[](https://github.com/ublue-os/bazzite/actions/workflows/build.yml) [](https://github.com/ublue-os/bazzite-arch/actions/workflows/build.yml) ## About & Features Bazzite is an OCI image that serves as an alternative operating system for the [Steam Deck](https://www.steamdeck.com/), and a ready-to-game SteamOS-like for desktop computers and living room home theater PCs. Bazzite is built from [ublue-os/main](https://github.com/ublue-os/main) and [ublue-os/nvidia](https://github.com/ublue-os/nvidia), which means expanded hardware support and built in drivers are included. Additionally, Bazzite adds the following features: - Proprietary Nvidia drivers included on the image - Full hardware accelerated codec support for H264 decoding - Full support for AMD's ROCM OpenCL/HIP runtimes - Includes Valve's KDE themes from SteamOS - [LatencyFleX](https://github.com/ishitatsuyuki/LatencyFleX), [vkBasalt](https://github.com/DadSchoorse/vkBasalt), [MangoHud](https://github.com/flightlessmango/Mangohud), and [OBS VkCapture](https://github.com/nowrep/obs-vkcapture) installed and available by default - Support for [Wallpaper Engine](https://www.wallpaperengine.io/en) on KDE. - [Distrobox](https://github.com/89luca89/distrobox) preinstalled with automatic updates for created containers. - Automated duperemove services for reducing the disk space used by wine prefix contents. - Uses [Google's BBR TCP congestion control](https://github.com/google/bbr) by default. - [Input Remapper](https://github.com/sezanzeb/input-remapper) preinsalled and enabled (Available but default-disabled on the Deck variant) - Helpful first-start installer provides an easy way to install numerous applications and tweaks, including installing [CoreCtrl](https://gitlab.com/corectrl/corectrl) and [GreenWithEnvy](https://gitlab.com/leinardi/gwe). - [Nix](https://nixos.org/) package manager optionally available. - [OpenRGB](https://gitlab.com/CalcProgrammer1/OpenRGB) i2c-piix4 and i2c-nct6775 drivers for controlling RGB on certain motherboards. - [GCAdapter_OC](https://github.com/hannesmann/gcadapter-oc-kmod) driver for overclocking Nintendo's Gamecube Controller Adapter to 1000hz polling. ### Desktop Common variant available as `bazzite` and suitable for desktops and HTPCs. - Runs Steam and Lutris in a [custom Arch Linux OCI](https://github.com/ublue-os/bazzite-arch/) via Distrobox. - Ships with a ported version of [System76's Scheduler](https://github.com/pop-os/system76-scheduler), providing automatic process priority tweaks to your focused application and keeping CPU time for background processes to a minimum. - Option to automatically launch Steam in Big Picture Mode on boot for HTPCs. To rebase an existing system to this image: podman pull ghcr.io/ublue-os/config && rpm-ostree install --assumeyes --apply-live --force-replacefiles $(find ~/.local/share/containers -name ublue-os-signing.noarch.rpm 2>/dev/null) && rpm-ostree rebase --uninstall $(rpm -q ublue-os-signing-* --queryformat '%{NAME}-%{VERSION}-%{RELEASE}.%{Arch}') ostree-image-signed:docker://ghcr.io/ublue-os/bazzite:latest or for devices with Nvidia GPUs: podman pull ghcr.io/ublue-os/config && rpm-ostree install --assumeyes --apply-live --force-replacefiles $(find ~/.local/share/containers -name ublue-os-signing.noarch.rpm 2>/dev/null) && rpm-ostree rebase --uninstall $(rpm -q ublue-os-signing-* --queryformat '%{NAME}-%{VERSION}-%{RELEASE}.%{Arch}') ostree-image-signed:docker://ghcr.io/ublue-os/bazzite-nvidia:latest Once you've completed the initial setup of the Nvidia build, [be sure to follow steps 2 and 3 from the ublue-os/nvidia guide](https://github.com/ublue-os/nvidia#2-set-kargs-after-rebasing). ### Deck Variant designed for usage as an alternative to SteamOS on the Steam Deck, available as `bazzite-deck`: - Directly boots to Gamemode matching SteamOS's behavior - Features ported versions of most SteamOS packages, including drivers, firmware updaters, and fan controllers [from the evlaV repository](https://gitlab.com/evlaV) - Patched Mesa for proper framerate control from Gamescope. - Comes with patches from [SteamOS BTRFS](https://gitlab.com/popsulfr/steamos-btrfs) for full BTRFS support for the SD card by default - Ships with a ported copy of [SDGyroDSU](https://github.com/kmicki/SteamDeckGyroDSU), enabled by default - Option to install [Decky Loader](https://github.com/SteamDeckHomebrew/decky-loader), [EmuDeck](https://www.emudeck.com/), and [ProtonUp-Qt](https://davidotek.github.io/protonup-qt/), among numerous other useful packages on installation - Custom update system allows for the OS, Flatpaks, and Distrobox images to be updated directly from the Gamemode UI - Steam and Lutris preinstalled on the image as layered packages. - Comes with a default-disabled service for low-risk undervolting of the Steam Deck via [RyzenAdj](https://github.com/FlyGoat/RyzenAdj) - Exclusively uses zram by default with the option to switch back to a swapfile and set a custom size if desired - Tuned BFQ I/O scheduler to reduce starvation when installing games or during background duperemove processes - Uses CFS scheduler parameters from [TKG](https://github.com/Frogging-Family/linux-tkg) for increased performance - Applies SteamOS's kernel parameters and enables amd-pstate by default To rebase an existing system to this image: podman pull ghcr.io/ublue-os/config && rpm-ostree install --assumeyes --apply-live --force-replacefiles $(find ~/.local/share/containers -name ublue-os-signing.noarch.rpm 2>/dev/null) && rpm-ostree rebase --uninstall $(rpm -q ublue-os-signing-* --queryformat '%{NAME}-%{VERSION}-%{RELEASE}.%{Arch}') ostree-image-signed:docker://ghcr.io/ublue-os/bazzite-deck:latest ## Why Bazzite started as a project to resolve some of the issues that plague SteamOS, mainly out of date packages despite an Arch base and the lack of a functional package manager. Despite this project also being image-based you are able to install any Fedora package straight from the command line. These packages will persist across updates _{^{(So go ahead and install that obscure VPN software you spent an hour trying to get working in SteamOS)}}. Additionally, Bazzite is updated daily with packages from upstream [Fedora](https://fedoraproject.org/) giving you the best possible performance and latest features - all on a stable base. Bazzite ships with the latest Linux kernel and SELinux enabled by default with full support for secure boot and disk encryption, making this a sensible solution for general computing _{^{(Yes, you can print from Bazzite)}}.   ## Custom Packages Ported SteamOS and ChimeraOS packages, among others used by Bazzite, are built on Copr on [bazzite](https://copr.fedorainfracloud.org/coprs/kylegospo/bazzite/) and [bazzite-multilib](https://copr.fedorainfracloud.org/coprs/kylegospo/bazzite-multilib/). |Package|Status| |---|---| |ds-inhibit|| |gamescope-session|| |jupiter-fan-control|| |jupiter-hw-support-[btrfs](https://gitlab.com/popsulfr/steamos-btrfs)|| |mangohud|| |mesa|| |python3-hid|| |ryzenadj|| |sddm-sugar-steamOS|| |sdgyrodsu|| |steamdeck-kde-presets|| |steamdeck-kde-presets-desktop|| |udisks2|| |vpower|| Additionally, the following packages are used from other Copr repos: |Package|Status| |---|---| |[gcadapter_oc-kmod](https://copr.fedorainfracloud.org/coprs/ublue-os/akmods/)|| |[hl2linux-selinux](https://copr.fedorainfracloud.org/coprs/kylegospo/hl2linux-selinux/)|| |[latencyflex-vulkan-layer](https://copr.fedorainfracloud.org/coprs/kylegospo/LatencyFleX/)|| |[noise-suppression-for-voice](https://copr.fedorainfracloud.org/coprs/ycollet/audinux/)|| |[obs-vkcapture](https://copr.fedorainfracloud.org/coprs/kylegospo/obs-vkcapture/)|| |[openrgb-kmod](https://copr.fedorainfracloud.org/coprs/ublue-os/akmods/)|| |[steamdeck-kmod](https://copr.fedorainfracloud.org/coprs/ublue-os/akmods/)|| |[system76-scheduler](https://copr.fedorainfracloud.org/coprs/kylegospo/system76-scheduler/)|| |[wallpaper-engine-kde-plugin](https://copr.fedorainfracloud.org/coprs/kylegospo/wallpaper-engine-kde-plugin/)|| ## Verification These images are signed with sisgstore's [cosign](https://docs.sigstore.dev/cosign/overview/).

Below are some of the people who've helped us along the way: - [evlaV](https://gitlab.com/evlaV) - For making Valve's code available and for being [this guy](https://xkcd.com/2347/). - [ChimeraOS](https://chimeraos.org/) - For gamescope-session and for valuable support along the way. - [Jovian-NixOS](https://github.com/Jovian-Experiments) - For supporting us with technical issues and for creating a similar project. Seriously, go check it out. It's this but built on Nix. - [cyrv6737](https://github.com/cyrv6737) - For the initial inspiration and the base that became bazzite-arch.
