For example, I saw a post the other day detailing how to set up a Brother laser printer on Kinoite. That’s not something I would have initially considered a potential problem to be solved. Another I ran into some years ago had to do with an Edimax WiFi dongle that used some weirdly specific Realtek 8812 radio, for which you had to set up the driver via dkms. A little prep and knowledge in advance would have saved days of searching online.
I’ve started a personal to-do list of things to research and make sure I have all my ducks in a row before I make the full-time switch on my main desktop, so besides the usual “back up your files” advice, I’m hoping y’all can point out some QoL things I and others may often miss!
Depends entirely on what they do on their device.
If it’s your average user, it should be sufficient for them to know that new software should exclusively be installed through the provided software manager.
Else, they should check if all their software needs are provided by Linux. And also think about which distro would be best for those specific needs. With Distrobox (and Nix) this isn’t as much as an issue as it used to be. But, there’s still software out there (like Davinci Resolve and Waydroid) that doesn’t like to play nice with all hardware and distro combinations.
Perhaps most importantly, ensure it’s a distro with sane defaults for a new user. This doesn’t necessarily mean that everyone should just use Linux Mint. However, it’s better if the chosen distro makes sense for the user.
