Gotta mention Pop_OS! as a fantastic beginner distro. My 72 year old mother refuses to use anything else. It’s simple, has automated backups and disaster recovery, and installs non-free drivers for graphics cards.

I don’t personally use it since it doesn’t yet support Wayland and my gaming rig has a HiDPI screen and X11 doesn’t support fractional scaling. Or per screen scaling.

I’m legally obligated to inform you that I run Arch.
