@bigbox My main computer (desktop) is under Kubuntu, but Ubuntu is iffier as years pass, so I want to change.
I would go for Linux Mint, but they stopped making a KDE version of their distro, so...
As a result, my laptop use a Frankenstein Linux, a Mint Mate with Ubuntu's version of Gnome added to it. Can switch between both DE. (Didn't dare install Plasma on it, maybe I should.)
If anyone know on a distro that is to Kubuntu what the Mate edition of Mint is to Ubuntu-MATE, I will gladly take it.
