it doesn't! even KDE has no love for screensavers. at most you can set the screen lock to be a picture slideshow.


OTOH if someone really wanted to make a screensaver that was just pretty graphics and no security, it would not be that hard. JWZ is only saying things like "I can't detect user activity on wayland" because he is a caveman and anything that's not down at the systems level doesn't exist to him. Kde has a way to get idle time and I'm sure gnome does too. So you could make a simple thing that waited until N idle minutes according to the window manager, then launched the fun demoscene screensaver.
