Way to stay on Nvidia 550 w/ Fedora 40? (lemmy.today)

Been running Fedora 40 for a few months, and having a hard time keeping Wayland as the desktop environment. Just did a fresh install, and the Nvidia driver updates to 555.58.02. I really want to stick with the Recommended branch, not the New Feature branch. Every update, Wayland breaks. How do I rollback to 550, and switch to the Recommended Branch for updates?

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

  • Gnome
  • Gnome Classic

Both of these options are X11. I verify this with $ echo $XDG_SESSION_TYPE and see X11. When Wayland is working, the Gnome login will show four session types:

  • Gnome
  • Gnome Classic
  • Gnome on X.org
  • Gnome Classic on X.org

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.
