Container-Native Linux Gaming on TunaOS

TunaOS gives you an immutable, container-native desktop for Linux gaming, handheld hardware, and emulation.

Key Advantages for Gaming​

  • Atomic System Updates: An update to the OS lands whole, or not at all. It does not leave a half-updated graphics driver behind.
  • Instant Rollback: If a driver update breaks a game, bootc rollback puts the earlier image back at the next boot.
  • Isolated User Runtimes: Install Steam, Heroic, and Lutris as Flatpaks or in a container toolbox. The root filesystem stays as it is.

Quick-Start Setup​

1. Install the Flatpak Gaming Clients​

flatpak install flathub com.valvesoftware.Steam
flatpak install flathub com.heroicgameslauncher.hgl
flatpak install flathub net.lutris.Lutris

2. Add the MangoHud Overlay​

Add the MangoHud layer so that a Flatpak game can show frame timings:

flatpak install flathub org.freedesktop.Platform.VulkanLayer.MangoHud

3. Check the System and the Graphics Stack​

Look at the image you booted and the Vulkan drivers that the system found:
