Ah, okay well it's the same issue.  -intel also uses xrandr 1.2 (in fact
it was the first driver to gain this capability), and so dual-head
cannot be set up for it using displayconfig-gtk.

The good news is I see this morning, glatzor has already sent in a
change to guidance-backends to avoid the -ati error case.  I'll remind
him we have the same issue on intel.
