Awww sadly it was just a rumor. https://bsky.app/profile/gamingonlinux.com/post/3lhe2febew22h

Even so, hook up a steam desk to a monitor with a mouse and keyboard and that’s a linux desktop, that’s right now today.

With the advent of the steamOS console, you’re actually correct! If it’s anything like my deck it’s trivial to launch it in desktop mode and use it like a normal linux desktop. This is the gateway to putting linux in front of bored kids everywhere.
