Although we've been discussing the *free* X server XFree86, which may or may
not be helpful to the person interested in running DX under Linux, I might
mention that there are a couple of commercial X servers which do claim to
support 3D accelerated hardware for certain chips. In particular, there's
Extreme3D by MetroLink which will work (they say) for some Glints (3Dlabs) and
a Permedia chip. This product also comes with a certified OpenGL implementation.
It's not quite ready yet but it appears they have a beta version for one
3Dlabs chip. MetroLink also sells a "real" Motif for Linux (and *BSD).
I'm not affiliated with MetroLink in any way, I haven't even ever tried their
product, but depending on the needs of the (original, unnamed) individual who
asked about Linux, this sort of thing might be an option if funding is
available. The products don't seem to be all that expensive. MetroLink is
at www.metrolink.com. Xi Graphics (www.xigraphics.com) also has something in
the offing (also not quite ready yet) but I know even less about them -- they
seem to concentrate mainly on laptops.
