Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
The moments I have been disappointed by Linux were the moments I learned most about hardware and software.
Linux made me switch the WiFi card of my computer, which is something I’ve never done before and would have deemed “impossible”.
Linux is like a teacher that sometimes slaps you on the hands, but who is always helping you to expand your knowledge.
The biggest thing I fought with since getting started has been audio. First figuring out how to make an Elgato device cooperate (not exactly the most linux-friendly company to say the least), then setting up virtual sinks and routing everything appropriately, and finally getting my mic to not sound like actual garbage.
Frustrating as hell and a very long process to get all of that working out, but definitely learned a lot from it.
I usually blame this on the hardware manufacturers for being secretive gatekeepy fucks that make things only work with shitty drivers
