Steam crashing after launch

General system Applications
1

I installed steam on a fresh EOS install. I used nvidia-utils as I did before. But now the client crashes on launch. Previous forum post fixes either did nothing or the workarounds no longer point to packages that exist.

I tried to look in arch wiki but as far as I see everything related to my problems in the graphics drivers and the troubleshooting sections is out of date. Wich I suspect is the cause of the problem.

Logs say connect to the internet but I have internet (thats how I posted this).

This is just something I would try if a fresh install, delete steam and folders associated to it and then re-install. Before re-installing I would restart (it may not be needed but can’t hurt). TBH steam is the program I get most issues with but the fix is normally easy.

3

Out of curiosity, how did you install Steam?

4

This gives you the idea what is missing as not everything gets installed by default.

Also don’t forget to install vulkan/mesa

5

I tried that. It resulted in the same thing sadly.

6

I have a NVIDIA GeForce RTX 3070 is this still relevant for that? I thinknit itstalls 590 variants of the packages listed in some of the comments of this thread.

7

I tried both Flatpak and Rundime thrpugh packages. I lost patience with the native runtime so didnt install that but I suspect thats not the problem either.

8

I have a 3070ti, 590.xx driver. You need every package for gaming. Just change 580 to 590

9

Me too 3070, laptop, no issues:

Bit of a Frankenstein system, I use the Cachy repos, to the left are all the installed packages that reference “nVidia”.

There’s your problem; Steam is in the official Arch repos. Wipe everything related to Steam from your system, edit your pacman configuration to include multi-lib, then install it with:

sudo pacman -S steam
