Yes, I know. But I'm not talking about the UseBIOS option right now.
I'm talking about the NoDDC option. I did find it documented
on the Internet. For example,
see this link -> http://www.x.org/archive/X11R6.8.0/doc/rendition5.html.
The option was still under development then, and was documented as
a "previews of coming attractions" option. The NoDDC option is referred
to in man savage, but the NoDDC option is not a savage-specific option.
It is a generic option for the "Device" section and should be documented
in man xorg.conf. I have also seen bug reports complaining about the
lack of documentation for the NoDDC option. For example,
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364610.
The above bug report implies that NoDDC is specific to the s3virge driver,
but it is actually a generic option that apparently works with all
drivers. I just tried it on my machine with the nv driver for an
Nvidia video card. It works great! I can now override the DDC2/EDID-probed
values if I want or need to! But why is the option not documented?
Is that X.Org's version of a disclaimer? The man pages for radeon and
savage allude to it, but don't document it. The man page for rendition
actually documents it, but as a "soon-to-be-implemented feature" rather than
as a production option. Oh well, at least it works.
Sorry to rain on your parade, Ron, -- er, I mean shine sun on your
funeral procession -- but you lose this time.
