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.

Install warehouse. It gives you all the details of which runtime is in a Flatpak and even lets you change the version.

I did not know about Warehouse. Thank you.
