I've been trying to educate myself about starting with Linux, having invested in a new computer specifically for Mint Cinnamon Edition.... I also got confused when I first made this post, so thank you to @unklebonehead for helping focus my brain: I am using Manjaro ARM on a Pinebook Pro laptop, which I am quite quite stuck with!
Currently, the Updater and the Camera-attaching facilities are stuck - or I am stuck with them! - and I'm not managing to find any suitable help online.... All the tech language is too far beyond my comprehension, so it is really hard to get started!
Dear Unklebonehead has pointed me in the right direction, and I'm signing up with the Manjaro Linux Forum pages... Let's see how I get on!
