What "reported surprise"? That sddm doesn't start?

Can you please provide /var/log/Xorg.0.log then?

Maybe you have to upgrade the nvidia driver to a newer version too.

As I wrote in another bug report, the latest version of the software "Simple
Desktop Display Manager" (with some additional fixes) should be in the next
Tumbleweed snapshot.
But that won't help if your OpenGL setup is broken.
