dual-headed desktops are well supported by a variety of cards. dual
1600x1200 LCD's connected via DVI are less well supported but
there are cards that will do it, e.g. the matrox parhelia or some of
nvidia's high end cards.
are there any near-commodity display adapter pairs that will
support four 1600x1200 LCD's via DVI? e.g. one AGP card and
one PCI card? if there are, can the pair be controlled
by one X server instance? if it can, would xinerama work across
all four displays? what kinds of programs would fail to run or
would not run well because of the slow (busy) PCI data path to
the PCI adapter instance?
if two X server instances are required (one for each adapter), can
you run xinerama on each X server instance, yielding two logical
displays from four physical LCD's? would there be a way to let
the mouse track from one logical display (left-most pair of
displays) to the other (right-most pair of displays)?
thoughts/comments?
