@kisak-valve hi! Unfortunately, this gives me the exact same error. Backlog to be sure

@kisak-valve: now it at least is successful in uploading the dump. But I get the same issue, running LANG=C steam, LANG=C steam-runtime, and LANG=C steam-native.

with dump ID

@kisak-valve: nope, I have en_US.UTF-8 UTF-8, en_US ISO-8859-1, and did generate my locale with sudo locale-gen.

I'm also using Arch Linux and I have pretty much the exact same problem. I've messed with every locale setting I can think of and the en_US.UTF-8 UTF-8, en_US ISO-8859-1 locales are fully enabled. I even have another machine at work with a very similar configuration but it runs Steam fine.. bizarre.

I wish I had something to help you fix the problem but I've been stuck with broken Steam for the last 2 months or so.

So I accidentally created another issue for this (#5184), but it's the same problem five months later. Are there any developments/new ideas I could try?

I've also tried to install the steam client using flatpak (https://wiki.archlinux.org/index.php/steam) but this still didn't make the client work.

Seems like this has to be an issue with my nvidia-340xx and nvidia-340xx-utils video driver for my rather old Nvidia GeForce 9800 GT.

I recently had to switch to the opensource nouveau drivers, and steam worked for a while. But because of flickering issues I had to switch back to nvidia, and now steam won't launch anymore (and I also can't launch the games independently).

Hello @kisak-valve. Yes, I have lib32-nvidia-340xx-utils installed, and the demo mesa packages (like lib32-glxgears) work fine.

Here's a recent example pastebin of the errors I get when running runtime: https://ptpb.pw/K1nX or when running native: https://ptpb.pw/97BM

Also, I've noticed today that the flatpak install does seem to work, but even if I add the ~/.local/share/Steam/ directory to my steam library folders, it doesn't recognize previously installed games (I have given it access to my home directory).

Unfortunately, the desktop system that this issue occurred on has failed, with the motherboard becoming unstable resulting in frequent, irreproducible crashes. The upside is that I'm no longer experiencing this issue on this system ;-).

Hi @kisak-valve, this issue still persists for me, but now on my older laptop:

• it's a Lenovo Thinkpad t420s with an nvidia card that I can switch to with bumblebee
• it has nvidia-390xx-dkms drivers with nvidia-390xx-utils and their lib32 counterparts
• I've tried both steam and steam-native-runtime, both result in the same segfault
• I've tried the flatpak install, which does work but there is a lot of black flickering in the client and games do not work so far

On my work laptop, a Lenovo thinkpad T470s I have none of these issues. It has an integrated intel graphics card, so it may have something to do with the nvidia drivers?

Thanks for the (very!) fast reply! I'm trying to launch it without primusrun/optirun. But just to check the reverse; running it with either of those also results in the same failure.
