I’m running Fedora 40 with kde plasma DE if it helps any
As the message is saying, you should try installing QtQuickControls
I have indeed tried that but it hasn’t worked.
Moral of the story. Don’t run Fedora 🥶
At a quick glance, the Sweet Amber Blue SDDM theme has two versions – one for Plasma 5 and another one for Plasma 6. You probably want the one for Plasma 6.
Thank you so much for the help. This was the fix for me. I had the plasma 5 theme and needed the plasma 6 one. Also the last tip about themes is very appreciated and will be considered. <3
You can also install wallpaper plugins from the KDE store for your lock screen background. I’m a fan of City Grow.
Have you tried reinstalling sddm and/or the theme? Had the same kind of error a few weeks ago were reinstalling did the trick for me
I’ve tried switching lock screen themes and gotten it to work temporarily but it goes back to default with that red error text on a reboot.
