Re: Session x11 not working. Any action on desktop is ignored.
I've been having what sounds like similar problems, but with both X11 and Wayland. Restarting X (when using X11) via SSH seems to result in the system locking up again almost immediately. Mine's running in KVM, and I had wondered if that was making any difference.
BACKUPS are unsexy — until you discover you should have done one yesterday.
Spare your nerves and do one before you upgrade or install.
