enable multiple login with the same user

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! Kanssoune ENGIE Mail Disclaimer: http://www.engie.com/disclaimer/

Hi! thank you for creating this nice free software! I tried x2go on Debian 10 server with KDE desktop. Everything worked fine out of the box until 3 days later when I noticed the server disk was full: in /home/dozent: -rw------- 1 dozent dozent 800G Mär 7 12:48 .xsession-x2go-bootserver-neu-errors [19069:19098:0307/002314.670828:ERROR:gl_surface_qt.cpp(296)] eglCreatePbufferSurface failed and surfaceless context not available [19069:19098:0307/002314.670831:ERROR:gl_surface_qt.cpp(303)] Requested OpenGL implementation is not supported.

Implementation: 0 I deleted the file and killed all processes of user "dozent" to free the disk space again. can you give me any advice how to avoid or limit those messages? Thank you!

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 get the following message from X2go client: NXPROXY - Version 3.5.99.20 Copyright (c) 2001, 2011 NoMachine (http://www.nomachine.com) Copyright (c) 2008-2014 Oleksandr Shneyder <o.shneyder(a)phoca-gmbh.de> Copyright (c) 2014-2016 Ulrich Sibiller <uli42(a)gmx.de> Copyright (c) 2014-2016 Mihai Moldovan <ionic(a)ionic.de> Copyright (c) 2011-2016 Mike Gabriel <mike.gabriel(a)das-netzwerkteam.de> Copyright (c) 2015-2016 Qindel Group (http://www.qindel.com) NXCOMP, NX protocol compression and NX extensions to this software are copyright of the aforementioned persons and companies.

I have a MacBookAir and that still connects to the same linux box fine via X2go client. I did get a message the other day on my iMac that I could update the version of Xquartz, which I did and continued to use X2go client successfully following this for a while and then X2go client then stopped working when I tried to connect one morning. 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

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.
