[PATCH libinput 0/4] pointer acceleration DPI normalization

[Peter Hutterer]

The first patch is just in this series for completeness, it's already been
on this list.

systemd has now merged the mouse DPI hwdb [1], so the next version will come
with that enabled and we just need to start populating the actual database.
The net effect for us is that we can start relying on devices to have a
resolution and build on that. But for that we should start relying on our
defaults to reflect the real world: 400 DPI is simply outdated, most
mice these days come with a 1000 DPI default.

Note that changing the default has no effect on mice until a database entry is
added (and the mouse isn't on 1000dpi). Touchpads are badly affected (see the
comment in 4/4) but that can be hacked around for now until we figure out a way
to adjust the filter code properly.

Cheers,
  Peter
