Valve put up a new Steam Linux Runtime 4.0 with a move towards 64-bit (www.gamingonlinux.com)

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.

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?

[–] _cryptagion@anarchist.nexus 4 points 1 week ago

too many small things over the years to go over them all in one post. some still relevant, some not. drivers, for one. no game mode, if I remember correctly. you might end up having issues with controllers, and VR is out of the question on the flatpak. some people have reported issues with permissions.

it's enough of a troublemaker that Bazzite blacklisted the flatpak, I believe, and it can't be installed normally.

For me personally (Fedora 43 KDE) about 80% of unity games that don't have a native build refused to run at all. No problems at all since I swapped to a non-flatpak Steam install.

OTOH I'm having trouble with pretty much all flatpak apps in some way or another... might just be my system that's being weird.

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, I guess?

You're saying that I am the ton of problems they were referring to? 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.

[–] who@feddit.org 2 points 1 week ago

Thanks for clarifying. :)

is unsupported by Valve

You say that as if the versions packaged by your distro are supported.

As it stands, on Linux, Steam is only supported by Valve on SteamOS and LTS releases of Ubuntu.
