I disagree. The driver cannot tell whether a connected display is powered on or off
Depends on the display, most displays are only detectable when they are actually powered on.
That's not the case at all in my experience. Clearly in this case it's not true, otherwise it wouldn't know the TV was there at all.
, and there is no method for choosing which display is 'primary'
Sure there is .... xrandr provides a way to choose a primary display, so worst case ask the user, or in case of the install just clone the output.
That's not what I meant. I meant that there's no reliable heuristic for knowing which is primary.
Ask the user? How do you pick which display to ask the user on? :)
