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.
Youre looking for a lockscreen. like people have suggested, id say the sweetest way is writing your own simple script. For example, take a look at my lockscreen script to get a feeling of things.
your can take a screenshot of the screen and blur it and set it as background each time.
