How to Install Proton on Linux for Steam Play

What is Steam Proton?

Proton is a compatibility layer that allows running Windows games on Linux-based operating systems. Further, it is the same as that of Steam Deck’s Steam OS.

Earlier, playing PC games on Linux required you to run Steam games through software known as Wine. Wine stands for Wine is not an emulator. Valve worked with CodeWeavers, the developers behind Proton. They mixed the technology right into Steam itself as part of Steam Play. It includes Steam’s buy once play on any PC platform tagline.

Valve made Proton after its living-room-focused Steam Machine initiative failed, due to their reliance on a much smaller Linux gaming Library.

How to install Proton (Steam Play) on Linux

We will be using Ubuntu as the main distro for installing Steam as it is one of the most popular versions of Linux. Moreover, you will find this guide valid for other Linux distros as well including Mint.

You can install Steam through the Ubuntu Software store app, but we always recommend using the Terminal wherever possible to help you learn more regarding Linux.

One thing we would like to say is don’t use the Flatpak version of Steam otherwise you may encounter some problems later. Now let’s begin to prepare our system and install Steam, which will further handle all things including Proton. Follow the steps below:

Step 1: First of all, we need to ensure that the Ubuntu multiverse repository is enabled. Use this command to check:
sudo add-apt-repository multiverse

Step 2: Now update the repositories using this command:
sudo apt-get update

Step 3: Now you are ready to install Steam using this command:
sudo apt install steam

Step 4: Now open Steam and enter your Linux account password into the terminal window

Step 5: Log in to Steam using your credentials.

In case you are unfamiliar with Linux commands such as “sudo”, allows us to tell you that it essentially runs a command with the security privileges of the Superuser, i.e., main admin account.

Besides, by default, Ubuntu lets you create your own user account that doesn’t have full system privileges for added security. Advanced Package Tool allows us to install and update software along with requisites from repositories.

Steam Play uses Proton, therefore all you need to do is when Steam is installed, click install on any game, and the client with download all the necessary files.

You may need to clear the filter on your library and that unfortunately is excluding all games that don’t support Linux natively. However, even with the best graphics card, you will need to make sure that Ubuntu is running using the latest device drivers.
