Not exactly the most compelling of arguments. ;-)

Grovelling around in the F15 xorg-server sources and reviewing the Xorg 
log file on my F15 box, I see, with _modern hardware_ at least, that we 
do have the monitor geometry available from DDC or EDIC, and obviously 
it is trivial to compute the actual, correct DPI for each screen.

Obviously in a multi-screen set-up using Xinerama this has the potential 
to be a Hard Problem if the monitors differ greatly in their DPI.

If the major resistance is over what to do with older hardware that 
doesn't have this data available, then yes, punt; use a hard-coded 
default. Likewise, if the two monitors really differ greatly, then punt.

Beyond that I'd say this violates POLA if the data is available and the 
xserver doesn't honor and correctly report it.

And it wouldn't be so hard to to add something like -dpi:0, -dpi:1, 
-dpi:2 command line options to specify per-screen dpi. I kinda thought I 
did that a long, long time ago, but maybe I only thought about doing it 
and never actually got around to it.

My 2¢ worth.
