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 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.
