I’m running Linux mint. I’ve tried to switch to Linux a few times but after the steam deck/proton and with the approachability of Linux mint I’ve actually managed to fully switch to Linux for my daily driver/ gaming. I still have to dual boot for the rare application or game I can’t get to run but for the most part it worked OOB especially for nvidia users. Plus the Linux mint forms are typically great about supporting new users without alerting the “I use arch btw” Linux horde that will just give you some condescending response and downvote you into oblivion for having the audacity to be new.

Plus the GUI is great and offers an easy out for beginners if they are struggling with changing something via the CLI so you can learn or just say fuck it and use the GUI cause it’s easier. I’ve since tinkered with LM for a while and will likely move on eventually. But it provides the perfect foundation for switching from windows IMO.

As for steam I would say that the local installation using the .deb from steams website works best. But if you rly want to you can use the flatpak but you will run into some frustrating issues regularly and some devastating edge cases so proceed with caution lol.
