Blank Screen (no login screen) after latest Leap 42.1 online update

I am running Leap 42.1. After the latest online update, which upgraded my kernel from 4.1.12 to 4.1.13, when the boot process is finished there is NO login screen - just a blank (black) screen. I normally log in with KDE Plasma.

I can still switch to a text-based console login (via CTRL-ALT-F2) - but have no X.

I use the NVIDIA repository, and I can see that (after the online update) the NVIDIA driver IS loaded, so I’m not sure that’s the problem…

I downgraded my version of sddm from 0.13.0-7.3 to 0.12.0-5.1 and now it works.

Not ideal…

Did you ever get a response to your question or find a solution?. I ran into the same issue and can’t figure out how to fix it?

Any help would be appreciated.
