I'm way behind the curve on what's been lost and gained in X configurability
since the massive X overhaul begun roughly 2 years ago. Last I checked on
relatively recent Intel (but not as recent as G45), xorg.conf can still be
used to provide desired configuration that is difficult or impossible absent
an xorg.conf. One such option goes in 'Section "Device"': 'Option "NrRandr"'.
When used, X tends to obey what else is put in xorg.conf regarding display
capabilities. Others that may be necessary to reach a desired end are 'Option
"NoDDC"', DisplaySize, and/or various permutations of EDID/false/ignore
intended to disable EDID.
