I can sympathize but I hate using the controller setup, I’m definitely a mouse and keyboard person. For better or worse I’m stuck with Windows unless Steam comes out with a desktop or something.
What do you mean? You can always use a distro like Steam OS (or any other Linux distro) on any x86 PC and still use a mouse and keyboard. Or use a Steam Deck and plug in a mouse and keyboard.
A steam deck with a mouse and keyboard is kind of horrible, I have tried that. And maybe things have changed, how well does Steam OS do as a primary OS? I might look into it again.
You can use any Linux distro and install steam on it? I really don’t understand the issue you’re having. It works perfectly on pretty much any modern mainstream distro.
