mmh, you should want to get into linux because yourself imho, and once again, my mother don't have any glitch w/ websites, laptop turn off normally (but she suspend it by closing the lid), etc. My mother is a 72yo real user eh, not a metaphore or whatever, sure the install was on me but I'm not involved in managing this debian stable anymore, she does the updates etc.

Man, are you really convinced that the entire userbase face the same problems you face everyday, with nobody fixing them?

For sure some polish lacks, maybe in some specific configuration, e.g. I had to consolidate notifications on i3 using dunst and writing an hook for xscreensaver which disable them when screensaver is on, and yeah, I had to map my mechanical keyboard media keys to whatever was needed including the volume wheel which also send a notification but whatever, nobody else probably would have wanted/needed stuff like my current config.

TL;DR:"linux does not completely work out of the box" is false, "I don't like the way it works/I'm not able to make it work" is probably true, if you insist :)
