Yeah, I was using Linux Mint at the time. Which is based on Ubuntu... So that's often where I'd look for help.

Though any kind of documentation is like Linux, scattered and inconsistent. And I'm "OK" with that, as in I think the way that Linux came to be and is maintained, and provides user choice is also the reason why it's not "user-friendly" in every scenario. You can choose your distribution, and a lot of other things. And then look in a wide variety of places for bug reports, user questions, etc. You'll get a variety of answers from "it just works for me" to "change your distribution that you chose" to "even though some guides say to use Lutris, it's easier to just put it in Steam's external program launcher and choose Proton version x.yz."

Even then, not everything will work because it wasn't written to work (for Linux). It was written to work for Windows, and then some smart people rolled up their sleeves and found ways to make a great many things work for Linux, and it's all amazing. And I find using Linux (mostly) quite pleasant. But when things don't work... there's going to be friction. It will take user effort to find a solution, or a solution might not be found.

And for me personally, being someone who really likes to poke and customize and do things my way, Linux is a blessing and a curse, because I can guarantee I'll hit "weird edge cases" like trying to use the online multiplayer part of a game instead of just single player, or try to use my laptop's brightness controls, but they don't work, or I'll want fractional scaling to work, but it won't. And maybe there's a fix out there, or maybe not. Fixes like "it works for me" or "change your distribution", though, are non-fixes. They just frustrate people. If changing my distribution fixes an issue, how many new issues does it create for me?
