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.

They have to do it for steamos ig

Proton-GE has had the Wow64 feature for a while now that can play older 32-bit titles under 64-bit, so it shouldn't be long before a truly 64-bit steam experience is available.

[–] noisypine@infosec.pub 1 points 8 hours ago

As of Proton-GE 9-22 I still cannot run Diablo II without all the 32 bit dependencies. I hear from people that Wow64 works, but I have never managed to get it to work pure 64-bit.

[–] Kazumara@discuss.tchncs.de 94 points 1 day ago (5 children)

That's a good sign, that Valve is moving at least the runtimes to 64bit only. Maybe that means the client is under similar scrutiny internally. Recently when Fedora was discussing dropping more 32bit libraries Steam came up as a big issue.

[–] Maestro@fedia.io 25 points 1 day ago (4 children)

Yeah, 32bit is why I removed Steam from my Debian desktop daily driver again. I got conflicting 32bit and 64bit versions of some libraries that broke my system. I'm going to try a gaming focussed distro like Bazzite next time.

???

Debian separates out stuff with :[arch] suffixes, and is really flexible in the sense that it even lets you install stuff from completely different architectures for, for example, use with qemu userspace. An i386 package is going to only request i386 dependencies, unless it explicitly specifies an architecture, and vice versa. Arch Linux uses the "lib32-" prefix and I don't really remember how it worked on Fedora but I would imagine something similar. All "gaming focused distros" are merely just their mainstream counterparts with an extra repo for a few packages, it's not going to change fundamentals.

OpenSUSE is the same, the 32-bit stuff is completely separate from the 64-bit stuff, so you won't get conflicts between them.

I just run Steam as a flatpak. Works fine.

[–] 4am@lemmy.zip 20 points 1 day ago (6 children)

Not sure why the downvotes. Flatpak is a great thing.

It doesn't work fine out of the box. I tried it on Opensuse MicroOS a year and a bit ago and had to search 3-5 pretty undocumented solutions to big problems before being able to play the same games that non-flatpak could.

Out of the box, proton didn't work at all.

[–] Quazatron@lemmy.world 1 points 16 hours ago (1 children)

Sometimes you have to allow access to some things outside of the Flatpak container. I use Flatseal for that.

[–] JustEnoughDucks@feddit.nl 1 points 15 hours ago

I don't think flatseal can set the background permission, but I might not recall correctly:

flatpak permission-set background background com.valvesoftware.Steam yes
[–] Holytimes@sh.itjust.works 3 points 1 day ago

Your better off using cachy if you want a gaming focused distro that doesn't break. Unless you use mostly flatpaks. Then bazzite is good

[–] Mwa@thelemmy.club 10 points 1 day ago

Give Steam Flatpak a try on Debian instead.

Any news about an aarch64 version?

[–] Cricket@lemmy.zip 2 points 17 hours ago

Did you see this story a couple days ago? It seems like they're working on it? https://lemmy.zip/post/53357230

The new VR headset runs ARM, so presumably it'll launch with that.
