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.
