To ensure games run well on Linux either via Native Linux builds or Windows games with Proton, part of the magic is in the Steam Linux Runtime. A new version of it, the Steam Linux Runtime 4.0 was recently put up with some pretty big changes.

What's the point of it? It ensures Steam and games run through Steam on Linux work properly across all the many different Linux distributions. Another secret Valve sauce for Linux. Well, not secret at all but you get my meaning I'm sure.

Funny this shows up when all of a sudden Steam won't launch anymore on my Arch install. It's installed via flatpak.

How do I even check which version of the Steam runtime I am running? The flatpak version of Steam is just 1.0.something.other.

the flatpak version is unsupported by Valve for a reason. there's been a ton of problems over the lifespan of the flatpak. it's usually highly recommended everywhere not to use that version.

I've been using Steam in a flatpak for a couple years now, I think. What ton of problems are you referring to?

I don't have a reference, but I've been seeing random individuals asking for help and finally saying they fixed their issue by switching away from flatpak, so... You, I guess? Your.problem might be a perfect example of one of the many problems that keep popping up, that seem to only happen on the flatpak version.

You're saying that I am a ton of problems? That's either nonsensical or very rude.

What are you talking about? Running Steam in a flatpak works for me.

Ah, sorry, I confused you for the original commenter. The first sentence is a bit nonsensical, it is a bit rude and snarky, but I meant it as a joke, since I had the wrong impression the person having issues with flatpak steam is asking about issues with flatpak steam.

Thanks for clarifying. :)
