What about disabling AppArmor temporarily? From your log it seems the ssh connections are working, they are just closed preliminary. This usually happens when the last client of x2goagent/nxagent exits. Which in turn might point to something (like AppArmor/SELinux stopping xterm from running at all).

Yes, I've tried launching other single applications as well (xfce4-terminal, konsole, etc.), as well as entire desktops (such as IceWM) and get the same results. Running applications remotely via ssh -X works fine. Over the past year or so openSUSE has been gradually "hardening" their distributions (via stricter AppArmor profiles, etc.). I've had several important applications break as a result. Usually it's obvious that this hardening is the cause, and a bug report to openSUSE usually ends up with them either reversing the hardening, or else explaining why the hardening is an appropriate default and then suggesting a workaround. But in this case it's not clear to me that this hardening is the cause of the problem. My latest system update did pull in some updates to openssh but not to x2go (since I use packages I've compiled and packaged myself). Maybe I should see if it's possible for me to roll back the openssh changes and see if that works around the problem.

Results of some further testing: * The problem seems to happen only when connecting to the server running on openSUSE Tumbleweed. Connecting to a server running on another machine (running openSUSE Leap 15.3) still works. * The problem doesn't seem to have anything to do with the particular account I'm connecting to. I still get the automatic disconnect when logging in as a different user. * Here are the server logs with logging level set to "info": 2022-05-31T10:39:56.310889+02:00 butterfield sshd[12197]: Accepted publickey for psy from 193.171.142.173 port 44850 ssh2: RSA SHA256:GlTL06/Ur8aKEq01wDiI9ghRdgSkXfkDVDsx4qiKNms 2022-05-31T10:39:56.830523+02:00 butterfield /usr/bin/x2gostartagent: x2gostartagent called with options: 800x600 adsl 16m-jpeg-1 unix-kde-depth_24 us auto 1 R xterm both 2022-05-31T10:39:57.019028+02:00 butterfield /usr/bin/x2gosessionlimit[12372]: x2gosessionlimit has been called 2022-05-31T10:39:57.078710+02:00 butterfield /usr/bin/x2golistsessions[12373]: x2golistsessions has been called with options: --all-servers 2022-05-31T10:40:08.013742+02:00 butterfield /usr/bin/x2gofeature: x2gofeature called with options: X2GO_RUN_EXTENSIONS 2022-05-31T10:40:08.039863+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver-extensions.features: x2goserver-extensions.features called with options: X2GO_RUN_EXTENSIONS 2022-05-31T10:40:08.066317+02:00 butterfield /usr/bin/x2goserver-run-extensions: x2goserver-run-extensions called with options: psy-1539-1653986406_stRxterm_dp24 pre-start 2022-05-31T10:40:08.111792+02:00 butterfield /usr/bin/x2gostartagent: creating new session: psy-1539-1653986406_stRxterm_dp24 75ac6c60151cfea222f2e9f184f1643b 13277 193.171.142.173 49517 49518 49519 -1 -1 2022-05-31T10:40:08.257567+02:00 butterfield /usr/bin/x2gostartagent: successfully started X2Go Agent session with ID psy-1539-1653986406_stRxterm_dp24 2022-05-31T10:40:08.289281+02:00 butterfield /usr/bin/x2gofeature: x2gofeature called with options: X2GO_RUN_EXTENSIONS 2022-05-31T10:40:08.315905+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver-extensions.features: x2goserver-extensions.features called with options: X2GO_RUN_EXTENSIONS 2022-05-31T10:40:08.342553+02:00 butterfield /usr/bin/x2goserver-run-extensions: x2goserver-run-extensions called with options: psy-1539-1653986406_stRxterm_dp24 post-start 2022-05-31T10:40:08.678631+02:00 butterfield /usr/bin/x2goruncommand: x2goruncommand called with options: 1539 13277 psy-1539-1653986406_stRxterm_dp24 49518 /usr/bin/xterm nosnd R 2022-05-31T10:40:08.713913+02:00 butterfield /usr/bin/x2gofeature: x2gofeature called with options: X2GOAGENT_RANDRXINERAMA 2022-05-31T10:40:08.742595+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver-extensions.features: x2goserver-extensions.features called with options: X2GOAGENT_RANDRXINERAMA 2022-05-31T10:40:08.769154+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver.features: x2goserver.features called with options: X2GOAGENT_RANDRXINERAMA 2022-05-31T10:40:08.796058+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver-x2goagent.features: x2goserver-x2goagent.features called with options: X2GOAGENT_RANDRXINERAMA 2022-05-31T10:40:08.829722+02:00 butterfield /usr/bin/x2gofeature: x2gofeature called with options: X2GO_RUN_EXTENSIONS 2022-05-31T10:40:08.856138+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver-extensions.features: x2goserver-extensions.features called with options: X2GO_RUN_EXTENSIONS 2022-05-31T10:40:08.882619+02:00 butterfield /usr/bin/x2goserver-run-extensions: x2goserver-run-extensions called with options: psy-1539-1653986406_stRxterm_dp24 pre-runcommand 2022-05-31T10:40:08.930031+02:00 butterfield /usr/bin/x2gosetkeyboard: x2gosetkeyboard called with options: 2022-05-31T10:40:08.934918+02:00 butterfield /usr/bin/x2gofeature: x2gofeature called with options: X2GO_XSESSION 2022-05-31T10:40:08.950084+02:00 butterfield /usr/bin/x2gosetkeyboard: Waiting for /home/psy/.x2go/C-psy-1539-1653986406_stRxterm_dp24/keyboard to appear 2022-05-31T10:40:08.961226+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver-extensions.features: x2goserver-extensions.features called with options: X2GO_XSESSION 2022-05-31T10:40:08.988212+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver.features: x2goserver.features called with options: X2GO_XSESSION 2022-05-31T10:40:09.015186+02:00 butterfield /usr/share/x2go/x2gofeature.d/x2goserver-x2goagent.features:
