Hello!
sddm-kcm adds an “Apply Plasma Settings…” button to the KDE System Settings app. Pressing “Apply Plasma Settings…” allows you to synchronize your Plasma settings with SDDM.
I run NixOS, and I want to be able to add something to my NixOS configuration so that it automatically synchronizes my Plasma settings with SDDM without me having to manually go into System Settings and click on the “Apply Plasma Settings…” button. It would be nice if there was a command that I could run in order to synchronize my Plasma settings with SDDM. Then, I could make sure that that command gets run automatically as a part of my NixOS configuration.
Is there any way to synchronize my Plasma settings with SDDM from the command-line, or do I have to do it through the System Settings GUI?
