SUMMARY On linux plymouth is started during boot in-between grub2 and sddm. grub2 comes with a background, which could be changed by YAST, sddm can be customized by systemsettings5, which could change the background too. Only plymouth has no option. It seems to be nice and necessary, to have a backround/wallpaper ability too. The same background/wallpaper during all the steps of the boot process would be preferable. This is an example for this issue with an other distro: https://www.linuxliteos.com/forums/desktop-customization/background-image-when-starting-'the-feather'-4739/?PHPSESSID=a0lcqpabjrb2uuiuvb5utg7vo5 STEPS TO REPRODUCE 1. 2. 3.

That'd only make sense if people can actually set it via the KCM.
Created attachment 127001 [details] screenshot of systemsettings5/start and shutdown/startscreen In the left row there are two nearly identical startscreen items, only with different widgets, but without verbal explanation. There should be added: (plymouth), as it could be seen for sddm.
Addition to comment #2: /usr/share/kservices5/kcm_plymouth.desktop should have the same names mentioned in /usr/share/kpackage/kcms/kcm_plymouth/metadata.json. This would solve the issue in comment #2
Addition to comment #2: The German translation in kcm_plymouth.desktop "Name[de]=Startbildschirm" misses the item "Boot".
This might make sense on the basis of ending the profusion of splash screens on https://store.kde.org/browse?cat=488& that are just the default one with a different picture. That's low-effort content, but currently there's no real other way to get a splash screen with a different image on it. And yes, we'd also need a way to set it from the KCM.
The problem is more that each theme is free to use a different path. Supporting a wallpaper in breeze isn't really the problem there, it's all the other theme scripts - and that makes supporting it in the KCM a headache that needs a plan to deal with.
It, it would have to be a feature of the Breeze splash screen itself I guess, which we show a config UI for in the KCM.
Fine with me so long as we are ok with that limitation. That said, Walther, if you make an MR on invent.kde.org I'll gladly help get the changes landed :)
