How to Install Steam on Arch Linux/Manjaro

Prerequisites

Enable the multilib repository by uncommenting the [multilib] section in /etc/pacman.conf:

/etc/pacman.conf[multilib]
Include = /etc/pacman.d/mirrorlist
Plain text

multilib repository contains 32-bit compatible libraries.

Then update the package lists with pacman:

$ sudo pacman -Syy

Installation

Install steam from AUR and choose the provider of lib32-vulkan-driver. (I'll go with lib32-vulkan-intel in my case, since I'm using Intel's integrated graphics. More information can be found at ArchWiki):

  $ sudo pacman -S steam
