With one of the newer updates to X, Xinerama became problematic with an
Intel video chipset, which broke my dual-monitor setup (the second video
card is nVidia-based). After months of living without my dual-monitor
setup to which I had become accustomed, I finally snagged another
nVidia-based PCI cards that I threw in my box. After running "X
-configure", I got a new almost working xorg.conf file; I had to remove
any references to the Intel chipset and it's matching non-existent
monitor, and maybe a couple of other small tweaks, to end up with the
following:

My problem is that X seems to completely ignore my desire to set my DPI
to 96 via the DisplaySize setting of 400x300mms. Instead, xdpyinfo reports:
<snip>
screen #0:
dimensions: 3456x1392 pixels (876x353 millimeters)
resolution: 100x100 dots per inch
depths (7): 24, 1, 4, 8, 15, 16, 32
<snip>
/var/log/Xorg.0.log is perusable at http://www.acu.edu/~westk/Xorg.0.log
Any clues would be appreciated.
