Description of problem:
Xconfigurator recognizes my Nvidia GEForce 3 card, but fails to
mention that the DVI flat panel interface is not supported by
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Purchase Dell computer with NVidia card.
2.Try to install RedHat 7.3 with monitor connected via DVI.
3.Bang head against wall trying to figure out why X won't work
even though everything looked ok during installation.
Actual Results: I experienced severe frustration until I (fortunately) finally
found an email on some mailing list bulletin board from a
developer at NVidia telling another user that the nv driver
doesn't support DVI.
Expected Results: Xconfigurator (or at least some documentation) should have
me that the support for my card is not complete. Ideally it would
suggest that I use the analog interface or get the driver from
NVidia. I realize the pointer to the other driver is a bit much
to ask, since RH must support billions of cards.
Unfortunately, there is no way for _us_ to know wether or not a given
driver supports DVI or any other feature for that matter. In order to know
what features are supported by each piece of hardware, we would need to
have every piece of hardware, and then go through the X source code completely
every release to determine what features are available both in the hardware,
and wether or not they are supported, and then actually test each feature
to ensure it works.
While that would be nice, it just is not feasible. There is no feasible
way for us to provide users with this information ahead of time.
The best way to know if something is supported, is to ask on
email@example.com, and to search the Internet.
Sorry for any inconveniences you may have been caused by this. Hopefully
in the future, video hardware manufacturers will more directly support
Linux and will write drivers which support all of the features of their

Looks like NVidia DVI support will show up in XFree86 soon:
