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. … [View More]

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 … [View More]

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 … [View More]

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 … [View More]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 [View Less]
