Public bug reported:

Binary package hint: xserver-xorg-video-nouveau

With the nouveau driver, my screen is forced to 96 DPI (as reported by
‘xdpyinfo | grep resolution’), and fonts look too small.  This did not
happen with the binary nvidia driver, which correctly detects my 129×127
DPI display.

>From /var/log/Xorg.0.log, it seems that the driver is detecting the
correct panel size from EDID, but overriding it with a size computed
from 96 DPI for no apparent reason:
