[X2Go-Dev] Bug#1555: [Bug] X2Go: The remote NX proxy closed the connection
Package: x2goserver
Version: 4.1.0.3
When I run x2goclient 4.1.2.2, on my Windows 10 64-bit machine, the
following error appears:
*Error: The remote NX proxy closed the connection.*
*Error: Failure negotiating the session in stage '7'.Error: Wrong
version or invalid session authentication cookie*
The x2goserver 4.1.0.3 and nxagent 3.5.99.26 is installed on a RHEL 8.2
64-bits workstation.
On the RHEL 8.2 workstation, I tried to delete the x2go database and
recreate it without effect:
I also tried to run the x2goagent (see x2goagent.txt) thinking I got a
clearer error, but the x2go windows opened correctly.
I'm completely stuck and don't know what else to do. You will find attached
a maximum of log, hoping that this helps you to see more clearly.
Finally, I would like to point out that I can correctly connect to a second
workstation under RHEL 7.2 64-bits with x2goserver 4.0.1.20 and x2goagent
3.5.0.32.
Thank you.

[X2Go-Dev] Bug#1554: matlab colors inverted in X2go client
Package: x2goclient Version: 4.1.2.2 (Qt-4.8.7) When using Matlab on an Ubuntu linux server accessed through x2goclient, the Matlab window has inverted colors (e.g., background is black, text is various colors with different highlighted colors). I'm using x2go from a 2017 Macbook Pro with MacOS Catalina. I've recently found the matlab window inverts its colors when the x2goclient window is off-screen to the left, but when it's completely contained by my monitor window or slightly off-screen to the right, then the colors are normal. A similar problem happens on my colleague's 2020 Macbook Pro with MacOS Big Sur, but no matter how he configures the x2goclient window, his matlab screen still has inverted colors. ___ x2go-dev mailing list x2go-dev@lists.x2go.org https://lists.x2go.org/listinfo/x2go-dev
[X2Go-Dev] Bug#1553: x2goserver error: unknown operating system
Package: x2goserver Version: 4.1.0.4 When starting a x2go session with the server running Opensuse Tumbleweed OS I expect to get a session. What I get is the error message:|"Unknown operating system, XSession startup not implemented!" I looked at the x2goserver source code and it checked for ||[ -f /etc/SUSE-brand ] || [ -f /etc/SuSE-release ] which both are absent. I did a 'touch ||/etc/SuSE-release|' on the server and x2go started working again. So there should be a better detection for Opensuse Tumbleweed.

Hello, After the Virtualbox update from the version 5 to version 6 series: * Invoking copy/paste operations when shared clipboard is turned on causes the guest machine to immediately abort * Even with shared clipboard turned off in Virtualbox settings, guest machines generate an Abort status in Virtualbox during a normal shutdown * /var/log/messages indicates a segmentation fault in Virtualbox shclipboard application * These aborts do not occur when running Virtualbox over a ssh-X tunnel I'm wondering if this is related to the older nx-libs problem with shared clipboard submitted by mikedep333. x2go client: v 4.1.2.2 (Qt 5.15.2) running on Fedora 33 x2go server: : 4.1.0.3, nxproxy 3.5.99.26 John. ___ x2go-dev mailing list x2go-dev@lists.x2go.org https://lists.x2go.org/listinfo/x2go-dev

[X2Go-Dev] x2go client help
Hi, I am having an issue on a Mac Os 11.3 with the x2go client: The issue is that right after restarting my Computer I have no problem connecting to my remote server. But after I stop that session and restarting it later I get the eternal “connecting" status. The only way to fix this is by restarting my computer. My guess is I have to kill some process, but it is not obvious to me which one. Could you help me troubleshoot this?

Package: x2goserver Version: 4.1.0.3 I'm packaging x2goclient and x2goserver for voidlinux distro. Voidlinux doesn't use systemd as init, but runit. We need to be able to write a runit service script for x2gocleansessions. x2gocleansessions forks when it is run. Using --debug doesn't fork but print a lot of informations, catched by the service. Could you separate --no-fork from --debug please ?

[X2Go-Dev] Pull request: add --nofork option to x2gocleansessions
Greetings,
Following is a pull request against the 4.1.0.x branch that separates
the no-fork behavior of x2gocleansessions from the debug output
behavior. A new flag, `--nofork` (`-n-` for short) determined whether
the program forks; `--debug` only controls the logging verbosity and
also forces `$nofork=1` to preserve old behavior.
Please let me know if anything should be changed.
Thanks,
Andrew Hesford
