Computer -> System Configuration -> Screen Resolution should not only allow to
set widht, height, and frequency, but also the physical resolution of the
monitor. A friend of mine got 1600x1200 as default resolution, which makes
characters far too small to be readable.

Instead of specifying a DPI number directly (which is somewhat abstract), there
should be two rulers displayed; either the user measures them with a "hardware
ruler" and enters the lengths of the displayed rulers (much like GIMP does), or
there is a slider for each direction which scale the displayed rulers until they
match the hardware ruler.
