Eventually there's a setting in /etc/X11/xorg.conf called
"DisplaySize" that does not match the display size of the
monitor. Take a ruler and check. Then, calculate the dpi
resolution from what the manufacturer says about the amount
of pixels in X and Y (e. g. "1200x800").

	           physical pixels x
	dpi(x) = ---------------------
	         display width in inch

and

	           physical pixels y
	dpi(y) = ----------------------
	         display height in inch

The dpi resolution chosen by the X server can be determined
by

	% grep DPI /var/log/Xorg.0.log

This should match the reality.

No, must be somebody else. Name is from Homer's Illias. And,
no, it's not Homer Simpson. :-)
