Installed today’s Rawhide ISO on my laptop and attempted to install the NVIDIA driver:

sudo dnf config-manager addrepo --from-repofile=http://dl.fedoraproject.org/pub/alt/rawhide-kernel-nodebug/fedora-rawhide-kernel-nodebug.repo


sudo dnf install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

sudo dnf config-manager setopt fedora-cisco-openh264.enabled=1

$ sudo dnf update --refresh

sudo dnf install "kernel-devel-uname-r >= $(uname -r)"

sudo dnf copr enable kwizart/nvidia-driver-rawhide -y

Then a reboot. I have these repos active now:

$ dnf repolist --enabled

Thanks, a higher version is already being used and it doesn’t work, I just edited my post :slight_smile:

That is a standard rawhide kernel, it has debugging enabled so prevents the closed driver from building.
The nodebug kernel versions are

$ rpm -q kernel |grep fc43
kernel-6.15.0-0.rc2.22.fc43.x86_64
kernel-6.15.0-0.rc4.35.fc43.x86_64
6

Right! I just don’t know why it’s not being used:

$ sudo nano /etc/yum.repos.d/fedora-rawhide-kernel-nodebug.repo

[fedora-rawhide-nodebug]
name=Rawhide Nodebug
baseurl=https://dl.fedoraproject.org/pub/alt/rawhide-kernel-nodebug/$basearch/
skip_if_unavailable=True
gpgcheck=0
repo_gpgcheck=0
enabled=1

Already tried to sync all kernel packages to the nodebug stream:

sudo dnf --enablerepo=fedora-rawhide-nodebug \
     distro-sync --allowerasing kernel\*

Remove any leftover debug kernels:

sudo dnf remove 'kernel-6.15.0-0.rc4.20250502*'

sudo dracut --force
sudo grub2-mkconfig -o /boot/grub2/grub.cfg

sudo reboot

$ uname -r
6.15.0-0.rc4.20250502gitebd297a2affa.39.fc43.x86_64
7

What I also tried was to explicitly install:

sudo dnf install --repo=fedora-rawhide-nodebug   kernel-6.15.0-0.rc4.35.fc43.x86_64   kernel-core-6.15.0-0.rc4.35.fc43.x86_64   kernel-modules-6.15.0-0.rc4.35.fc43.x86_64   kernel-modules-extra-6.15.0-0.rc4.35.fc43.x86_64

removed the other ones, so now I have:

$ rpm -qa 'kernel*' | sort
kernel-6.15.0-0.rc4.35.fc43.x86_64
kernel-core-6.15.0-0.rc4.35.fc43.x86_64

kernel-modules-extra-6.15.0-0.rc4.35.fc43.x86_64

even exluded the std. kernel in fedora-rawhide.repo

$ sudo nano /etc/yum.repos.d/fedora-rawhide.repo

The kernel devs have made that symbol gpl only.

Upstream nvidia will have to address this issue in the closed source driver.
It compiles here ok as I’m using the nvidia open source module.

There is a dirty fix which involves changing the module licence to GPL

[leigh@mpd-pc kernel master]$ grep MODULE_LICENSE -r
nvidia-uvm/uvm.c:MODULE_LICENSE("Dual MIT/GPL");
nvidia-modeset/nvidia-modeset-linux.c:  MODULE_LICENSE("NVIDIA");
nvidia-peermem/nvidia-peermem.c:MODULE_LICENSE("Linux-OpenIB");
nvidia/nv.c:MODULE_LICENSE("NVIDIA");
nvidia-drm/nvidia-drm-linux.c:  MODULE_LICENSE("MIT");

to match kernel-open

[leigh@mpd-pc kernel-open master]$ grep MODULE_LICENSE -r
nvidia-uvm/uvm.c:MODULE_LICENSE("Dual MIT/GPL");
nvidia-modeset/nvidia-modeset-linux.c:  MODULE_LICENSE("Dual MIT/GPL");
nvidia-peermem/nvidia-peermem.c:MODULE_LICENSE("Dual BSD/GPL");
nvidia/nv.c:MODULE_LICENSE("Dual MIT/GPL");
nvidia-drm/nvidia-drm-linux.c:  MODULE_LICENSE("Dual MIT/GPL");

Thank you! (Just wanted to add that not even akmod-nvidia-open works for me at the moment – same error). So (without the dirty fix) it’s basically currently not possible to install an nvidia driver with the latest rawhide.

10

nvidia open works fine with the rawhide kernel, your card is too old and isn’t supported by the nvidia open.

Maxwall, Pascal and Volta gen cards are likely to become legacy later this year.

This should compile, it has the gpl hack included.
