Just got a steam deck and immediately checked out the desktop mode, and I was somewhat surprised to see KDE and pacman as opposed to GNOME and apt, I have nothing against the former though a strong preference for the latter, anyone know why Volvo went in this direction?
They only support Ubuntu as downstream Distro, while they preinstall it on their number 1 supported platform, SteamOS. They control the complete software stack and even hardware.
They dont support Arch on whatever hardware, they support SteamOS on the Steamdeck.
