While Half-Life: Alyx isn't on Linux (yet—it's coming), Valve are still trying to get it working as good as possible with Steam Play Proton and a new update for SteamVR is up.
This is a SteamVR Beta, so you're going to want to opt into that if you're not already. How to do that? Simply search for SteamVR in your Steam Library (it's in the Tools section), right click on it and go to Properties and then to the Beta tab to select it from the dropdown:
Here's the essential HL:A fixes in SteamVR Beta 1.11.1:
- Fixed a memory leak in HL:A loading screens
- Fixed a GPU memory leak in HL:A loading screens on Linux based system
- Fixed a HL:A crash
There were a lot of reports of it crashing, so hopefully this will make it a smoother experience until the expected Linux version with Vulkan sometime later. Nice to see Valve react so quickly though for Linux gamers who own a VR kit! Considering the high price, seeing such support is nice.
More was added to this SteamVR beta too including microphone volume and mute controls in the dashboard, a new audio mirroring beta feature, a new "Far" dashboard position option and other bug fixes.
