fs 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/bin/dbus-daemon --session --address=systemd: --nofork --nopidfile --systemd-activation --syslog-only 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfsd 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfsd-fuse /run/user/1020/gvfs -f -o big_writes 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-udisks2-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-gphoto2-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-afc-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-mtp-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/gvfs-goa-volume-monitor 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/goa-daemon 0 S username XXXX XXXX 0 80 0 - XXXX - 20:44 ? 0:00:00 /usr/libexec/goa-identity-service This behavior occurs after login to x2goclient for just one time. The usernames appear in the "top" commmand output with goa-identity-se process despite not logging for a x2goclient session after a reboot. Is there some setting one can change in x2go for Ubuntu 20.04, so these processes aren't running if a person hasn't logged in x2goclient session after reboot? Thanks. h.

Request for assistance - x2go HTML client
by Jan Bergner 22 May '21

22 May '21

Hello all, I am trying to set up the x2go HTML client on a Debian server following this instruction: https://wiki.x2go.org/doku.php/wiki:advanced:x2gohtmlclient My setup is done with Ansible, so the setup can be reproduced. The git repo containing the role can be found here: https://gitlab.com/jbergner/ansible-x2go-htmlclient Right now, it should be considered a BETA version (using snakeoil-certificates, etc.), but that is not the point. The x2go HTML client is accessible and it seems to be starting a session. However, this session is closed shortly after the initialization. Unfortunately, I cannot seem to find out, why. May be, someone can help? From start to end of the session, I get the following in the nginx access log: 192.168.122.1 - - [10/May/2021:22:38:57 +0200] "GET /assets/x2go-plugin/IMG/x2gobg.svg HTTP/1.1" 200 10261 "https://192.168.122.126/assets/x2go-plugin/" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 192.168.122.1 - - [10/May/2021:22:39:04 +0200] "POST /assets/x2go-plugin/RPC/x2gorpc.cgi HTTP/1.1" 200 2180 "https://192.168.122.126/assets/x2go-plugin/" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 192.168.122.1 - - [10/May/2021:22:39:19 +0200] "GET /x2gows/50001 HTTP/1.1" 101 17 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" nginxes error log: 2021/05/10 22:38:58 [error] 1516#1516: *2 FastCGI sent in stderr: "Scalar value @out[2] better written as $out[2] at /var/www/html/assets/x2go-plugin/RPC/x2gorpc.cgi line 79.

AFAIKS freenode is not the network of choice anymore: https://mniip.com/freenode.txt So should we move to libera? Or elsewhere? Or drop the chat altogether? Uli

Session terminated instantly, seemingly with no errors
by Matteo Guareschi 19 May '21

19 May '21

Hello, I have been trying to figure this out for a while now. Every time I start a session from my client (arch) to my server (arch xfce), the session seems to start fine, but terminates instantly. The client reads: Info: Proxy running in server mode with pid '11128'. Session: Starting session at 'Sun May 16 15:24:13 2021'. Info: Using errors file '/home/matteo/.x2go/S-matteo-50-1621203851_stDstartxfce4_dp24/sessions'. Info: Using stats file '/home/matteo/.x2go/S-50/stats'. Loop: WARNING!

Assuming agent session. Warning: Unrecognized session type 'unix-kde-depth_24'. Assuming agent session. Info: Using ADSL link parameters 1408/24/1/0.

And the error files in the S-matteo-50-[...] directory are sessions, options and a spool dir. Sessions only says what versions were found. On the server side in the C-matte-50 directory session.log gives the rather uninteresting errors: Error: keyboard file not created: Is a directory Error: Aborting session with 'Could not open default font 'fixed''. before terminating. The system log itself /var/log/user.log does not report any errors, but only terminates the session. The clients file reports only: error opening security policy file /usr/local/lib/nx/X11/xserver/SecurityPolicy At this point I have exhausted my resources. I have tried the client from a different OS and the result is the same. From what I understand the fixed font error is most likely a red herring, but I have installed xorg-fonts-misc for what it's worth, with no difference. Lastly I should mention that the server runs xfce4 fine on the machine itself (using dbus-launch also makes no difference). I would really appreciate any help. -- Matteo Guareschi

Re: [X2Go-User] Removing "Suspend X2go Session.." in Ubuntu Mate desktop System Panel , 20.04
by h i 16 May '21

16 May '21

Okay, Thanks. I was able to get it to suspend using both methods. That was a mistake on my part. Too many x2go client windows open. Using the command line x2gosuspend-session worked and properly suspended the session. Clicking on the item from the mate desktop menu worked as well. Thanks for providing insight on how this menu item is now coded in the Mate-panel applet with 20.04. It looks like it can't be removed easily. Since it just provides an additional option for suspending the session, removing it most likely isn't necessary. Thanks again. h ________________________________ From: Mike Gabriel Sent: Sunday, May 16, 2021 3:34 PM To: h i Cc: x2go-user(a)lists.x2go.org Subject: Re: [X2Go-User] Removing "Suspend X2go Session.." in Ubuntu Mate desktop System Panel , 20.04 Hi, On So 16 Mai 2021 21:08:45 CEST, h i wrote: > Hello, > > How can you remove the "Suspend X2Go Sesseion..." item from the > Ubuntu Mate System panel? > > [cid:8d0d43b2-6e97-4a50-87a4-d76edbc29ab6] > > In Ubuntu 18.04, this was linked with x2gomatebindings.

The "Suspend X2Go Session..." menu item is now coded into the corresponding MATE panel applet (via librda). Currently, there is no "switch" to disable it, but it could be a feature request. The other issue is that X2Go Client does not recognize the session suspension properly when done from inside the session, it seems. If you open a terminal in the X2Go session and issue the command x2gosuspend-session on the command line, do you observe the same behaviour? (i.e. session goes away, but X2Go Client does not get it?)

Removing "Suspend X2go Session.." in Ubuntu Mate desktop System Panel , 20.04
by h i 16 May '21

16 May '21

Hello, How can you remove the "Suspend X2Go Sesseion..." item from the Ubuntu Mate System panel? [cid:8d0d43b2-6e97-4a50-87a4-d76edbc29ab6] In Ubuntu 18.04, this was linked with x2gomatebindings. Uninstalling the bindings removed it. However, with Ubuntu 20.04, I could not locate x2gomatebindings in the Ubuntu repository. I want to remove it because we don't need it and it doesn't work well with x2go client. Clicking on the item makes the desktop session disappear, but the x2go client window says the session is still running and doesn't disappear. Thanks. h.

Thanks, Mike, I already had the executable so the "yum update --skip-broken" it proposed did the trick but I was flagging it as a possible package dependency issue. I've never done package building but for folks who build the x2go rpms, changing the dependency from it needing the "base64" package to it needing the "coreutils" package would resolve the: > x2goserver-4.1.0.4-0.0x2go1.0.git20210418.1930.heuler.el7.x86_64 > (x2go-nightly-epel) > Requires: base64 resulting in a smoother install.

Huge session.log files in user /tmp folder
by Mark Lamers 11 May '21

11 May '21

Hi, We run a x2go server for scientists who while worjk with python and R scripts on large data sets. However some user create immense large session logs in /tmp/.x2go-$user/$user-XX-XXXXXXXXXXX_stDMATE_dp32/session.log. These a sparse files but a certain point fill up out /tmp partition. Is there a way to reduce these files or set a max size per user? Regards Mark

Automatically select New session when there are already other sessions from other client
by Bambang P 07 May '21

07 May '21

How can we force the user to select New session when on connect there are already other sessions from other client? To be clear, here is the scenario 1. HQ computer run the x2go server 2. Computer 1: a supervisor run x2go client and accessiong the server 3. Computer 2 want to access the server, after authenticate the connection he is then presented with Select session form with the computer 1 session listed. If the he double click the computer 1 session, he is hijacking the computer 2 session. How can I prevent this situation? Is there a way to force so he can only create a new session? -- Bambang P http://bpranoto.blogspot.com

Wayland launch scripts being used?
by Jeff Sadowski 04 May '21

04 May '21

So I'm not sure why so many of my desktops in Fedora have stopped working with x2go but I heavily suspect it is them transitioning all desktops to wayland. I know gnome still has an option to select xorg from the console but x2go does not provide any clarification on this kind of selection. Maybe if I understood how the server side selects the script to run to start the desktop depending on the selection from the client side I could help the package maintainers make things easier for x2go users. All I know for certain is: I was using XFCE desktop in Fedora 33 when I upgraded to Fedora 34 XFCE became unusable over x2go. I started trying other desktops and noticed they do not act right. Gnome over x2g on fedora 34 doesn't even start. KDE seems to have some issues. Mate seems to work.

Frozen Login Screen "kscreenlocker_greet"
by Thomas Roebbenack 04 May '21

04 May '21

Is there any problems known about frozen sessions at reopen it after a some time? - This problem occurs since 3 days now, don't know why and what exactly happen (probably system updates). Before it worked without problems. - I working on "Ubuntu 20.04.2 LTS" and KDE Plasma Desktop (5.18.5) (Framework 5.68.0, QT 5.12.8) What exactly happen: - Open a session working as expected (with opened Session/Window the Screenlocker occurs, but I can move the mouse and enter the password) - After closing the window (the session runs in the background), I can reconnect after a short time ~10 Minutes, the screenlocker occurs, but I can move the mouse and enter the password. - But, after a longer time (don't know exactly how long), If I reconnect the screenlocker occurs, but the screens seems to be frozen. I can move the mouse, nothing happen, try to enter some keys, nothing happen. Looks like the screensaver is dead. The CPU load of 1 core is 100% (kscreenlocker_greet + a x11 process). -> The only thing that worked at the moment, try to open a second session gives me the possibility to close the first one, than I can reconnect. But I have to kill (-9) the both running processes to stop feed my CPU load. -> Disable the screensaver is no option, because there exists a directive to use it. Any suggestions? Any Ideas? Thank you in advance. Thomas

mouse 1 cm too low
by richard lucassen 17 Apr '21

17 Apr '21

Hello list, I have run x2go for many years now without any problem. I have two different servers running Debian testing and x2go 4.1.0.3-5, multiple clients running the same OS and x2go client. I run WindowMaker both on client and servers. This has worked for many years. Weird thing: the active clicking point for the mouse is 1 cm above the mouse. Restarting client and server does not make any difference. AFAIK these x2go versions have not changed (underlying libraries might have of course). I tested this on a few clients: same problem. It make x2go almost unusable. Anyone a hint what to test and where to look for this weird issue? R. -- richard lucassen http://contact.xaq.nl/

Multiple connexion with the same user name
by kanssoune.saliya＠external.tractebel.engie.com 06 Apr '21

06 Apr '21

Hello everyone ! I would like to configure remote login to CentOS 7 servers using x2go and allow multiple login with the same user i.e. many users use the same ID and password to log in at the same time. Does x2go allow it? I explain below a little bit more our infra : * We use NIS as user authentication * We have more than 10 different Linux workstations * Each colleague can connect on every workstations * We use generic account for some purpose i.e. many users use the same ID and password Do you thing that this is possible to configure with x2go? If yes, what are the steps to follow? What desktop environment (MATE, XFCE, GNOME ...) will be best adapted? Thanks! ENGIE Mail Disclaimer: http://www.engie.com/disclaimer/

One application (Digikam) fails, apparently randomly
by Chris Green 02 Apr '21

02 Apr '21

Well I'm very confused now, I thought I could see a pattern but I can't. I'll report what I have discovered so far though. I'm running x2gclient 4.1.2.2 (as installed from the Ubuntu repositories) on my xubuntu 20.10 laptop. I'm running the server on my xubuntu 20.10 desktop machine, again just as installed from the Ubuntu repositories:- x2goserver: 4.1.0.3 x2goserver-common: 4.1.0.3 x2goserver-extensions: 4.1.0.3 x2goserver-fmbindings: 4.1.0.3 x2goserver-printing: 4.1.0.3 x2goserver-x2goagent: 3.5.99.24 x2goserver-xsession: 4.1.0.3 I have been trying a mix of three types of session, as follows (with results):- 1 - A small Python GUI program as a 'Single Application', this always runs without any problem at all, it just works every time. 2 - An XFCE session, this works every time and doesn't cause any major issues but it does occasionally pop-up windows in the server session as follows:- A window saying "Authentication is required to create a colour profile" and I have to enter my sudo user password. After the above pop-up I sometimes get a second one saying "Authentication is required to operate a colour managed device" The above two pop-ups only appear occasionally, usually the XFCE session just starts up and runs normally. Once I've entered my sudo password in response the session runs OK. 3 - A Digikam session as a 'Single Application', this does work sometimes but more often it appears to start OK, then xfwm4 on the *client* crashes and the Digikam session disappears even though it is still running on the desktop machine. I can't see any consistent reason for when it does work or when it doesn't work. Digikam is running from a big Appimage. Running digikam in an XFCE session running in x2go works perfectly, or at least I've not managed to crash it ever. It's only when run as a 'Single Application' that it fails. I guess I can just run Digikam in an XFCE session but I'd like to be able to just run Digikam. It's frustrating that it sometimes works but I can't see what is needed for it to work. As I said elsewhere I've run memtest on the desktop machine for two whole passes and it showed no errors. I'm happy to add debug flags to either end to see if it's possible to diagnose this. -- Chris Green

Error on resume/start: Call to bind failed for NX. Error is 98 'Address already in use'.
by Simon Beißer 31 Mar '21

31 Mar '21

Hello, We are frequently experiencing problems, especially with the session resume but also with the start of sessions. On x2goclient the session is terminated immediately after login with "finished". The session.log shows the following error message: Loop: PANIC! Call to bind failed for NX. Error is 98 'Address already in use'. Error: Call to bind failed for NX. Error is 98 'Address already in use'. After several login attempts or after a short wait the login is possible again without any problems. We run several X2Go installations. The problem occurs across all of our installations. We are using Ubuntu 20.04 with XFCE and the latest NXAGENT 3.5.99.26. Does anyone know this behavior? Is there already a solution?

by Carlos Alfaro 30 Mar '21

30 Mar '21

I have noticed that I can log on to a pc which has an x2go server but only after I log on, after reboot I would have to log on to get access. Any way to enable it so I can log on to the server without having to sign on first? Sort of how google remote desktop works? thanks

x2go to access Linux - issues with graphical updates
by Anonymous Japhering 18 Mar '21

18 Mar '21

X2Go Client v. 4.1.1.1 (Qt - 5.9.5) Guest Linux Mint 5.4.0-66-generic #74-Ubuntu SMP x86_64 Host Linux Mint 5.4.0-67-generic #75~18.04.1-Ubuntu SMP x86_64 Guest is where the issue is occurring.. host is where I'm working from ( x2go client is running) On Guest, I open the Linux Mint update manager. If I need to do nothing more than approve update, everything works as expected. However, if I want to change software sources or perform a version up it fails. Both items require a secondary window to be open, which doesn't happen, at least in x2goclient. Computer in question has no monitor and is only accessed through x2go (my display port adaptor died). Thoughts or suggestions ?

Different display ratio at server and client
by Zoltan Tibenszky 10 Mar '21

10 Mar '21

Hello everybody, I would like to use X2Go to get access to my desktop remotely. The server has a two monitor setup and I would like to access this desktop through a laptop. So far the X2Go client has shrunk the display horizontally, which makes it hard to work with it. I am looking for a solution to overcome this issue. Currently both the server and the client runs Xubuntu 20.04 LTS. There are two simple intuitive ways I can think of: 1. show only one monitor and have a bindkey/button to switch between displays 2. open the remote desktop in a window with scrollbars Is there anything similar already implemented? Or are there any other ways to make using remote desktop with different display resolutions practical? Thanks, Zoltan

Windows 10 Error - X.Org Server did not launch correctly after 4 tries
by Rich Sakalas 03 Mar '21

03 Mar '21

Hello, I am trying to use X2Go to access various servers from my Windows 10 64 Bit laptop. Occasionally it works great. Mostly when trying to start a session I receive the following error: " X.Org Server did not launch correctly after 4 tries. Please check your installation." I'm running Windows 10 Enterprise 64 bit Version 20H2 Build 19042.804. I've tried uninstalling and reinstalling, this does not fix the problem. I've attached the output of the debug log from when I've tried to run it this morning, but I'm having a hard time deciphering it. Any ideas on how to help resolve this would be appreciated, this is a fantastic tool. Thank you, Rich Sakalas

accessing windows that fall off the screen
by Michael Ashley 27 Feb '21

27 Feb '21

Hi folks, Another question for you: sometimes I reconnect to an x2go session from a computer that has a smaller display than the one that I previous connected from. The problem is that some of the windows now fall partially or fully off the display. The partial ones are usually accessible by clicking and dragging their borders until enough of them appears so that the window can be dragged back in to full view. The usual X11 keystroke/mouse combination for dragging a window isn't passed through to the x2go session, so this only works on the high-level x2go window (presumably there is a way of creating a different keystroke/mouse combination that is passed through). But for windows that fall completely off the screen, I can't see how to access them. Any ideas? I'm using xfce. Regards, Michael

Hello, I have been using X2go client only iMac connecting to a Debian 10 linux box successfully for about a year. Recently it has stopped working.

I have subsequently removed this new version of Xquartz and installed the same version as on my laptop, 2.7.11 but I still am unable to connect. I have also removed X2go client and reinstalled but still no joy. Any hints or ideas would be much appreciated. Many thanksTrevor

nxagentReconnectFailedFonts: does anyone have a solution?
by Michael Ashley 27 Feb '21

27 Feb '21

Hi folks, Last week I connected to a long-running x2go session using a different computer than I normally do. It worked fine. But later that day when I returned to my usual computer, I ran into the bug where the session would start up, but then disconnect within about a second, with the error messages: > nxagentReconnectFailedFonts: WARNING! Font server tunneling not retrieved. > nxagentReconnectSession: WARNING! Unable to retrieve all the fonts currently in use. Missing fonts have been replaced. A google search shows that this bug was reported 7 years ago, but no solution appears to be forthcoming, apart from trying to adding fonts. But with over 1000 fonts on the server, I have no idea how to find which ones need adding. Are there any ideas out there for how to address this problem? It is certainly frustrating to be unable to connect to a running x2go session, and having to terminate it on the server. Regards, Michael

script to automatically restart x2go client session after coming out of suspend
by Michael Ashley 26 Feb '21

26 Feb '21

Hi folks, I thought that some of you might be interested in a small script that I use to automatically restart an x2go client session after returning from suspending the client computer: #!/bin/bash while true; do pyhoca-cli -R NEWEST --link wan -g 3768x2123 --pack 16m-png-jpeg-9 user@computer & while ! wmctrl -r X2GO -e 0,0,0,3768,2123; do sleep 1; done echo sleeping sleep 10 wait done The idea is to use pyhoca-cli to handle the connection. The "wait" line waits until the pyhoca-cli subprocess ends, which happens shortly after the computer comes out of suspend. The "wmctrl" line is just to resize the window to fit my display. Change the numbers 3768x2123 to suit. The "sleep 10" I had in there while debugging to avoid runaway creation of sub-processes, which is capable of crashing the x2go server session. The nice thing about this script is that I can be up and running with the x2go client session within less than 10 seconds or so of coming out of suspend, without having to tediously interact with the x2goclient GUI. In turn, this means that there is almost no friction in suspending/resuming my desktop computer, with consequent power savings. The script could be improved by starting a new session if there is no existing one. Regards, Michael

The first time it told me to run debuginfo-install nxagent-3.5.99.25-4.el7.x86_64 so I did that. Each time after I attach the debugger then my x2go window is frozen so I cannot try changing anything. When I quit the debugger then the x2go window crashes.

Re: [X2Go-User] Cross-session copy/paste issue
by Jonah Benton 24 Feb '21

24 Feb '21

Hi Uli, Thank you- concur about images- in the past, copy-paste of them only worked within a session, not across. My workaround was to paste-save to /tmp on the host and then open saved image from another session. But nearly all copy-paste for me is text / URLs. Re versions of nxagent: Currently: [admin@localhost ~]$ dnf list installed | grep nx nx-libs.x86_64 3.5.99.26-1.fc33 @updates nxagent.x86_64 3.5.99.26-1.fc33 @updates nxproxy.x86_64 3.5.99.26-1.fc33 @updates Previously version release schedule https://www.spinics.net/lists/fedora-package-announce/msg288622.html * Fri Jun 19 2020 Orion Poplawski <orion@xxxxxxxx> - 3.5.99.24-1 - Update to 3.5.99.24 * Sat Feb 1 2020 Orion Poplawski <orion@xxxxxxxx> - 3.5.99.23-1 - Update to 3.5.99.23 * Wed Jan 29 2020 Fedora Release Engineering <releng@xxxxxxxxxxxxxxxxx> - 3.5.99.22-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_32_Mass_Rebuild So I was previously running what Fedora calls 3.5.99.24. I can try to downgrade if there is an earlier 3.5.99 on Fedora 33- will that matter? Happy to give a go at a replacement build. I did just note two additional behaviors- 1. cross-session paste does *eventually* complete -copy of text 1 in session 1 -attempt to paste in session 2 -observe session 2 window freeze -switch to host window -paste into host window (success) -select and recopy in host window -switch back to session 2- paste of text 1 had completed So the paste took about 5 seconds 2. cross-session paste payload can be replaced in flight -copy of text 1 in session 1 -switch to session 2 -attempt to paste (text 1 into session 2) -observe session 2 window freeze -switch to another window in session 2 -select and copy text 2 (in another window in session 2) -switch to the session 2 window attempting to complete the original paste -note that the paste completed- but using text 2, not text 1 Thanks again!

X2GO Crash When Resizing columns in Cliosoft Sos
by Joe W 23 Feb '21

23 Feb '21

I am using a program called Cliosoft SOS. It has a window that displays in columns like an Excel file. When I resize one of the columns then my X2GO session window crashes. The start window where I pick which session to start stays running. There is a horizontal scroll bar to move the columns sideways. When I drag that then the X2GO window crashes. I can resize the entire SOS window without any problems. I do not see this sort of behavior in LibreOffice Calc. I have attached the session log and the client debug console output showing a few of these crashes. My client is v. 4.1.2.2 on Windows 10. I am connecting to a CENTOS 7 system running X2GO 4.1.0.3-9 server which came from the Epel repo. Is there some way to fix this or is it a bug that I should report? Is there any additional information that I should gather? Anything I should ask the software developer?

Cross-session copy/paste issue
by Jonah Benton 20 Feb '21

20 Feb '21

Hi folks, Let me first say thank you to X2Go maintainers- I happened upon X2Go about 6 months ago when figuring out how to switch my workflow from Fedora VMs on MacOS to distinct desktop environments on Fedora. It is such a profoundly excellent tool. Thank you for your efforts. Now- to describe a problem that just cropped up, hoping someone can help me debug. I have been running Fedora 32 - XFCE on a Thinkpad, simultaneously running 7 distinct local X2Go sessions under 7 different host users. Each session's window resides within its own XFCE logical desktop, and I switch between them with the switch desktop hotkeys. X2Go sessions are configured to support bidirectional copy/paste, and generally it works seamlessly to copy text or images from apps in one session's window to another or to/from the host. Last night I upgraded to Fedora 33, with the requisite updates to X2Go. Now, copy/paste is reliably broken in one area: * from host into any session still is fine * from session into host still is fine * from a session into the same session still is fine * from one session into another session no longer works On failed pastes- where the copy was from one session and the paste is another session- when the paste recipient is a browser (Chromium, Firefox, whatever), sometimes the recipient browser tab temporarily locks up trying (and failing) to retrieve the paste material. All X2Go sessions are still configured for bi-directional copy-paste. [admin@localhost ~]$ x2goclient --version x2go-WARNING-1> English language requested, not loading translator. x2go-WARNING-1> English language requested, not loading translator. 4.1.2.2 [admin@localhost ~]$ x2goversion : 3.2.0.0 : 4.1.0.3 : 4.1.0.3 : 3.2.0.0 : 4.1.0.3 : 3.5.99.26 : 4.1.0.3 Any thoughts on tracking down the issue? Thanks again, Jonah

Shared folder fails silently on client side?
by James Bowery 20 Jan '21

20 Jan '21

For some reason the automounted shared folder is no longer being shared. Moreover, manually mounting doesn't work either. Yet there are no error messages in the X2Go CLient status window (Session ID:... Server:... Username:... Display:... Creation time (is blank?) and Status running). I'm not exactly sure where to look on the Ubuntu server for diagnostics, but it seems the client side should not be so silent under both automount and manual mount.

Single Application session fails

18 Jan '21

I am running x2goclient on my laptop and the x2go server is on my dekstop, both systems are running xubuntu 20.10.

The application *is* still running but is not displayed.

pyhoca-cli seems very broken on xubuntu 20.10

Having fixed the missing python3-invoke module pyhoca-cli now crashes in all sorts of other ways on my xubuntu 20.10 system.

x2go session crashes xfwm4
by Chris Green 18 Jan '21

18 Jan '21

I've recently upgraded my system to xubuntu 20.10 and x2go sessions now crash the xfwm4 window manager. After restarting xfwm4 from a terminal window I see the following crash report when I run another x2go session:- xfwm4:15183): Gdk-ERROR **: 11:27:33.867: The program 'xfwm4' received an X Window System error. This probably reflects a bug in the program. The error was 'XSyncBadAlarm'. (Details: serial 213260 error_code 135 request_code 134 (SYNC) minor_code 11) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Trace/breakpoint trap (core dumped) Is this a bug in xfwm4 or in x2go? -- Chris Green

Missing dependency for pyhoca-cli

I just installed (using synaptic, i.e. apt) pyhoca-cli on my xubuntu 20.10 system and it dies with a ModuleNotFoundError :- chris$ pyhoca-cli esprimo Traceback (most recent call last): File "/usr/bin/pyhoca-cli", line 439, in <module> parser, args = parseargs() File "/usr/bin/pyhoca-cli", line 397, in parseargs ssh_host = ssh_config.lookup(a.server) File "/usr/lib/python3/dist-packages/paramiko/config.py", line 223, in lookup options = self._lookup(hostname=hostname) File "/usr/lib/python3/dist-packages/paramiko/config.py", line 250, in _lookup or self._does_match( File "/usr/lib/python3/dist-packages/paramiko/config.py", line 387, in _does_match raise invoke_import_error File "/usr/lib/python3/dist-packages/paramiko/config.py", line 36, in <module> import invoke ModuleNotFoundError: No module named 'invoke' Easily fixed by installing python3-invoke but presumably there's a missing dependency.

Hello! I have x2goserver 4.1.0.3 (running on Linux Mint ver 20.1 with Mate) and two x2goclients (ver 4.1.2.1 on Debian Stable and ver 4.1.2.2 on Archlinux). Server is behind firewall and I am connecting to it via 'ssh -L' tunnel through machine, which is visible to both side. SSH connection from both clients works fine. But if vhile x2go connection from Debian works, I cannot connect from Archlinux and I do not know why - can you help me? In the attachment is two "--debug" client's outputs. The beginnig looks fine on both, but in the "client-arch-bad" outputs somewhere at the line 91 it started to go wrong. Many thanks for help. Jana

X2go Server Float Windows?
by Rodrigo José Petreça 07 Jan '21

07 Jan '21

Hello Everybody! Please, i have a question! I am migrating an internal server, from fedora 11 + freenxserver, to debian buster + x2go server. The basic are working, but we have a custom application, it's a very simple application. I need to export xterm or gnome-terminal, and execute bash script, this script calls a simple text menu. The menu contains options, and this option calls some programs. on the freenx server i can export terminal and other applications in floating and separate windows, but i can't do this on x2go. When I access the x2go server from the x2go client, I can see all applications on 1 window only, like vnc access. It's possible to configure x2go server or client to float and separate windows? Thanks...

X2Go fails to connect when SSH config contains multiple jump hosts
by Konrad, Martin 08 Dec '20

08 Dec '20

Hi, I have a few hosts in my ~/.ssh/config file which have ProxyJump lines specifying _multiple_ jump hosts: Host foo ForwardAgent yes ProxyJump first.example.com, second.example.com It seems like X2Go doesn't like this kind of configuration. I complains when I try to establish any connection (even when trying to connect to other hosts which don't have a line like this): "Cannot connect to first.example.com:22 Failed to process system configuration" Everything works fine in cases that require only a single jump host. As far as I can tell from the ssh_config (5) man page my configuration with multiple jump hosts is valid. Any suggestions how to deal with this?
