Exactly the issue I had on my laptop. Plug in an external display to extend the desktop and the laptop screen turns off. Wasted 6 hours of my life trying to get the damn thing to work properly until I gave up.

Most of Dylan’s talks are good, but I liked this one in particular due to it talking about such a relatively old technology and how we’ve gotten used to some arbetary rules that aren’t in the spec. I feel like it does say that we should be careful with the rules we put in place for things like protocols, since sometimes tougher constraints lead to a less ambiguous experience for users and maintainers.
