How to Fix Proton-GE Not Detecting Steam on Linux

Introduction

If you use Proton GE to play Windows games on Linux, you might sometimes face an issue where Steam fails to detect it properly. This can prevent certain games from launching or using the correct compatibility layer. Don’t worry this is a common issue and can usually be fixed with a few quick adjustments. In this article, we’ll show you how to fix Proton-GE not detecting Steam on Linux and get everything working perfectly again.

1. Understanding the Problem

Proton GE (Glorious Eggroll) is a custom version of Proton that improves performance and compatibility for Steam games on Linux. If Steam isn’t detecting Proton GE, it usually means one of two things: either the installation folder is incorrect, or Steam hasn’t refreshed its compatibility tools. Occasionally, missing configurations or file naming issues can also cause the detection problem.

2. Check Where Proton GE Is Installed

The most common cause of Steam not detecting Proton-GE is an incorrect installation path. Proton GE should be placed in the compatibility tools directory inside your Steam folder.
If the folder doesn’t exist, create one manually and move your extracted Proton GE files into it. After that, restart Steam to let it detect the new compatibility tool.

3. Enable Proton GE in Steam Settings

Once the files are in the right place, open Steam and go to Settings → Steam Play.
Here’s what to do:

Make sure Steam Play for all titles is enabled.
Open the Proton version dropdown and choose Proton GE from the list.

If Proton GE doesn’t appear, restart Steam again or double check the folder name to ensure it matches the version number exactly (for example, Proton GE Proton9 16).

4. Refresh Steam’s Compatibility Tools

If Steam still doesn’t detect Proton GE, try refreshing its internal compatibility data. This can be done by restarting Steam completely or logging out and back in. Steam will then automatically scan and update its compatibility tools, helping it detect any new Proton GE installations.

5. Reinstall or Update Proton GE

Sometimes an outdated or corrupted installation causes the issue. The easiest fix is to delete your current Proton GE folder and download the latest version from the official Glorious Eggroll GitHub page. Extract it again into the correct folder, then restart Steam.

Newer releases of Proton GE often include fixes for detection problems and improved performance for newer games.

Conclusion

Fixing Proton GE not detecting Steam on Linux is usually simple it’s often just a matter of checking the installation path, refreshing Steam, or updating to the latest Proton GE version. Once properly set up, Proton GE enhances performance, boosts compatibility, and ensures a smoother gaming experience on Linux. Keep your version up to date, and your Steam library will run almost as smoothly as it does on Windows.
