I could not get pastebin to give me back a URL so I added my
/etc/X11/xorg.conf below

Basically I'm trying to do the same things with ModeLines that I
have been doing for the last 20 years :-)  I just took the xorg.conf
that was generated during the FC6 intall, added a few Modelines and
Modes lines, and reboot.  The xorg.0.log file does not acknowledge seeing
the ModeLine line but does give errors for the unknown entries in
the Modes line.  Then it defaults to some oddball mode.

The FC6 release notes say:
"The X.org 7.1 X server has been modified to automatically detect and
configure most hardware, eliminating the need for users or administrators
to modify the /etc/X11/xorg.conf configuration file. "

but it does not say that customizing xorg.conf is no longer supported???
Did I make some simple error in editing xorg.conf or maybe this is a
bug in Xorg 7.1.1.  I hope someone did not decide to take this basic
level of configuration away from us users :-)

Thanks for your help.  I am considering writing a non-interactive
version of xvidtune to force my modes.  Is there already some app like
that in the vast X11 software base?
