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.

x2go interferes with lyx
by Neal Becker 06 Aug '20

06 Aug '20

$ rpm -q x2goclient x2goclient-4.1.2.2-2.fc32.x86_64 I've noticed that if x2goclient is running that the UI for lyx running locally (NOT remotely) is very sluggish. Trying to operate menus, scroll windows, etc. are very sluggish. Kill x2goclient and the problem stops. lyx is a QT app. -- *Those who don't understand recursion are doomed to repeat it*
