X normally gets its DPI from the line in the file called `Xservers' that looks
something like this:
:0 local@tty1 /usr/X11R6/bin/X -dpi 117 -nolisten tcp vt7
where you can find your proper DPI to put in by taking 1600/screen width in
inches (one inch is 2.54 cm). This affects font sizes, since those are
expressed in points, a unit related to physical measurement rather than
number of pixels.
When using `startx', you can override this value like so: `startx -- -dpi 100'
Depending on how you invoke X, files in different locations may be used. For
example, if I use kdm, which uses /etc/kde3/kdm/Xservers, but if I issue
`startx', it will use /etc/X11/xdm/Xservers.
I don't use gdm, so I can't swear this is correct, but I believe the way to
set the DPI in gdm is to change the line /etc/X11/gdm/gdm.conf (and/or
possibly /etc/gdm/gdm.conf) that reads something like
0=/usr/bin/X11/X vt7 -nolisten tcp
so that it reads something along the lines of
0=/usr/bin/X11/X vt7 -nolisten tcp -dpi 100
(or whatever value is right for you). See man startx, man gdm, man xdm, and
the man pages they point to for more information.
