Universal Blue released Bazzite Deck 44, the latest major update to the SteamOS alternative Linux distribution. This update matters because it aligns the handheld gaming stack with Valve's SteamOS, bringing native controller handling and TDP control to Linux gamers. Users who want a console-like experience on handhelds now have a more polished, standardized software foundation to work with.
New controller and power management tools standardize the Linux gaming experience
The distribution is built on Fedora and ships with the Open Gaming Collective Kernel and Mesa 26.2.1. This release replaces the previous controller and power management stack with a SteamOS-aligned approach. The new system uses InputPlumber for controller handling and SteamOS-Manager for session switching and TDP control.
GPU switching now relies on Cadwire, which replaces the older switcheroo and supergfxctl tools. The default terminal emulator is Konsole, which has replaced Ptyxis. The update also removes QEMU and ROCm from standard images, moving those features to Bazzite-DX or Distrobox instead.
Performance tweaks include a vulkan-low-latency-layer for reduced latency in games. The update adds bpftune for automatic kernel network tuning to optimize gaming traffic. Background usage of the Bazaar Flatpack Store has been reduced to 3MB of RAM. MakeMKV and libmmbd are now included for Blu-ray playback support.
Some devices may temporarily lose gyro support, and fan control might be unavailable on certain hardware. The team is developing a plugin to restore these features in the future. ARM handheld users should look to the Armada project for appropriate support.
