You can just do it wirelessly, just like you would with any other phone

You can install touchegg to customise touchpad gestures, I learnt it because I also needed it!

Oh I see! I didn’t know Cromite had a desktop version! Thanks for sharing your thoughts :)

What do you think would be the best ~not the simplest~ option?

You can just check on protondb if any game you want to play works with Proton or doesn’t at all. But generally almost anything that doesn’t require an anticheat will work.
