Comment 54 for bug 267241

Thanks for this work Bryce, I think the two-card scenario is
increasingly common and additional robustness in the face of that will
be appreciated by many users.

Is the choice of the card with the "highest busid" the best we can do?
Can X tell if a display is connected to the card, and if one card has a
display, select that? That would handle the case where someone has dual
cards with some sort of bridge, but only one display connected to one of
the cards.

Another common case is laptops that have a high power and a low power
video chipset, both connected to the same screen. I don't know how X
sees that today, or how it handles it.
