Hmm. I'm sure it used to use auto-detect. The lack of a setting for it
is still a bugbear for me, but not really a serious one - I acknowledge
that the number of people who are going to know that they ought to set
the DPI, and know what to set it to, is small, and most such people can
do it with dconf anyway.
(I still think we should consider using auto-detected DPI by default,
though. Laptops are increasingly coming with displays featuring
significantly higher than 96dpi resolution; I'm wondering when the first
2k LCDs will hit.)
I think the X driver sets that value. Here on my laptop it just always
does this:
[ 26.302] (==) intel(0): DPI set to (96, 96)
Regardless if I have my external display connected as well as the
laptop's LCD or not.
