NVIDIA's drivers do not support separate X-screens on a single
card. NVIDIA's drivers use TwinView to display two monitors
on a single card, not Xinerama. NVIDIA's drivers do advertise
the Xinerama protocol so that Xinerama-aware window managers
can get individual head info when in TwinView. From the client's
point of view there is no difference between Xinerama info returned
from NVIDIA's TwinView driver and from a driver that was really
using Xinerama.
