Proton GE (Glorious Eggroll) is a custom version of Proton that enhances game compatibility on Linux. Many users face an issue where Proton GE is not showing on Steam, making it impossible to select for game compatibility. If you're experiencing this problem, follow this guide to resolve it.
1. Ensure Proton GE is Installed Correctly
Proton GE must be installed manually as it is not included with Steam by default. If it does not appear, the installation might be incorrect.
- Download Proton GE from
- Extract the downloaded folder and place it in
~/.steam/root/compatibilitytools.d/. 
- Restart Steam to detect the new compatibility tool.
If Proton GE is still missing, verify that the folder name matches the expected format (
Proton-<version>-GE), as Steam may not recognize an incorrect directory structure.2. Enable Steam Play for All Titles
Steam Play settings must be configured to allow custom Proton versions.
- Open Steam Settings and go to Steam Play.
- Enable Steam Play for all other titles.
- Set the Preferred compatibility tool to Proton GE.
Restart Steam after making these changes. If Proton GE does not appear, check if Steam needs an update, as older versions may not recognize newer compatibility tools.
3. Verify Steam Directory and Permissions
Incorrect directory permissions can prevent Steam from detecting Proton GE.
- Open a terminal and run:
chmod -R 755 ~/.steam/root/compatibilitytools.d/
- Ensure the folder owner is set correctly by running:
chown -R $USER:$USER ~/.steam/root/compatibilitytools.d/
- Restart Steam and check if Proton GE appears in the compatibility list.
If issues persist, try moving the
compatibilitytools.d folder to ~/.local/share/Steam/ instead and restart Steam.4. Update Steam and Proton Versions
An outdated Proton GE Not Showing on Steam. client may not support the latest Proton GE releases.
- Open Steam > Settings > Downloads, then click Check for Updates.
- If an update is available, install it and restart Steam.
- In the Steam Play section, check if Proton GE now appears.
If updating does not help, manually reinstall Proton GE by deleting the existing folder and downloading the latest version.
5. Use Steam’s Beta Client
The Steam beta client often includes early fixes for compatibility issues.
- Navigate to Steam > Settings > Interface.
- Select Participate in Steam Beta Update and restart Steam.
- Check if Proton GE is now available under compatibility options.
If the issue persists, revert to the stable client by opting out of the beta program.
Conclusion
If Proton GE is not showing on Steam, ensure it is installed in the correct directory, Steam Play is enabled, and permissions are correctly set. Updating Steam or switching to the beta client can also help. If none of these steps work, try reinstalling both Steam and Proton GE to restore Backup_and_Restore
