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!
Find the make and model of your system and search for it with “Linux”. This is a really easy way to avoid big problems, and finding a suitable distro for said system. It sucks installing a system, only to find out a certain boot flag needs to be turned off, or some kernel has a patch your system doesn’t like. Avoiding all that or even going into the situation prepared is much less stressful.
It also helps to know that with the freedom of Linux, there is a lot of difference in how systems are built, and that is a benefit and not a drawback.
