Steam Compatability layers not showing up in gamescope

[ScarsTRF]

I ran into a few games that need Proton-GE and other few packages, but when installing them into steams extraCompatPackages they ONLY show up inside of desktop mode through either GNOME or KDE, if I try and access them inside of a gamescope session, they don't seem to persist if set or show up anywhere.

Here is how I've installed my compatibility packages:

  programs.steam = {
    enable = true;
    remotePlay.openFirewall = true;
    dedicatedServer.openFirewall = true;
    extraCompatPackages = [
      proton-ge-rtsp
      proton-ge-custom
    ];
  };

Both of the packages you see here are pulled using builtins.fetchTarball and have worked on my desktop, laptop, and in desktop mode

Here's a clip of the list of compatibility layers on gamescope:

Here's another clip of me checking the compatibility layers on Desktop Mode:

This is kind of a weird side effect of how things are implemented, programs.steam overrides the Steam package, but so does Jovian, so we end up with two copies of Steam, one with your overrides and one with ours. I'm not really sure what a good solution would be here...

Since you mentioned that programs.steam is a separate copy, I might remove that. Though wouldn't it just be possible to add another option under jovian.steam to do the same thing? Like jovian.steam.extraCompatPackages?

Why can't jovian override on top of programs.steam.package, and jovian gamescope always use the final steam as input. This also affects #373 btw

It's complicated because other packages in the overlay depend on Steam, so we would have to somehow backpropagate the Steam changes.
