Nvidia

The purpose of these images is to provide community Fedora images with Nvidia drivers built-in. This approach can lead to greater reliability as failures can be caught at the build level instead of the client machine. This also allows for individual sets of images for each series of Nvidia drivers, allowing users to remain current with their OS but on an older, known working driver. Performance regression with a recent driver update? Reboot into a known-working driver after one command. That's the goal!

These images are based on the experimental ostree native container images hosted at quay.io (repo).

Note: This project is a work-in-progress. You should at a minimum be familiar with the Fedora documentation on how to administer an ostree system.

Core image features:

• Multiple Nvidia driver streams (525xx, 520xx, and 470xx)
• CUDA support
• Container runtime support
• Secure boot
• Hardware-accelerated video playback
• Selinux support
• Multiple Fedora flavors and releases
• Post-install setup with just

Setup

1. Rebase onto the image

   Any system running rpm-ostree should be able to rebase onto one of the images built in this project:

   Note: The image previously titled "nvidia" will not be updated anymore. If you wish to retain the same functionality, switch to "silverblue-nvidia".

   Silverblue (GNOME):

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/silverblue-nvidia:latest
   

   Kinoite (KDE):

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/kinoite-nvidia:latest
   

   LXQt (unofficial):

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/lxqt-nvidia:latest
   

   MATE (unofficial):

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/mate-nvidia:latest
   

   Vauxite (XFCE, unofficial):

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/vauxite-nvidia:latest
   

   Sericea (Sway, unofficial as of Fedora 38):

   Note: The Sway session has some custom configuration options set to improve stability on Nvidia GPUs

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/sericea-nvidia:38
   

   Base (no DE preinstalled):

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/base-nvidia:latest
   

   And then reboot.

   Note: The Fedora release and Nvidia version can be set with the image tag as well:

   	525xx series	520xx series	470xx series (Kepler 2012-2014 support)
   F37	:latest / :37 / :37-525 / :37-current	:37-520	:37-470
   F38	:38 / :38-525 / :38-current

2. Set kargs after rebasing

   Setting kargs to disable nouveau and enabling nvidia early at boot is currently not supported within container builds. They must be set after rebasing:

rpm-ostree kargs \
    --append=rd.driver.blacklist=nouveau \
    --append=modprobe.blacklist=nouveau \
    --append=nvidia-drm.modeset=1

And then reboot one more time!

3. Enable Secure Boot support

   Secure Boot support for the nvidia kernel modules can be enabled by enrolling the signing key:

sudo mokutil --import /etc/pki/akmods/certs/akmods-nvidia.der

Alternatively, the key can be enrolled from within this repo:

sudo mokutil --import ./certs/public_key.der

Rolling back and rebasing

Generally you can perform a rollback with the following:

   rpm-ostree rollback

To rebase onto a specific date, use a date tag:

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/silverblue-nvidia:20230128

Or to rebase onto a specific release, driver, and date:

   rpm-ostree rebase ostree-unverified-registry:ghcr.io/ublue-os/silverblue-nvidia:37-525-20230128

More options for image tags can be found on the container catalog.

Verification

These images are signed with sisgstore's cosign. You can verify the signature by downloading the cosign.pub key from this repo and running the following command:

cosign verify --key cosign.pub ghcr.io/ublue-os/base

If you're forking this repo you should read the docs on keeping secrets in github. You need to generate a new keypair with cosign. The public key can be in your public repo (your users need it to check the signatures), and you can paste the private key in Settings -> Secrets -> Actions with the name SIGNING_SECRET.

Building locally

1. Build container

A container build can be invoked by simply running:

$ podman build \
    --file build.Containerfile \
    --tag build-test:latest
$ podman build \
    --file install.Containerfile \
    --tag install-test:latest

Or to specify the version of Fedora and/or Nvidia driver:

$ podman build \
    --build-arg IMAGE_NAME=silverblue \
    --build-arg FEDORA_MAJOR_VERSION=37 \
    --build-arg NVIDIA_MAJOR_VERSION=525 \
    --file build.Containerfile \
    --tag build-test:37-525

$ podman build \
    --build-arg IMAGE_NAME=silverblue \
    --build-arg FEDORA_MAJOR_VERSION=37 \
    --build-arg NVIDIA_MAJOR_VERSION=525 \
    --build-arg AKMODS_CACHE=build-test \
    --build-arg AKMODS_VERSION=37 \
    --file install.Containerfile \
    --tag build-test:latest

2. Generate signing keys

If you are forking this repo, then you should add a private key to the repository secrets:

$ ./generate-akmod-key
$ gh secret set AKMOD_PRIVKEY < certs/private_key.priv.prod
$ cp certs/public_key.der.prod certs/public_key.der

Using Nvidia GPUs in containers

There is support for enabling Nvidia GPUs in containers. This can can be verified by running the following:

$ podman run \
    --user 1000:1000 \
    --security-opt=no-new-privileges \
    --cap-drop=ALL \
    --security-opt label=type:nvidia_container_t  \
    docker.io/mirrorgooglecontainers/cuda-vector-add:v0.1

Video playback

Additional runtime packages are added for enabling hardware-accelerated video playback. This can the enabled in Firefox (RPM or flatpak) by setting the following options to true in about:config:

• gfx.webrender.all
• media.ffmpeg.vaapi.enabled

Extensive host access and reduced sandboxing is needed for Firefox flatpak to use /usr/lib64/dri/nvidia_drv_video.so:

$ flatpak override \
    --user \
    --filesystem=host-os \
    --env=LIBVA_DRIVER_NAME=nvidia \
    --env=LIBVA_DRIVERS_PATH=/run/host/usr/lib64/dri \
    --env=LIBVA_MESSAGING_LEVEL=1 \
    --env=MOZ_DISABLE_RDD_SANDBOX=1 \
    --env=NVD_BACKEND=direct \
    org.mozilla.firefox
