ublue-os akmods
A layer for adding extra kernel modules to your image. Use for better hardware support and a few other features!
How it's organized
The akmods image is built and published daily. However, there's not a single image but several, given various kernel support we now provide.
The akmods package is broken out into three akmod "streams":
common- any kmod installed by default in Bluefin or which was originally in main pre-39extra- primarily for kmods used in Bazzite or any others we need, but don't fit incommonnvidia- only for the nvidia kmod and addonszfs- only for the zfs kmod and utilities
Feel free to PR more kmod build scripts into this repo!
Features
Overview
The common stream image contains related kmod packages, plus:
ublue-os-akmods-addons- installs extra repos and our kmods signing key; install and import to allow SecureBoot systems to use these kmodsublue-os-ucore-addons- a slightly lighterublue-os-akmods-addonsfor CoreOS/uCore systems
The nvidia stream image contains
ublue-os-nvidia-addons- installs extra repos enabling our nvidia support- nvidia container selinux policy - uses RHEL9 policy as the closest match
- nvidia-container-tookkit repo - version 1.14 (and newer) provide CDI for podman use of nvidia gpus
ublue-os-ucore-nvidia- a slightly lighterublue-os-nvidia-addonsfor CoreOS/uCore systems

Notes
We do our best to support all current builds of Fedora, current versions of the kernel modules listed, and the latest NVIDIA driver.
Note: NVIDIA legacy driver version 470 is no longer provided as RPMfusion has ceased updates to the package and it no longer builds with kernel 6.8 which has now released for Fedora 39. Also the -550 extra driver version tag has been removed as the latest driver will always be included.
The majority of the drivers are tagged with KERNEL_TYPE-FEDORA_RELEASE. NVIDIA drivers are bundled distinctly with tag KERNEL_TYPE-FEDORA_RELEASE-NVIDIA_VERSION.
| KERNEL_TYPE | FEDORA_RELEASE | TAG |
|---|---|---|
| Fedora stock kernel | 39 | main-39 |
| 40 | main-40 |
|
| patched for ASUS devices | 39 | asus-39 |
| 40 | asus-40 |
|
| patched fsync | 39 | fsync-39 |
| patched Microsoft Surface devices | 39 | surface-39 |
| 40 | surface-40 |
Usage
To install one of these kmods, you'll need to install any of their specific dependencies (checkout the build-prep.sh and the specific build-FOO.sh script for details).
For common images, add something like this to your Containerfile, replacing TAG with one of the something-FR tags above:
COPY --from=ghcr.io/ublue-os/akmods:TAG /rpms/ /tmp/rpms
RUN find /tmp/rpms
RUN rpm-ostree install /tmp/rpms/ublue-os/ublue-os-akmods*.rpm
RUN rpm-ostree install /tmp/rpms/kmods/kmod-v4l2loopback*.rpmFor extra images, add something like this to your Containerfile, replacing TAG with one of the something-FR tags above:
COPY --from=ghcr.io/ublue-os/akmods-extra:TAG /rpms/ /tmp/rpms
RUN find /tmp/rpms
RUN rpm-ostree install /tmp/rpms/kmods/kmod-facetimehd*.rpmFor NVIDIA images, add something like this to your Containerfile, replacing TAG with one of the something-FR-NVV tags above:
COPY --from=ghcr.io/ublue-os/akmods-nvidia:TAG /rpms/ /tmp/rpms
RUN find /tmp/rpms
RUN rpm-ostree install /tmp/rpms/ublue-os/ublue-os-nvidia*.rpm
RUN rpm-ostree install /tmp/rpms/kmods/kmod-nvidia*.rpmThese examples show:
- copying all the rpms from the respective akmods images
- installing the respective ublue specific RPM
- installing a kmods RPM.
Adding kmods
If you have a kmod you want to contribute send a pull request by adding a script using build-kmod-wl.sh as an example.
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, replacing RELEASE with either 39 or 40:
cosign verify --key cosign.pub ghcr.io/ublue-os/akmods:RELEASEMetrics
