From 19c91044e44dd31deaeb638a919c64e9a9182448 Mon Sep 17 00:00:00 2001 From: Peter Hutterer Date: Tue, 5 May 2015 14:17:10 +1000 Subject: [PATCH xf86-input-libinput] Use the new unaccelerated valuator ValuatorMask features SDL Games like openarena rely on relative input that's handled by the DGA code in the server. That code casts the driver's input data to int and sends it to the client. libinput does pointer acceleration for us, so sending any deltas of less than 1 (likely for slow movements) ends up being 0. Use the new ValuatorMask accelerated/unaccelerated values to pass the unaccelerated values along, the server can then decide what to do with it.
