I’ve attached a literal screen shot of all systemd errors. It seems to be caused by kscreenlocker_greet because of a missing shared object file. The boot 9 hours ago was from a read-only snapshot, and therefore doesn’t have it.
I have already tried updating with zypper dup, but that did not help.

package, which contains the missing library
