I just did this in September. I would second bazzite. I have a Nvidia GPU and I haven’t had a single issue with it. Bazzite is atomic/immutable which makes it more difficult to modify the system or add packages but honestly I haven’t actually needed to modify the system or add any packages. It also has A/B partitions and stores the last OS update so if something gets corrupted or an update doesn’t work you can roll back really easily. I know some people will say if you want to use Linux you need to be comfortable with using the terminal but I haven’t had to touch it.

Back in 2016 I ran Ubuntu on a laptop and I remember having to install everything from apt and tweak stuff. I also remember accidentally messing up my system and having to do a fresh install. Flatpaks have really changed it since then.

You can checkout https://flathub.org to see what apps are available in the built in app store. You can also look at https://protondb.com to see how well specific windows games run on Linux and any tweaks that might help them run better.

I still have a windows partition though since SteamVR doesn’t work on Linux and discord screen sharing doesn’t work on Wayland

I switched to Bazzite on my main PC at the start of September and it’s been great. I only use Windows for steam link vr streaming

I just got a steam deck and I’m surprised how well it runs games. It’s not quite as refined as a switch but it can run games were designed to run windowed in Windows with a mouse and keyboard. It can translate the game to run on Linux, the inputs to a gamepad and convert the game from being windowed to fullscreen. It’s impressive and if the games were actually designed for the deck I feel like it could feel as seemless as the switch.

It is really making me consider Linux for my desktop once Windows 10 reaches EoL. The only game I’ve found that doesn’t work is Destiny 2. Even the desktop mode on the deck is surprisingly nice
