Well, I disagree. I would say, Voodoo 1&2 boards don't have _obvious_
2D support. That is, the input (typically Glide API) is 3D. But the
output is 2D, right ? So now suppose I write (well I didn't write it !)
a description of the plane which is my X desktop, in Glide... You see
where I'm heading, don't you ? Yes, the output will be a (slow) 2D X
server. But it works !
And actually, someone in the XFree86 team coded that. If you look on
xfree86.org, on the driver status, you'll see :
4.0:
Support for Voodoo 1 and Voodoo 2 via glide on platforms where glide is
available (Linux and FreeBSD(?)). Support is
provided by the "glide" driver (requires Glide 2x).
Support (including acceleration) for Voodoo Banshee and Voodoo 3. Support is
provided by the "tdfx" driver.
This is for 2D, not 3D. The Voodoo2 is not concerned with GLX or DRI
stuff afaik. And in the release note, you'll notice this "glide"
driver.
The thing is, to use dual-head, you have to have the two (2D) cards
initialised at boot. Which doesn't happen on my machine (Mach64 + TNT2).
The soft boot doesn't seem to work either. Weird stuff happens when I
try to use the Mach64, though it gets detected. That's where the Voodoo
makes the difference. It's not a "graphic" board, but a multimedia
device. As such, it gets initialized at boot time. And will work for a
dual head environment once I find this glide_drv.o ! I think I'll have
to recompile myself, in the end...

Well, I hate to hear that, "once Nvidia releases its XFree server" !
They seem so busy with the Win2000 video drivers these days. I wonder
when they are going to release the full documentation so the Utah-GLX
people can produce a decent GLX module. The only thing I've seen so
far is : on q3 and UT, my Voodoo2 beats the TNT2/GLX anytime.

I know that, I've had it working for almost one year !

Not really, but thanks anyway !
