The driver exists in the proprietary Steam client, not in SteamOS itself.

You don't need SteamOS. This is strictly a Windows issue and the controller works fine on MacOS and Linux.

> SteamOS is open source, so it's not really walled.

SteamOS is technically licensed under GPL, but Valve has yet to release the source code for 3.0 (4 years ago...)

The last activity in the public kernel repository was 9 years ago.

Where do you see that SteamOS Holo is GPL3? A package is not required to be GPL, and most of SteamOS is a customized arch installation, there's no guarantee that SteamOS itself is GPL. And which repo are you talking about, I don't see it on their gitlab for SteamOS Holo?

As someone else said, the driver is in Steam, not SteamOS. Even on a Steam Deck you have to run Steam in desktop mode to have the buttons on the deck work.

That's not true. You get a reduced functionality controller with trackpads that can still be used to start steam back up.

Its been a minute since I've been on desktop mode, but aren't they just a trackpad at that point and none of the button/haptic functionality exists outside of moving the mouse and clicking?

Essentially yes.

Does that mean that chrome for non standard behaviours are ok because chrome is open source?
