Have you tried with something else but xterm? Does xterm work when starting it via ssh -X?

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.

Re: [X2Go-User] x2go immediately disconnects after connection
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).

Hmm, next would be you suggestions to downgrade ssh (and/or check what has changed between the old and the new version.
