There are a bunch of games on steam labeled as "playable", but that silently fail when I attempt to launch them. Always the same issue, and it isn't specific to a single game. Binding of Isiac was one of these until recently, where it mysteriously fixed itself while I wasn't paying attention. Titanfall 2 is another, which I'm still struggling with.
If anyones interested, I'll copy paste the steam logs. I'm typing this from my phone, so I can't do that from here.
What gpu do you have?
Have you checked protondb?
What version of proton do you have selected for steam play?
What version of steam are you using? Flatpak, deb/rpm or snap?
I'm using Proton Experimental. While I have checked ProtonDB, I wasn't able to find a solution.
I did find that quite a large number of people suggested I put the following in the launch options:
for var in $(printenv | cut -d= -f1); do export $var=$(echo ${!var} | rev | cut -c1-1000 | rev); done ; OPENSSL_ia32cap=~0x20000000 %command% -window -noborder
I haven't tried any of the other versions in a while, mostly because it takes forever to install, but I can do that. I'll point out that this issue has been going on for years, and I had issues with all variants of steam I've tried before.
I'll download steam a few other times from various package managers to see if any of them work now that some time has passed.
In particular, I'll try rpm-ostree layering, docker, and nix.
(edit)
I've tried installing steam a few different ways.
First, I tried installing with nix.
nix profile install nixpkgs#steam resulted in an error about non-free software that couldn't be bypassed, so I tried devbox global add steam@latest which did work, but only in so much as it installed. It failed to launch steam, never mind any games.
Then I tried docker, since it's what I used prior to flatpak. I first ran
podman pull ghcr.io/ublue-os/bazzite-arch-gnome then
ujust distrobox bazzite-arch ghcr.io/ublue-os/bazzite-arch-gnome
This functioned well, but had the same exact problems as the flatpak version.
I was unable to install the rpm-ostree version. Apparently, Bluefin doesn't include it in the default repositories.
I did test to see if 'brew' had steam in its packages, but unfortunately it didn't.
I played through the entirety of TF2 on Linux a while back, so I'm curious as to what's the issue. Please share more details about your system and steam setup when you can.
