[X2Go-User] session freezing

Client and server are both Fedora 35.

xfce session.

This setup has worked for years. An SSD failed on the server, and after re-installing F35 on it, now x2go session keeps freezing. Seems to happen at least when it is left running unattended. The x2go screen is shown, but unable to get focus into any window, click on any icon. Suspend/unsuspend does not fix it. Only terminate and restart fixes it.

Any suggestions?

Thanks, Neal
