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

If this had cellular connectivity it could actually be a pretty cool phone. The battery life is probably good too
