I would empathize with this issue, but it’s just not been my experience. Most of the time if I’ve done something reasonable I either get no error or a pretty easily google-able one. I’ve been using Linux pretty exclusively for a couple of years. I admit I had help from a guru for the first couple months but then again most of his help came into play with more advanced developer kinds of issues.
That is what I do. I have owned like 4 kvm switches. Even when I paid extra to get a “good” one they never lasted more than like a year or two. My USB switch has been going for about 3 years. Occasionally it glitches out and I have to unplug it from everything but it’s only about every 3-5 months
