> Secondly, Xorg only does windows, with no sense of importance. What's the problem with that? For a long time, this meant that the Lock Screen was literally just a window, drawn on top of all your other windows. If anything crashed your Lock Screen, system was open for business. This has been heavily hacked and worked around, but it's still a potential threat. Some of the more "lightweight" distributions still use software that is vulnerable to this; because we've sure patched the hell out of that Lock Screen software to please not crash.

I learned this years ago, although not in such detail, and it just blew my mind. You can even see it. I wake my laptop from sleep, my screen flickers and I see my desktop, then the lock screen paints over the top like a flasher closing his coat. It makes me cringe.

Switching to Wayland lasts about 10 minutes though before I find some breakage that prevents me from using it.
