Linux gaming has come a long way, thanks to Protonge, a compatibility layer developed by Valve. It enables users to run Windows-only games on Linux via Steam Play. However, some games refuse to launch, causing frustration among players. This guide will help you troubleshoot and resolve these issues effectively.
Why Games Won’t Launch with Proton?
Several factors can prevent a game from starting. These include missing dependencies, incompatible Proton versions, or outdated drivers. Understanding the root cause is crucial to finding the right fix.
Another reason could be ProtonGE, a community-built version of Proton. Some games run better with it, offering patches and improved compatibility. Installing and using ProtonGE can sometimes resolve stubborn launch issues.
Check and Update Your System
Ensure your Linux distribution is up to date. Outdated software or missing system libraries can lead to compatibility issues. Run system updates using the terminal commands below:
Also, update your graphics drivers. NVIDIA, AMD, and Intel provide official drivers that improve performance and compatibility with Proton. Use your package manager or download the latest drivers from the vendor’s website.
Use the Right Proton Version
Steam allows users to switch between different Proton versions. Some games work better with older releases, while others need newer updates. To change Proton versions:
- Open Steam and go to your Library.
- Right-click the problematic game and select Properties.
- Navigate to Compatibility and check Force the use of a specific Steam Play compatibility tool.
- Choose different Proton versions, including Fix Games won’t Launch with Proton” and test which one works best.
Enable ProtonGE for Better Compatibility
ProtonGE (Glorious Eggroll) is a custom fork of Proton that fixes many issues. It includes patches, better DirectX support, and enhanced performance tweaks. To install ProtonGE:
- Install ProtonUp-Qt, a tool that manages custom Proton versions:
- Open ProtonUp-Qt and install the latest ProtonGE version.
- Restart Steam, then set ProtonGE for the game in the Compatibility section.
Using ProtonGE can resolve many launch issues, especially for newer or demanding games.
Check for Missing Dependencies
Some Windows games require additional software like Microsoft Visual C++ Redistributables or .NET frameworks. These dependencies might not be installed automatically, causing launch failures.
To install missing dependencies, use Protontricks:
Select the game and install required libraries. Restart Steam and try launching the game again.
Run the Game in Windowed Mode
Some games fail to start in full-screen mode due to compatibility issues. To force windowed mode:
- Right-click the game in Steam and go to Properties.
- Under Launch Options, enter:
-windowed -noborder - Save and try launching the game.
This simple tweak has resolved launching problems for several users.
Disable Steam Overlay and Other Background Apps

- Navigating to Steam > Settings > In-Game.
- Unchecking Enable the Steam Overlay while in-game.
- Restarting Steam and trying again.
Additionally, background applications like Discord, OBS, and screen recorders may conflict with Proton. Close unnecessary apps before launching the game.
