Thanks Alan,

Here's what I get with that ...

(II) Setting vga for screen 0.
(**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32
(==) NVIDIA(0): RGB weight 888

(==) NVIDIA(0): Using HW cursor

(==) NVIDIA(0): Video key set to default value of 0x101fe
(**) NVIDIA(0): Using HorizSync/VertRefresh ranges from the EDID has been
(**) NVIDIA(0):     disabled on all display devices.
(WW) NVIDIA(0):
(WW) NVIDIA(0): The IgnoreEDID and NoDDC options have been deprecated.  The
(WW) NVIDIA(0):     NVIDIA X driver makes use of a display device's EDID
(WW) NVIDIA(0):     during construction of its modePool.  It is recommended
(WW) NVIDIA(0):     that you allow the X driver to make use of any available
(WW) NVIDIA(0):     EDID.  If, however, you know what you are doing and have
(WW) NVIDIA(0):     good reason to do so, you can disable the X driver's use
(WW) NVIDIA(0):     of EDIDs by setting the "UseEDID" X configuration option
(WW) NVIDIA(0):     to FALSE; e.g.,
(WW) NVIDIA(0):
(WW) NVIDIA(0):   Option "UseEDID" "FALSE"
(WW) NVIDIA(0):
(WW) NVIDIA(0): Note that, rather than globally disable all uses of the 
EDID,
(WW) NVIDIA(0):     you can individually disable each particular use of the
(WW) NVIDIA(0):     EDID; e.g.,
(WW) NVIDIA(0):
(WW) NVIDIA(0):   Option "UseEDIDFreqs" "FALSE"
(WW) NVIDIA(0):   Option "UseEDIDDpi" "FALSE"
(WW) NVIDIA(0):   Option "ModeValidation" "NoEdidModes"

(WW) NVIDIA(0): See Appendix D: X Config Options in the README for 
details on
(WW) NVIDIA(0):     each of these options.
