Big problem with keyboard/layout
by webman＠manfbraun.de 05 Sep '21

05 Sep '21

Hello! I hope, I can find some help here. I started once setting up x2goserver in a LXC container on a remote host and this, in some way, worked so far (except for using webbrowsers, which have only horrible performance and no sound) and even consoles have the right layout. Then I could not find an ytime to continue. Now, I setup x2goserver on thre computers, means, direcly like usually on the hardware (x2go: 4.1.0.3-4). All my boxes running debian10, kernel 5.10 running xfce, english setup, using a german keyboard layout. Shockingly, the keyboards are all wrong and unusable, there is, most prominent, no pipe character (and others are missed too, like the navigations keys, <alt-gr>, <del> but umlauts are correkt!). If you press <alt-gr> a beep ist issued. This happens to x-consoles as gui progs! XRDP, on the other hand, worked as before. I was unable to find documentation, which points out how this all works, how keyboard/maps are done by default on client and server, how this is initialized or how this could be changed and on which side (or a full shortcut reference). I tried to modify the settings on the client-gui (4.1.2.2 ) session configuration, but no variant (like "de-de") has influence at all. Thanks any way, Manfred

x2go client using 16% cpu when not connected
by Jason Palmer 17 Aug '21

17 Aug '21

Hi, I noticed that x2go client uses 16% cpu and "high power" when run, even before connecting. When closed, cpu usage stops. This is on Alienware M13 R1, Windows 10. Weirdly the cpu usage shows under the "System" process in task manager. I have run sysinternals from Microsoft, and checked thread addresses that are active under the System processes. The processes are just kernel processes. And weirdly, System only shows as using 8% cpu in sysinternals, but 16% in task manager. Microsoft process monitoring is obviously lacking, unsurprisingly. Anyone else experience this, or have an idea what is going on? No viruses are reported. My hunch based on using this laptop is that the graphics card driver is running some system process when x2go is run, but the whole thing is very mysterious and confusing. Thanks, Jason

Error binding localhost
by richard lucassen 14 Aug '21

14 Aug '21

I work with x2go for many weeks and regularly put the session in "pause". This normally works well, but sometimes (randomly) I get, when resuming: Unable to create SSH tunnel for X2Go session (NX) startup: Error binding localhost:<port> I cannot find anything about this issue in .xsession-x2go-x2go-errors. There is nothing listening on localhost:<port> as reported and IIRC a new session after a reboot starts with display :50 but apparently it has changed to :51 What can I do to debug this? For the moment I reboot the box (lazy) as all processes are still running. R. -- richard lucassen http://contact.xaq.nl/

connecting to a just booted machine
by Carlos Alfaro 08 Aug '21

08 Aug '21

Hello and thanks in advance to those who take the time to respond. I tried this before and it doesn't work. I have my x2go client machine and my x2go server. The server ( I have tried POP_Os, Ubuntu, LXLE and Lubuntu) and I am able to install it properly. My problem is that from the client side, I use my firewall to send a WOL pocket to turn on some of the machines which do not stay on 24/7. The ones that are always on I just launch the session and I am in. When I wake up a machine or reboots because of a power outage, I can use a terminal and log on to the machines via ssh. I open the ssh port on the firewall and I can log on just fine. This is the problem, while I can log on to the machine via SSH I can't connect with the x2go client right after the machine boots up. I have to manually walk to the machine and log on by entering my user name and password and then I can connect with the x2go client. This is not a problem in my local lab but it is a problem for the remote machines where there isn't always someone there to log on to the machine so I can then log on using the x2go client. Once logged in, no problem, I can lock the machine, put it to sleep, wake it again with WOL and log on with the x2go client again and again. Any suggestions as to where I can look at or what configuration setting to add or change so I can launch as session and get the log on screen of the server? Thanks again Charlie

Browsers (Firefox, chrome) stopped working in x2go sessions in CentOS7
by Grigory Shamov 04 Aug '21

04 Aug '21

Hi All, We had a problem , for a while now, that browsers do not work under x2go in our CentOS 7 servers. I think it started somewhere in Cent 7.6 and definitely stays on now in CentOS 7.9. The browser starts , but cannot create any child processes. So, no tabs, windows, or pages ever gets opened. Has anyone met this issue? What would be a way to troubleshoot it? Thank you very much in advance! -- Grigory Shamov WestGrid Site Lead / HPC Specialist University of Manitoba

Session not starting with Python 3 on Windows
by Tomáš Cerha 02 Aug '21

02 Aug '21

Dear list, I am using the X2Go Python API to develop a custom UI for running our applications from Windows and Linux client machines. We are now migrating to Python 3. The client now works on Linux in Python 2 and 3 and on Windows in Python 2. I, however, can’t get it to work in Python 3 on Windows. I see that the official PyHoca GUI for Windows is still Python 2.7 so I am curious what is the current state of X2Go migration to Python 3 and whether there are some known issues. Some details of my particular problem: I am trying to start xterm (for testing) from Windows on a Linux server. My client starts the X2Go session, starts nxproxy, but the xterm window doesn’t appear. The client’s log looks like this: pytis2go[8736] (x2goclient-pylib) DEBUG: command for new session is: xterm pytis2go[8736] (x2gocontrolsession-pylib) DEBUG: executing command on X2Go server ,,xterm Python 3'': echo X2GODATABEGIN:dfa49ff9-eec5-11eb-80a1-080027e6e559; PATH=/usr/local/bin:/usr/bin:/bin sh -c "echo"; echo X2GODATAEND:dfa49ff9-eec5-11eb-80a1-080027e6e559 pytis2go[8736] (x2goguardian-pylib) DEBUG: Entering X2Go Guardian client management loop... pytis2go[8736] (x2goproxy-pylib) DEBUG: NX3 Proxy mode is server, cookie=2532ea9e54c10c087472bb500e715d1d, host=127.0.0.1, port=52113. pytis2go[8736] (x2goproxy-pylib) DEBUG: NX3 proxy writes session log to C:\Users\IEUser\.x2go\S-cerha-50-1627381881_stRxterm_dp32\session.log. pytis2go[8736] (x2goproxy-pylib) DEBUG: forking threaded subprocess: C:\pytis2go\win_apps\nxproxy\nxproxy.exe -S nx/nx,options=\..\S-cerha-50-1627381881_stRxterm_dp32\options:50 pytis2go[8736] (x2goproxy-pylib) DEBUG: waiting for proxy to come up: 0.4s x 1 pytis2go[8736] (x2goproxy-pylib) DEBUG: waiting for port fw tunnel to come up: 0.5s x 1 pytis2go[8736] (x2goguardian-pylib) DEBUG: Entering X2Go Guardian client management loop...

Does anyone have any idea how to proceed? What to check or how to further debug it? Thank you for any idea. Best regards Tomáš Cerha

Speedup Desktop Performance
by res1＠embeddedjava.de 27 Jul '21

27 Jul '21

Hi everyone, I noticed that the desktop performance is relatively slow, especially also for direct connection to the local PC (X2Go-Client on Local machine connects to X2Go-Server on Local machine). My expectation is that such connection (possible only over the loopback device) should run very fast, but isn't. So why is this the case? The same issue I observed in the local network (at 1GBit speed). That means that connections over the global net can't be fast, if it is not possible with direct connections or local net, if there are some speed issues than the remote desktop is not usable anymore. I don't think that my PC is the bottleneck (Ryzen 3700 + 32GB RAM + PCIe SSD). Regards, Thomas

Connect to local desktop with larger resolution
by Darko K. 15 Jul '21

15 Jul '21

Hi, I am connecting to my remote machine using X2Go. So far everything works fine but I can't figure out one detail. Namely the remote PC has two monitors attached with resolutions 1920x1200 and 1600x1200. This results in desktop resolution 3520x1200. My local desktop resolution is 2560x1440. Both PCs are running Linux. I have created a new session in X2Go Client with type set to 'Connect to local desktop'. No matter what resolution I set in session preferences, client creates a window with size 1921x1200. The contents of the remote desktop is scaled down to fit into that window. This is pretty much unusable since the remote desktop's resolution is so big. I expected it to create window with scroll bars and no scaling. Enabling or disabling Xinerama extension in session preferences does not help either. With it enabled I see content of both monitors, with it disabled I see content of one monitor with the remaining part of the remote desktop being blacked out. I checked all command line options and I could not find anything that would hint at solving my issue. Thanks for your help, Darko

nxagent SIGSEGV when running glxinfo (and firefox) on a host with cuda installed
by Norman Gaywood 14 Jul '21

14 Jul '21

We have some centos 7 systems with GPUs that users access with x2go to run their machine learning task. After an update to cuda on the centos 7 systems, nxagent now segfaults when I run glxinfo or firefox. nxagent-3.5.99.26-1.el7.x86_64 x2goserver-4.1.0.3-9.el7.x86_64 cuda-11.4.0-1.x86_64 kmod-nvidia-latest-dkms-470.42.01-1.el7.x86_64 What's also interesting is that if I x2go into a host that does not have cuda installed, and then: ssh -Y cudahost glxinfo then the nxagent on the non-cuda host segfaults. This happens with glxinfo and when trying to start firefox. google-chrome works fine. This was all working fine until I updated cuda and the GPU driver. On Centos 7.9.2009 This happens on a host with a K80 GPU and another host that has a V100 GPU. I also have cuda-11.4 on a Fedora 34 host with a V100 GPU. If I x2go (or ssh -Y) to the Fedora 34 host, glxinfo (and firefox) run fine. nxagent-3.5.99.26-1.fc34.x86_64 x2goserver-4.1.0.3-10.fc34.x86_64 cuda-11.4.0-1.x86_64 kmod-nvidia-latest-dkms-3:465.19.01-1.fc33.x86_64 Any suggestions on how I might provide some debugging information to the developers? abrt-cli list --since 1626070479 id 35db2c461122be7229abdbe219ddfd92d0613da8 reason: nxagent killed by SIGSEGV time: Mon 05 Jul 2021 09:37:02 AEST cmdline: x2goagent -nolisten tcp -nolisten tcp -dpi 97 -D -auth /home/ngaywood/.Xauthority -geometry 2560x1440 -name X2GO-ngaywood-50-1625441817_stDMATE_dp24 :50 package: nxagent-3.5.99.26-1.el7 uid: 5125 (ngaywood) count: 21 Directory: /var/spool/abrt/ccpp-2021-07-05-09:37:02-2523 -- Norman Gaywood, Computer Systems Officer School of Science and Technology University of New England Armidale NSW 2351, Australia ngaywood(a)une.edu.au http://turing.une.edu.au/~ngaywood Phone: +61 (0)2 6773 2412 Mobile: +61 (0)4 7862 0062 Please avoid sending me Word or Power Point attachments.

x2go session resume always fails (long post)
by Norm Green 05 Jul '21

05 Jul '21

I'm having a problem resuming x2go sessions which now fails 100% of the time. The only way to use x2go is to kill all x2go processes on the server and restart x2goserver service, which causes the suspended session to be lost. This is driving me crazy. Any hints on how to debug this? Client is x2go 4.1.2.2 on windows 10 server is x2go 4.1.0.4-0 on Unbuntu 18.04 At the point the session is suspended, everything looks normal: I have a session and the x2goagent is still running. normg@moop>x2golistsessions 26617|normg-50-1625002538_stDXFCE_dp32|50|moop|S|2021-06-29T14:35:39|6fa8d13074afab1c2d58dee02b1085d8|10.94.155.18|43587|43588|2021-06-29T14:50:02|normg|1016|43589|-1|-1 normg@moop>cat state SUSPENDED normg@moop>cat options nx/nx,link=adsl,pack=16m-jpeg-9,limit=0,root=/tmp/.x2go-normg/C-normg-50-1625002538_stDXFCE_dp32,cache=8M,images=32M,type=unix-kde-depth_32,id=normg-50-1625002538_stDXFCE_dp32,cookie=6fa8d13074afab1c2d58dee02b1085d8,errors=/tmp/.x2go-normg/C-normg-50-1625002538_stDXFCE_dp32/session.log_errors,kbtype=null/null,geometry=800x600,xinerama=0,resize=1,fullscreen=0,accept=localhost,listen=43587,clipboard=both,client=linux,menu=0,state=/tmp/.x2go-normg/C-normg-50-1625002538_stDXFCE_dp32/state:50 normg@moop>tail session.log autograb : Ctrl+Alt+g dump_clipboard : Ctrl+Shift+Alt+c Info: keyboard blocking directory created: '/home/normg/.x2go/C-normg-50-1625002538_stDXFCE_dp32/keyboard' Info: Keycode conversion is off Session: Session started at 'Tue Jun 29 14:35:50 2021'.

Zoom Desktop Client will not start over X2Go
by Justin Paulsen 02 Jul '21

02 Jul '21

Hello, When I connect over X20go to my Debian 10.9 workstation and try to start the Zoom Desktop Client it crashes immediately without even showing up. If I start it on the workstation locally it starts without issue. Has anyone else run into this issue, and if so have you found a solution? Use case: Sharing a window on the remote system during a meeting. Sharing the entire x20go session window is not desirable. Thank you!

I run x2go server (custom: /usr/bin/wmaker). When starting WindowMaker I run: xset b off which should switch off the bell. But quite often the bell still works, even after logging out and in. Anyone a hint? R. -- richard lucassen http://contact.xaq.nl/

Windows UAC Prompts
by Tobias Botens 28 Jun '21

28 Jun '21

Hey, during the installation of x2go on Windows 10 we are getting Windows UAC-Prompts. We want to distribute the Software via our Software-Distribution Product. How can we achieve a "silent Installation" without these prompts. If needed, we will create the firewall-Rules manually in our deployment-process. Kind Regards Tobias Botens
