This isn’t a constructive answer Leigh. Let’s please keep to helping the user with their specific query—negative remarks about tools are not useful, and we’re not being excellent to everyone here.
I’ve seen my display do a similar spam of display connects on i915 Intel a while back, but I’m not sure on specifics (might have been modesetting vs intel DDX or color/icc/GNOME’s color daemon).
I’d try using open NVIDIA GSP; I recall that doing something different with my display in logs vs regular proprietary drivers.
If you do a reinstall, I’d check logs frequently while setting up and up to NVIDIA’s driver install to see if it starts happening out of nowhere; you might be able to narrow it down to a setting or package install/update.
I went looking to see if others had similar issues, and found this:
It does provide a workaround/fix but they’re not using journalctl from the looks of it. Perhaps the documentation will have some hints. I’m not running X11 here on this machine, unfortunately, so I can’t quite check how gdm-x-session calls X on my machine either, but perhaps there’s a way to tweak that on Fedora. It’ll require some digging.
