|I was wondering what solution would be best for multi-head displays.

I've been kind of boggled that this is
such a big deal. In 1992, I was running
the Graphics Product Verification Test
(PVT) lab at IBM/Austin for the R/S 6000
line. We did a lot of multi-head testing,
including on occasion one of every type of
graphics adapter we could cram into a big
box. I recall more than once running six
diverse adapters together, including a B/W
and their big dog 3D engine, and various
things in between. We tested them as
separate displays, and as screens of one
display. It tended to all work pretty
seamlessly. Pretty amazing, and *very*
cool. [1]
So was this just IBM's heavily modified
X server, or was this based on common,
multi-head code. Why is this not readily
available in XFree86? Is it the limitations
of the PC architecture?
Thanks,
Miles
