Has anyone figured out how to switch Houdini to fullscreen mode in GNOME 43+?

There's no difference between a maximized Houdini window and when it's switched to full screen. The program thinks that GNOME's top bar is still present, and while the titlebar is removed, the program window remains the same size as in maximized state.

Fedora 40 is wayland only (...)

I think Fedora will not remove X11 support anytime soon. The following article explains, that it's not that simple and there's still a division in the community and many issues with Wayland awaiting to be addressed, before it finally becomes a solid replacement for X11:

On Debian GNOME, Wayland is disabled by default when the OS detects NVIDIA proprietary drivers. Reportedly because Wayland currently doesn't cooperate well with NVIDIA. Or is it rather the other way around? XFCE doesn't support Wayland at all. It's planned for the future release. But while XFCE development moves steadily, it also moves slowly, so implementation won't happen anytime soon. KDE will still accept X11 contributions, as decided by KDE SIG.

The Fedora Engineering and Steering Committee (FESCo) agreed to reintroduce X11 support for Fedora 40.

So, for the time being, Xorg all the way, baby.

I've put some code in 20.0.699 to look for both libnvidia-ml.soand libnvidia-ml.so.1Please let me know if that sorts out all issues
thanks guys

Still working fine on Debian. No regressions. Hopefully it also resolves the issue on Fedora.
Thanks again for the fix, Brians.
