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

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.

Re: [X2Go-User] Cross-session copy/paste issue
by Jonah Benton 24 Feb '21

Hi Uli, Thank you- concur about images- in the past, copy-paste of them only worked within a session, not across. My workaround was to paste-save to /tmp on the host and then open saved image from another session. But nearly all copy-paste for me is text / URLs. Re versions of nxagent: Currently: [admin@localhost ~]$ dnf list installed | grep nx nx-libs.x86_64 3.5.99.26-1.fc33 @updates nxagent.x86_64 3.5.99.26-1.fc33 @updates nxproxy.x86_64 3.5.99.26-1.fc33 @updates Previously version release schedule https://www.spinics.net/lists/fedora-package-announce/msg288622.html * Fri Jun 19 2020 Orion Poplawski <orion@xxxxxxxx> - 3.5.99.24-1 - Update to 3.5.99.24 * Sat Feb 1 2020 Orion Poplawski <orion@xxxxxxxx> - 3.5.99.23-1 - Update to 3.5.99.23 * Wed Jan 29 2020 Fedora Release Engineering <releng@xxxxxxxxxxxxxxxxx> - 3.5.99.22-2 - Rebuilt for https://fedoraproject.org/wiki/Fedora_32_Mass_Rebuild So I was previously running what Fedora calls 3.5.99.24. I can try to downgrade if there is an earlier 3.5.99 on Fedora 33- will that matter? Happy to give a go at a replacement build. I did just note two additional behaviors- 1. cross-session paste does *eventually* complete -copy of text 1 in session 1 -attempt to paste in session 2 -observe session 2 window freeze -switch to host window -paste into host window (success) -select and recopy in host window -switch back to session 2- paste of text 1 had completed So the paste took about 5 seconds 2. cross-session paste payload can be replaced in flight -copy of text 1 in session 1 -switch to session 2 -attempt to paste (text 1 into session 2) -observe session 2 window freeze -switch to another window in session 2 -select and copy text 2 (in another window in session 2) -switch to the session 2 window attempting to complete the original paste -note that the paste completed- but using text 2, not text 1 Thanks again!

X2GO Crash When Resizing columns in Cliosoft Sos
by Joe W 23 Feb '21

23 Feb '21

I am using a program called Cliosoft SOS. It has a window that displays in columns like an Excel file. When I resize one of the columns then my X2GO session window crashes. The start window where I pick which session to start stays running. There is a horizontal scroll bar to move the columns sideways. When I drag that then the X2GO window crashes. I can resize the entire SOS window without any problems. I do not see this sort of behavior in LibreOffice Calc. I have attached the session log and the client debug console output showing a few of these crashes. My client is v. 4.1.2.2 on Windows 10. I am connecting to a CENTOS 7 system running X2GO 4.1.0.3-9 server which came from the Epel repo. Is there some way to fix this or is it a bug that I should report? Is there any additional information that I should gather? Anything I should ask the software developer?

Cross-session copy/paste issue
by Jonah Benton 20 Feb '21

20 Feb '21

Hi folks, Let me first say thank you to X2Go maintainers- I happened upon X2Go about 6 months ago when figuring out how to switch my workflow from Fedora VMs on MacOS to distinct desktop environments on Fedora. It is such a profoundly excellent tool. Thank you for your efforts. Now- to describe a problem that just cropped up, hoping someone can help me debug. I have been running Fedora 32 - XFCE on a Thinkpad, simultaneously running 7 distinct local X2Go sessions under 7 different host users. Each session's window resides within its own XFCE logical desktop, and I switch between them with the switch desktop hotkeys. X2Go sessions are configured to support bidirectional copy/paste, and generally it works seamlessly to copy text or images from apps in one session's window to another or to/from the host. Last night I upgraded to Fedora 33, with the requisite updates to X2Go. Now, copy/paste is reliably broken in one area: * from host into any session still is fine * from session into host still is fine * from a session into the same session still is fine * from one session into another session no longer works On failed pastes- where the copy was from one session and the paste is another session- when the paste recipient is a browser (Chromium, Firefox, whatever), sometimes the recipient browser tab temporarily locks up trying (and failing) to retrieve the paste material. All X2Go sessions are still configured for bi-directional copy-paste. [admin@localhost ~]$ x2goclient --version x2go-WARNING-1> English language requested, not loading translator. x2go-WARNING-1> English language requested, not loading translator. 4.1.2.2 [admin@localhost ~]$ x2goversion : 3.2.0.0 : 4.1.0.3 : 4.1.0.3 : 3.2.0.0 : 4.1.0.3 : 3.5.99.26 : 4.1.0.3 Any thoughts on tracking down the issue? Thanks again, Jonah

session.log file fills disk

We are seeing this on multiple machines where the session.log file is massive. I've seen them as large as 82gb.

Shared folder fails silently on client side?
by James Bowery 20 Jan '21

20 Jan '21

For some reason the automounted shared folder is no longer being shared. Moreover, manually mounting doesn't work either. Yet there are no error messages in the X2Go CLient status window (Session ID:... Server:... Username:... Display:... Creation time (is blank?) and Status running). I'm not exactly sure where to look on the Ubuntu server for diagnostics, but it seems the client side should not be so silent under both automount and manual mount.

Single Application session fails
by Chris Green 18 Jan '21

18 Jan '21

I am running x2goclient on my laptop and the x2go server is on my dekstop, both systems are running xubuntu 20.10. Running an xfce session works perfectly but running a single application session doesn't. It appears to work until the application pops up momentarily and then disappears. The application *is* still running but is not displayed. The end of the session.log shows:- Info: keyboard blocking directory created: '/home/chris/.x2go/C-chris-50-1610816188_stRdigikam_> Info: Keycode conversion is off Session: Session started at 'Sat Jan 16 16:56:30 2021'. nxagentImportProperty: WARNING!
