Unable to Customize Login Screen (KDE)
Seems like no matter which route I take, the login screen refuses to change. I'm using Nvidia KDE image on a desktop.
Attempt 1 - System Settings -> Appearance & Style -> Login Screen (SDDM) -> Breeze Fedora, Change Background -> Load From File -> Select a new file -> Apply

Solution
I suspect that these instructions for Kinoite will work. https://www.reddit.com/r/Fedora/comments/12ywfst/kinoite_how_can_i_change_login_background/ but be careful when editing your /etc/fstab folder as you can end up with an unbootable system. I''m going to test them now
