I think I am -- Plug & Play detects it with the correct name and i/o ports. I
also tried selecting the driver specifically instead of using the plug and
play functionality - which is how's it's set now. It's using the same driver
in both cases, I think, with no change in behavior.
The driver for my card is part of the glint module. One curiosity with the
driver was -- that initially when Mandrake detected my card and configured X
-- it didn't create any mode lines for it, and X came up in 640x480 at 60hz.
I have discovered that this version of X appears to have a bunch of modes
pre-configured (or is that a feature of the video driver?), none of which,
though, were really suited to my card and monitor combo, so I had to do some
searching online about writing mode lines, which I did, and I optimized them
with xvidtune. Other than the snow on the screen (which appeared even in
640x480 60hz), the modes all work well.

I'm using a driver from the card manufacturer in Win"sux" .. it works fine, so
that's not an issue.

Thanks for lending your ear and experience!

I added the Xv module since it was recommended by one app or another, but the
problem exists with or without that module loading.
Thanks!
