Like the title says I am trying to understand how these things should work together. Part of my issue is I don’t have a good mental model on the Flatpak permissioning / sandbox model. My use case is running a game on Lutris, which is a Flatpack, and using my package install of Mangohud. I am also curious if I should using a Flatpak version of Mangohud instead of the package installed version, and understanding how I would set up Steam as a Flatpak in the future when I switch away from the packaged version.

Thanks for any helpful tips or links you can provide.

    I don’t use flatpak but I didn’t have to configure Lutris or Steam in any way for that.

    If you look around goverlay you’ll find that there are two ENVs that you can set up in X/wayland service to have MangoHud automatically in every context it can render in.

    So first try running with MANGOHUD=1 env exported. If that doesn’t help, try mangohud steam.
    If I understand correctly, flatpack run in some kind of container, so it’s possible that you might need to set the env or the command, so it happens inside the container

    I tried so hard to use the Steam Flatpak, but hit a wall when I wanted game libraries on multiple drives. The Arch wiki recommended to use the native binary.

      The easiest way is going to Flatseal, selecting steam and under the folders section add the paths to your libraries.

    Here is my understanding of this now I’ve got everything working on my Flatpak install of Steam:

    MangoHud

    • Mangohud is installed as another Flatpak, org.freedesktop.Platform.VulkanLayer.MangoHud
    • I don’t think I ever installed this manually, I believe the Steam Flatpak will bring this as a dependency
    • To tell a game to use MangoHud you add MANGOHUD=1 %command% to the Steam launch options of the game
    • Alternatively you can use like Flatseal to add MANGOHUD=1 to the Steam FlatPak to get this working in every game by default

    Gamemode

    • You need to install the Gamemode daemon, gamemoded as a system package
    • Once that is installed you can add gamemoderun %command% to the launch options to run the game with Gamemode enabled
