Note

DUE TO RECENT CHANGES IN MANJARO

After install go to Add/Remove Software and remove steam-deckify, then reinstall it and select steam os with HHD session, this fixes the new updates!

Important

You will need a mouse, keyboard, usb drive, and a usb hub (preferably with power passthru, but not required).

This is a unique take of Steam OS on linux.

Installation

Once installed open Konsole, install steam and log into your account.

sudo pacman -Sy 
sudo pacman -S steam

Clone this repository into your Downloads folder

cd ~/Downloads
git clone https://github.com/ripplingsnake/Manjaro-SteamOS.git
cd ./Manjaro-SteamOS

After it's cloned run the first script

chmod +x ./install_first.sh
./install_first.sh 

After it has finished, run it again with sudo.

sudo ./install_first.sh

Important

Open System Settings then go to Startup and Shutdown, at the bottom center left of the window click behaviour. Then and make sure log in again after logging off is checked.
