Have you ever used Linux?

You seem very misinformed so I’m just providing you with resources.

Getting hung up on feature parity with Windows and Mac is both a waste of time and literally impossible given the major differences between those two UIs. KDE already does most of that legwork anyway, and you can disable middle click paste easily.

IMO your time would be best spent making GUI tooling that doesn’t already exist. Identify a pain point for you that forces you to the terminal and start there.

On many distros it is.

Lol I was willing to give you the benefit of the doubt and assume you meant that gamescope would be difficult to get working under Bazzite’s immutable architecture.

You do realize gamescope is just a package you can install, right? Do you think it’s a unique feature of SteamOS or what?

There’s really no reason to use it on a general purpose desktop. It’s designed to basically make a PC into a console. You do still have full access to the (mostly) normal Linux system behind it, but it’s not something I’d use unless I was setting it up for someone who didn’t want to deal with any of the behind the scenes stuff.

CachyOS, Nobara, and Bazzite all should get you the same level of gaming support with more flexibility as a normal OS, and they can all run Steam Big Picture which is basically the SteamOS UI.

Great, yeah, both sides are the same huh? Grow a spine.
