The problem has been solved. I can now get the HorizSync range passed to
Xorg, but only if I also give a VertRefresh range in xorg.conf. Once this is
done, I don't need modelines, or even modes. I also don't need to pass
NoDDC, either. GL is good, all resolutions are used, all problems seem
The big question in my feeble mind was why this behavior changed between 6.8.2
and 6.9. I use a pretty minimal xorg.conf, actually based off one of the
configuration tools (xorgsetup). Anyway, it seems odd to me that I would not
have to specify VertRefresh in one release, but have to in the next,
especially when it's not produced in the automatic setup tool. Maybe this
should be looked into, or put into the docs, like i810's man file? I don't
know, just thinking aloud...
Anyway, thanks to all for all the help. If anyone has any questions for me,
or an explanation, then let me know. Otherwise, I consider it blessedly
