Plasma not using my login/lock screen settings

As the title says. Newest version of everything (beside AUR packages), following issue:
If I select a different lockscreen here:


And then apply plasma settings, type in root password, then hit aplly it switches back to default after typing in a root password the second time.
What’s going wrong here?

Lock screen doesn’t need to use root permissions. you are setting the login screen settings instead. Search for “locking” and you’ll find the lock screen configuration.

worked like a charm, thx! Buut:
I want to have both changed, so that does not solve my issue with the login screen :wink:

I see you’re still using the unsupported sddm. Try plasma-login-manager instead.

sudo pacman -Syu plasma-login-manager
sudo systemctl disable sddm
sudo systemctl enable plasmalogin

That did the trick, thanks again.
For anybody being as stupid as me:
The service is called plasmalogin, not plasma-login-manager

Updated. Thanks.

When I switched to Plasma Login Manager, I ran the same commands. I went the extrta step of sudo pacman -Rns sddm.
