That gets you a working driver but not OpenGL or any of the core Nvidia
driver utils/libs such as nvidia-smi, nvidia-settings, nvidia-xconfig,
etc. If you try to install Steam for example it will blow up real bad.
If you
install steam from flatpak, we cannot know which tools are
needed on the "host" side, so this become a documentation issue.
The "no OpenGL driver" is a situation that cannot arise with the
nvidia packaged driver because we rely default to install it. So it's
more probably a delay between the availability of the nvidia-gl
overlay ?
I'm not sure to understand what you mean here. Unless you mean the
OpenGL.so over the "legacy" libGL.so ?

If memory serves me correctly nvidia-settings *is* silently installed
but not explicitly. In other words, you can see and launch the
application in Gnome 3 without explicitly installing it but doing:
rpm-ostree install nvidia-settings
Will still work and "install" the package despite it already been
installed. I'll have to do another reinstall and install just the driver
to make sure. Could be smoking shrooms here but I remember it being there...
I'd like to pose the question though, is this really a good thing?
People don't like it when you silently install things behind their back.
A meta package(at least in the form I'm thinking of) is different as it
points to other packages and says to install those packages. If you want
more information on what those packages contain you should be able to
lookup what each package provides.
A meta package is yet-another-package that do
not provide any content.
It's totally spurious in Fedora packaging land. (over boolean deps,
virtual provides, etc).
The other point is that usually, you should enable the nvidia driver
from the "software" application. On regular fedora the
rpmfusion-nonfree-nvidia-driver is selectable from the interface
(don't know about silverblue, but it was intended).
You just have to install the driver by selecting it, so you don't even
have to worry about the gory details of the packaging name.

the 32-bit libraries or not. Really, meta packages would go a long way in simplifying GPU
driver installs!

That doesn't work for 32-bit games though since they don't use the
package manager and Steam does need 32-bit libs if not installed via
Flatpak. Yes, Steam provides many 32-bit libs but as they have said
during the whole Ubuntu 32-bit support mess, they still use system libs.
Which libs? I don't know, they'd probably have a good idea.
Theses libs are
know as soon as the support
It isn't possible to play Proton games using Fedora Steam but is
possible with Flatpak Steam for example which I can only assume is
because of missing 32-bit libs. Installing Wine would probably pull in
the requires 32-bit libs since Proton is Wine...
No, this is wrong, I have proton
support in regular Fedora. with the
steam package from RPM Fusion.
>> Neither Windows nor even other Linux distros fragment the
driver this much. You'd have to add 32-bit libraries alongside the 64 bit driver and
64 bit libraries to equal Fedora's fragmented driver packaging in some distros. Why?

I've never heard of a situation where you would *just* want the driver
and *not* (at the very least) OpenGL support. Are there any examples?
Can CUDA be used without OpenGL?
Yes, only few cuda functions requires OpenGL

But the above site is not affiliated to either fedora or rpmfusion and
might provide a totally in-accuratte information.
rpm-ostree install akmod-nvidia xorg-x11-drv-nvidia = core working
driver
Nope, It's the default interface to install the driver not the
"Core" one.
rpm-ostree install xorg-x11-drv-nvidia-libs = OpenGL/Vulkan
False, it's a dependency of the xorg-x11-drv-nvidia, this is the usual
multilibs split, so it's very much a trivial packaging meme.
rpm-ostree install nvidia-settings = explicitly installed
nvidia-settings
Wrong, it's mandatory for any desktop usage so far it cannot be
bypassed.
rpm-ostree install nvidia-xconfig = x config utility for Nvidia
Wrong, it's a deprecated tool only needed for sample, it shouldn't be
used on fedora (or even documented, sorry but too much bad history on
this tool).
rpm-ostree install xorg-x11-drv-nvidia-cuda
xorg-x11-drv-nvidia-cuda-libs = nvidia-smi
Wrong, xorg-x11-drv-nvidia-cuda will
requires
xorg-x11-drv-nvidia-cuda-libs, (same packaging meme as above).
As I said I can evaluate a RFE to move the nvidia-smi to the default
set of packages, maybe enforce the -cuda to be installed by default
(with recommends).
But let's move to bugzilla.
Thx for the report.
