I want a display manager that shows the desktop as the background, instead of a background image or video. I'm thinking of auto-logging in on boot, and adding another startup command to Hyprland to lock the desktop and show the display manger. My searches didn't yield anything. The closest I could find is hyprlock which blurs the desktop, but that's just a lock screen & not a proper display manager.
what you are asking for doesn't really make sense.
a display manager is for running when no user is logged in. its purpose is to log in and start your session. thats why they can't show a desktop as a background because ot isn't running yet. once you log in the display manager quits because its job is done.
