X2Go: The Gathering 2020 AKA V/RUS (2020-09-18 - 2020-09-20) will take place at Stuttgart's hackerspace "shackspace"
by Stefan Baur 18 Aug '20

18 Aug '20

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-ML-1@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. Sincerely, Stefan Baur, "X2Go: The Gathering" event organizer -- 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

Big black borders on windows in remote MATE desktop
by Kees Bakker 18 Aug '20

18 Aug '20

Hi, Since today I have an annoying phenomena on my remote MATE desktops. All windows have a big black border around it. This happens on all remote MATE desktops I tried. Even `xeyes` has that ugly black border. It doesn't happen with LXDE. You might ask: what changed? Well, a power outage, that caused a reboot (which I normally don't do). No package updates that I can see (which could have an influence). The question is: is it my local X2GO client causing this? Or is it something remote (and then, all remotes)? The border is not done by the remote window manager. I can switch themes, but the black border is always there. The window snapping to the screen edges does not use the outside of the black border. It really looks weird, and it annoys me. Especially, not knowing what caused it, and where to look to solve it. -- Kees

error
by richard lucassen 13 Aug '20

13 Aug '20

Hello list, server: Debian testing 4.1.0.3-5 client: Debian testing 4.1.2.2-2 Since this morning I get this (large) error message on *all* clients, connecting to *one* particular server that has worked for many years. I have another server, same OS, same version: no problem. The problem occurs when connecting to this perticular server. AFAIUK there has been no recent update for x2go in Debian testing. I removed all user x2go files, I removed x2go files in /var/lib/ and finally I purged the whole package, ran "apt autoremove" and purged all packages status "rc". Then I reinstalled the x2goserver: same problem. I fear it is some other package that messes up the functionality. Anyone a hint where to start? This is the message (sorry, it's bit a mess): Connection failed. /usr/lib/x2go/x2gocheckport: line 125: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330. /usr/lib/x2go/x2gocheckport: line 58: /dev/fd/62: No such file or directory /usr/lib/x2go/x2gocheckport: line 87: /dev/fd/62: No such file or directory DBD::SQLite::st execute failed: UNIQUE constraint failed: used_ports.port at /usr/share/perl5/X2Go/Server/DB/SQLite3.pm line 330.

x2go does not connect from Raspberri pi to x2go server
by Jeroen Baten 12 Aug '20

12 Aug '20

Hi, I work with x2go on a daily bases for my usual desktop. Made an Intel NUC into a thin client and connect to my main server. I love this program. Even audio and video streaming work. (well, not Zoom or Teamviewer, but that's a story for another day) Now I am trying to do the same from a Raspberry Pi model 4 with 8 Gb and Rapsbian OS, version 10.4. I use 4.1.2.2-0x2go1+git20200213.1926+10.main.1 armhf on the client and x2goserver 4.1.0.3-5 on Ubuntu 20.04 When I start the client and make a connection the same as from my other client it just hangs. No session will open on the client and the gui stays grayed-out/disabled/no-focus like. I increased the logging in the server side but that made no difference. I started x2goclient with the --debug flag but I can't seem to find the source of the error message. But I do see an error message. I just don't know what to do with it. x2go-DEBUG-../src/sshmasterconnection.cpp:687> User authentication OK. x2go-DEBUG-../src/sshmasterconnection.cpp:1708> LOGIN CHECK:"LOGIN OK " x2go-DEBUG-../src/sshmasterconnection.cpp:1711> don't have interaction x2go-DEBUG-../src/sshmasterconnection.cpp:1744> LOOP FINISHED x2go-DEBUG-../src/sshmasterconnection.cpp:1748> No interaction needed, continue session x2go-DEBUG-../src/sshmasterconnection.cpp:702> Login Check - OK x2go-DEBUG-../src/onmainwindow.cpp:2947> SSH connection established. x2go-DEBUG-../src/onmainwindow.cpp:3374> Continue normal X2Go session x2go-DEBUG-../src/sshprocess.cpp:199> Executing remote command via SshProcess object 0: "x2golistsessions" x2go-DEBUG-../src/sshprocess.cpp:213> this=SshProcess(0xd40950) Running masterCon->addChannelConnection(this, ' "02310883-db4c-4f5f-9dbb-f1566c1c888c" ', ' "bash -l -c 'echo "X2GODATABEGIN:02310883-db4c-4f5f-9dbb-f1566c1c888c"; export PATH="/usr/local/bin:/usr/bin:/bin";export TERM="dumb"; x2golistsessions; echo "X2GODATAEND:02310883-db4c-4f5f-9dbb-f1566c" '); x2go-DEBUG-../src/sshmasterconnection.cpp:1810> Locking SSH channel connection MUTEX. x2go-DEBUG-../src/sshmasterconnection.cpp:1812> Passing new channel connection object to channelConnections. x2go-DEBUG-../src/sshmasterconnection.cpp:1814> Unlocking SSH channel connection MUTEX. x2go-DEBUG-../src/sshmasterconnection.cpp:1977> Creating new channel. x2go-DEBUG-../src/sshmasterconnection.cpp:1990> New channel:0xb1513ce8 x2go-DEBUG-../src/sshmasterconnection.cpp:2065> Executing remote: "bash -l -c 'echo "X2GODATABEGIN:02310883-db4c-4f5f-9dbb-f1566c1c888c"; export PATH="/usr/local/bin:/usr/bin:/bin";export TERM="dumb"; x2golistsessions; echo "X2GODATAEND:02310883-db4c-4f5f-9dbb-f1566c1c888c";'" x2go-DEBUG-../src/sshmasterconnection.cpp:2071> "ssh_channel_open_session failed": "Socket error: No such file or directory" x2go-DEBUG-../src/sshprocess.cpp:478> I/O error: "ssh_channel_open_session failed."" - Socket error: No such file or directory" (0). x2go-DEBUG-../src/onmainwindow.cpp:1527> Close event received. x2go-DEBUG-../src/onmainwindow.cpp:1551> Quitting from tray icon and closing application. x2go-INFO-6> "Closing X2Go Client ..." x2go-DEBUG-../src/onmainwindow.cpp:1370> Saving settings ... x2go-DEBUG-../src/onmainwindow.cpp:1379> Saved settings. x2go-DEBUG-../src/onmainwindow.cpp:1401> Waiting for the SSH connection to finish ... x2go-DEBUG-../src/sshmasterconnection.cpp:764> SshMasterConnection, instance SshMasterConnection(0xdf5958) waiting for thread to finish. x2go-DEBUG-../src/sshmasterconnection.cpp:1908> Disconnecting ... x2go-DEBUG-../src/sshmasterconnection.cpp:1917> Deleting channel connections. x2go-DEBUG-../src/sshmasterconnection.cpp:2222> EOF sent.

x2gokdrive
by Christoph Pleger 06 Aug '20

06 Aug '20

Hello, I am currently at a loss with the use of x2gokdrive. I am sure that I had it working on an X2Go server some days ago, but now the session ends very quickly, without any Xession being started. And I cannot remember to have changed anything on the server side in the meanwhile. Unfortunately, log files are neither created on the client nor on the server side, and when I enable "Show details" in X2GoClient, nothing more the "Status: connecting" and "Status: Finished" is shown.

X2GoBroker with Kdrive
by Christoph Pleger 03 Aug '20

03 Aug '20

Hello, is it possible to use X2GoBroker with Kdrive? In my x2gobroker- sessionprofiles.conf, I have two sections with identical options, with the exception that the first section contains kdrive=false and the second contains kdrive=true. While non-kdrive connections work successfully with the configuration, kdrive connections are aborted. Direct kdrive connections (without broker) to the same destination host work correctly.

X2Go load balancing
by Christoph Pleger 30 Jul '20

30 Jul '20

Hello, I have three questions regarding X2Go load balancing and the X2Go Broker needed for that. The first question is, if it can be avoided that user login data has to be entered twice, once for the broker and once for the X2Go server. Is it possible to configure x2gobroker-daemon so that it forwards the login data it got before to the X2Go server? The second question is if it is somehow possible that with load balancing it is possible that every user can set his or her own connection parameters, like with x2goclient in non-broker mode, with the remote host as only exception. As for example display sizes and internet connection speeds differ between users, it is quite difficult to create so many profiles on the broker machine so that all user wishes are met. The third question is if a kind of load balancing can be achieved that takes into account a) that possibly not all destination hosts have the same hardware power, for example one host may only have 8 CPU cores and 16GB Memory, while another has 64 CPU cores and 256 GB Memory. b) that the real load of a host is not only decided by the number of logged-in users, but also by what the users are doing. Regards Christoph

Massive number of logfile entries
by Craig Morton 30 Jul '20

30 Jul '20

Hi, Newcomer to X2go, set it up on my workstation in the office so I can work remotely. While it's functioning beautifully, I'm noticing a massive number of entries appearing in my system logs, both the secure and messages files. I'm talking several entries per second. Secure is full of constant pam_unix "session closed" and "session open" messages for active X2go connections. Messages is full of system session start information again for active connections. X2go entries in the logs are relatively few and make sense. Why so many entries, and how do I turn them off? Cheers, Craig.

x2go Broker GUI selection issue [command = ]
by Jyoti Kumar 28 Jul '20

28 Jul '20

Setting up passwordless session
by funk minion 24 Jul '20

24 Jul '20

Using windows client 4.1.2.0, I'm wanting to set up passwordless authentication. I've followed these instructions.... https://wiki.x2go.org/doku.php/wiki:advanced:authentication:passwordless-ssh ...but am still receiving a small modal dialog box prompting for an account password."Enter user account password:" In the settings for the session, "Use RSA/DSA key for ssh connection:" points to my local private key file and "Try auto login (via SSH Agent or default SSH key)" is checked Question: Is 'auto login' required for passwordless login? Question: Does the term 'default SSH key' reference the id_rsa key created by the ssh-keygen.exe or something else? Question: Does passwordless login require the use of Pageant or other tools, or can it be accomplished solely with x2go settings? thx.

How to scale remote apps on laptop 4k hidpi displays?
by Leho Kraav 16 Jul '20

16 Jul '20

Hi I'm running a 3840x2400 laptop display in 200% scaled mode, on gnome-shell-3.36. x2goclient-4.1.2.2 UI can be fixed up with QT_AUTO_SCREEN_SCALE_FACTOR=1. But remote apps still launch in native resolution, making everything tiny small. This happens for both Wayland and Xorg-based Gnome session. Is there a solution to getting the remote x2go session match the current scale of local display? Mailing list searches for "hidpi" etc failed to find anything useful. -- Leho Kraav, senior technology & digital marketing architect

Connection failed session ... terminated
by Andrew Munn 13 Jul '20

13 Jul '20

I'm running the Windows client v4.1.2.2. Server is CentOS 8. I connect and double-click on the row here: [image: image.png] Then I get this: [image: image.png] This problem happens frequently on all my servers. I can click "New" and open a session but I can never successfully reconnect to that other listed session. I think deleting something from /tmp fixed this in the past. Sound right? Why does this always happen?

Configure x2go-client to not forward specific key combinations?
by Jonah Benton 10 Jul '20

10 Jul '20

Hi folks, I'm interested in using x2go to: * connect into several individual accounts/machines at the same time * use each remote machine desktop in full screen mode * switch between remote full screen desktops using a specific key combination, which would therefore not be sent to the remote Is this possible? In my initial perusal of man pages and testing I don't see a way to do what seems to me to be the (probably wrong) solution- instruct the x2go-client (in either launch remote desktop mode, or desktop screen sharing mode) to not capture a specific key combination (like control-alt-right arrow and control-alt-left arrow) so that the parent desktop can handle them (e.g. switch between parent-side virtual desktops). I'm using Fedora / XFCE for all systems. Thanks very much in advance! Jonah

Client GUI for connecting to broker
by Iain Hallam 09 Jul '20

09 Jul '20

Hi. I'm considering using X2Go broker to implement load balancing for some Linux servers, but many of our users are on Windows devices. Getting them to run the command line options to connect to a broker is going to be tricky; it would be much more useful if we could get them to click on a button, paste in an address, and then they're off and running. Is there any scope for adding a way in the client to connect to a broker from the GUI? Thanks, Iain Hallam.

x2go session failure because of unknown "localhost"
by flegoff 23 Jun '20

23 Jun '20

Hello list, I have been using x2go without issues for a long time until recently. Both client and server are running on Linux machines. I can connect to the server (via an SSH proxy). I get the "New session started" notification. But the session is apparently terminated because tere is some error resoling the display server. I copy pasted the log messages in the enclosed file. I think the important part is this: Loop: WARNING! Overriding auxiliary X11 port with new value '1'. Warning: Overriding auxiliary X11 port with new value '1'. Info: Using abstract X11 socket in kernel namespace for accessing DISPLAY=:0. Error: Failed to resolve address of 'localhost'. Loop: PANIC! Unknown remote host 'localhost'. Error: Unknown remote host 'localhost'. Session: Session terminated at 'Fri Jun 19 22:50:42 2020'. As far as I remember I haven't changed client or server configuration. I did switch from using Published App sessions to Xfce session to I have installed Xfce on the server. Published App sessions do not work either now. Any idea what is going on here? Or how to debug this? Cheers, Fabrice
