Freshly installed openSUSE Leap doesn't show login screen under Windows 10 Hyper-V Creators Update

I’ve installed openSUSE Leap as a Hyper-V virtual machine under Windows 10 Creators Update.
After installation, VM arrives at boot screen but doesn’t show it, it remains black.
Switching to a textual terminal session, I can login.
I’ve tried rebuilding with both Leap stable and nightly DVDs. I’ve tried also rebuilding and selecting KDE instead of Gnome, same thing, ony KDE shows a ominous message about “The screen locker is broken… login and execute the command loginctl unlock-sessions…”

I’ve a log line, when using KDE, in journalctl that says “plymouthd of user 0 dumped core”

Any ideas?

How do you know it is login screen then?

This is a long standing bug on Leap 42.2 which is probably unrelated (it does not prevent normal GUI login at least).

Do you have /var/log/Xorg.0.log file? If yes, post it here or upload to http://susepaste.org/ if it is long. Also upload there output of “journalctl -b”.
