1. we now detect DisplaySize for more hardware instead of assuming a
fixed size
2. randr drivers broke DisplaSize calculation for yet more hardware that
used to work
3. after years of user complains GNOME finally stopped overriding xorg
dpi calculation with a fixed 96dpi value and started using it directly
(though 96dpi proponents have been quick to seize on all the bugs this
exposed to mount a campaign to go back, while KDE has proved for years
that dynamic dpi calculation could work hassle-free as long as you
taught your app authors not to make stupid assumptions)

But Owen Taylor was quick to get this overrided Red Hat and GNOME side
several years ago.
