I use KDE Neon on my laptop and I’d prefer to have KDE as a DE on this one too (if possible) but I don’t mind a non Ubuntu base. Basically I’d just like to be able to play games on it without much hassle but I know how to paste commands into the terminal if the need arises.
Could try Nobara, too.
its Fedora based, as well… and I am a blithering idiot and had almost no issues with it.
