You have a powerxpress or hybrid laptop that has two GPUs.  Depending
on the vendor there is either a mux to switch between which card is
connected to the displays or the radeon card is only used for
rendering and only the intel card is attached to the displays.  Newer
X servers (1.14 and newer) support rendering with the offscreen gpu.
