You're talking about connecting an external screen to a laptop or two monitors on a desktop and using it in only-display/only-laptop/mirror/separate screens mode right?
To be fair, my Thinkpad from work is the first laptop that has issues with when (dis)connecting a screen. When disconnecting I need to turn on the laptop screen before disconnecting; for connecting I can usually log in without screen and use Super+P to switch modes and that fixes it.
But other than this first instance, I never heard of this being an issue and people here talk about it as if it's commonplace. I must have used or seen Linux used on at least 30 laptops with 2 (or more) screens without issue in the last ~10 years, counting the ones at my previous employer as one because they were all the same hardware even if people ran different distributions.
