well no one can help you with that amount of info dood. what kinda headset you got? whats your specific distro? im assuming you know you probably need a runtime like steamVR. if you dont, download steam, plug in your headset, run the set up. if your having trouble getting the headset to show a display just google "steavr on linux" and youll find a short instruction troubleshooting page on steam that will help you. if youve got all that done, add a non-steam game to your library (this game). after adding it to your library, right click on the game or click the gear icon and bring up the properties page, click compatability, select proton 9.0-4.
your game should run in vr mode now... maybe... like i sad, this is just me assuming what you have because you asked for help but gave absolutely no info.
