I always find this so pedantic, yes, America is the continent but it’s also the name of the country, just like you probably say Argentina, Mexico or Brazil for the countries you mentioned instead of Argentinian Republic, United States of Mexico, or Federative Republic of Brazil. By that same token when you said United States I could have assumed you were talking about Mexico, heck until very recently in history Brazil was also named United States of Brazil so if I or you were old I could also asume Brazil. But I know what you meant by US and you know what he meant by America, stop being pedantic.

What’s your GPU? Nvidia’s you will need to use the proprietary drivers, AMD it depends on how old it is but newer ones should be good with the default driver.

From the issues you mentioned on Ubuntu I think it’s likely you have an Nvidia since it doesn’t play completely nice with Wayland all of the time, which sucks because X11 is halfway out of the window.

Another thing I think you probably know but just in case, you can install different Desktop Environments on the same distro, no need to change distros for that. So you could install Plasma (and yes, Plasma is KDE) or Gnome on your existing mint installation.

Honestly I think Mint is great for beginners and if you’re happy with it there’s no reason to switch. One thing I always recommend though is keeping /home in a separate partition so you can reinstall or switch distros without deleting your data.

That sounds like an awful system to use. I have Arch systems that date back years with unassisted updates, why does it break so much?

No, I drink Earl grey daily, but I didn’t even knew (until a couple of moments ago) that it was Picard’s drink. I first had one on a train in Russia, and fell in love with it. The ones I have today are not the same as that one but still very good.

First to answer your main question if I were you I would try NixOS, because it’s declarative so it’s essentially impossible to break, i.e. if it breaks for whatever reason a fresh reinstall will get you back to exactly where you were.

That being said, I know it’s anecdotal but I have been using Arch for (holy crap) 15 years, and I’ve never experienced an update breaking my system. I find that most of the time people complain about Arch breaking with an update they’re either not using Arch (but Manjaro, Endeavor, etc) and rely heavily on AUR which one should specifically not do, much less on Arch derivatives. The AUR is great, but there’s a reason those packages are not on the main repos, don’t use any system critical stuff from them and you should be golden. Also try to figure out why stuff broke when it did, you’ll learn a lot about what you’re doing wrong on your setup because most people would have just updated without any issues. Otherwise it really doesn’t matter which distro you choose, mangling a distro with manual installations to the point where an upgrade breaks them can be done on most of them, and going for a fully immutable one will be very annoying if you’re so interested in poking at the system.

If you’re really the dev, please add support for spoilers, it’s the only thing that makes me consider a different app. I’ve also been using Boost since Reddit, and I have a feeling spoiler tags worked there, but that was long ago and my memory is not that good.
