I used Linux desktop as my work rig for a year and a half. I absolutely hated it, had constant problems and lost time almost every day to stupid workarounds. When I tried to search or ask for help the answer I was usually met with was "your hardware is wrong" or "why do you want to do that" or more often than no "you're using the wrong distro, you should use [different one every time]". I also found the UI to be quite ugly and often obtuse, you can tell that there's very few open source UI/UX designers. I switched back to windows and I've had better performance and less bugs.
Do you feel like you ever got over the initial setup period? A lot of what you are describing is what I encounter after a fresh install but I don't typically have any issues after a little bit of tweaking.
Maybe because it was a work laptop I didn't spend as much time on setup as I would for a personal computer. There's were a lot of issues that I solved with tweaking at the start, but many of the lingering issues either had no solution or were so intermittent or complex that I couldn't figure out how to word it in a way that would lead me to the solution.
