This might be it.
What’s the method to browse a repo for a specific version?
Linuxcapable.com suggests (over at https://linuxcapable.com/how-to-install-nvidia-drivers-on-fedora-linux/)
sudo dnf module list nvidia-driver
But I can’t seem to find nvidia-driver. Are these profiles it mentions unique to the nvidia-driver package, or is that a feature of rpm’s?
Yes, and thank you for your interest in helping. Appreciated! After an update, I will eventually reboot. When doing so, the options in the gear at the Gnome login will be

I haven’t been able to locate a log file where something looks relevant to the decision made at boot for XDG, Wayland, or X11 that chooses one over the other. It’s just as though Wayland stops being an option. 3 or 4 updates later, I’ll have Wayland back again - but no idea why it comes and goes. My caveman intuition tells me it happens around nvidia updates, but I haven’t kept strict notes on that.
