5:28 p.m.
I updated to F34 today and it all went very smoothly. I'm even running
KDE/Plasma under Wayland and so far haven't noticed any issues (touch
wood) ...
... except for this: according to:
https://fedoramagazine.org/whats-new-fedora-34-workstation/
" ... Fedora still defaults to X.Org when you install the NVIDIA
driver."
I have the proprietary Nvidia module loaded and both Xorg and Xwayland
are running, however there doesn't seem to be any access to the Nvidia
GPU. nvidia-settings reports:
"Unable to find display on any available system"
and my attempts to run Steam games using the Vulkan compatibility layer
(which runs happily on Xorg) don't work.
Just in case, I tried again using Gnome with the same result.
IOW, apparently Nvidia GPUs do not currently work with Wayland, but
don't work with Xorg either. Is there something I'm misunderstanding
here?

(Replying to myself).
On logging in with KDE/X11, nvidia-settings now works so at least the
GPU is accessible. Steam with Vulkan still doesn't but that may just be
a matter of waiting for a package update.
It's still true that Nvidia+Wayland is not working.

While I am running F33 at the moment I did a bit of testing of Plasma on Wayland
with nVidia drivers. Specifically, the 465.24.02 driver. And it works for me with
the limited amount of testing. I don't use nvidia-settings.
I get
DESKTOP_SESSION=/usr/share/wayland-sessions/plasmawayland
XDG_SESSION_TYPE=wayland
WAYLAND_DISPLAY=wayland-0
So, can you expound on "not working"?

On Plasma/Wayland I get those same settings, however the display is
running on the internal Intel GPU, not on the Nvidia. Even though the
Nvidia kernel modules are loaded, there appears to be no way to access
the GPU. Thus:
$ nvidia-settings
ERROR: Unable to find display on any available system
$ switcherooctl

Default: no
Environment: __GLX_VENDOR_LIBRARY_NAME=nvidia
__NV_PRIME_RENDER_OFFLOAD=1
$ switcherooctl -g 1 nvidia-settings
ERROR: Unable to find display on any available system
If I run Plasma/X11, all of the above works correctly (as it did on F33
of course). IOW, with Wayland the Nvidia GPU is currently useless.

I see.
Would it be fair to qualify the last statement by adding "in this use case"?
Is is possible to test this with the nvidia device being Default?
Is it possible to test with nouveau instead of nvidia drivers?

Would it be fair to qualify the last statement by adding "in this use
case"?
Only if someone can report an Nvidia GPU being used under Wayland. Note
that this is not a KDE/Plasma issue. I get the same results under
Gnome. Note that I'm using SDDM in all cases. I don't know if that
makes a difference though I don't see why it should.
Is is possible to test this with the nvidia device being Default?
I think that would mean blacklisting the IGP on boot, if that's even
possible. I don't know another way of selecting the default.
Is it possible to test with nouveau instead of nvidia drivers?
Probably. I'll look into it.

I'm currently using Plasma in Wayland with nVidia drivers. And I'm now running
handbrake to add subtitles in a movie using the H.264 (NVEnc) encoder which
is using the Nvidia GPU.
Does that qualify as "Nvidia GPU being used under Wayland"?

I'm currently using Plasma in Wayland with nVidia drivers. And I'm
now running
handbrake to add subtitles in a movie using the H.264 (NVEnc) encoder
which
is using the Nvidia GPU.
Does that qualify as "Nvidia GPU being used under Wayland"?
Certainly. I'd love to know why it's working for you and not for me. Am
I right in assuming you also have an internal GPU? If so, have you
configured anything to use the Nvidia as default? Are you running
Nouveau or the proprietary driver? What happens if you run nvidia-
settings or switcherooctl?

No, I only have a GeForce GTX 660. I'm running the nVidia drivers packaged by
rpmfusion. Neither nvidia-settings or switcherooctl work in wayland.

If you have no internal GPU then the Nvidia has to be the default, so
nvidia-settings mustn't be working for some other reason. Does it work
if you log in with X11?
Another question: is Xwayland running when you use Handbrake, or does
it run directly on Wayland?
More research needed.

nvidia-settings and switcherooctl fail when logged in Plasma Wayland. If I recall,
they say they can detect any device. I'd have to switch back to be certain.
Both work when logged in under X11.

I don't quite understand the question. I login Plasma Wayland and DESKTOP_SESSION
shows /usr/share/wayland-sessions/plasmawayland and then I start handbrake.

Slight correction :)
Switcherooctl works in Wayland in Fedora Workstation (Gnome).
KDE Plasma is lagging a bit.

Idem for a laptop with discrete (Nvidia) and integrated (Intel)

IIRC Xwayland is the shim that is supposed to allow X programs to run
under Wayland. When I run Plasma/Wayland I see it in my process list
(pgrep Xwayland). When I run Gnome/Wayland I don't.

That's what I don't get. Clearly you must be using the Nvidia GPU if
it's the only one you have, so why can't nvidia-settings find it,
especially as it does find it when under Gnome/Wayland?
Anyway, clearly Plasma/Wayland is not entirely trouble-free yet. Will
probably just have to wait.
