If you wish to play with login and lock screen stuff, go to Main Login /usr/share/sddm/themes/your-login-theme/main.qml Lock Screen Login Helps to know that breeze is the default Plasma lock screen theme. If a lock screen is not part of whatever theme you are using, then Plasma will use the breeze one. /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/lockscreen/LockScreenUi.qml In both of those files you will find something like this (I have added the corrections): WallpaperFader { // visible: false keeps from fading the wallpaper visible: false // Commenting out "anchors.fill: parent" will also do it. //anchors.fill: parent state: lockScreenRoot.uiVisible ? "on" : "off" source: wallpaper mainStack: mainStack footer: footer clock: clock } Either one of those corrections will do the trick. I don't like blurred backgrounds on my login screens. They particularly look bad if they are already dark pictures. Anyway, good luck.
