This is a tricky setup to get working; using two adapters at once with
RandR is uncommon and I know when we first went to RandR 1.2 was
unsupported. I don't know if it's theoretically supported now, but I'm
not at all surprised it's buggy.
It would be much simpler if you could connect both monitors to one
adapter; does neither of them have dual outputs?
