From f60e0f390334c5cb03bc89b249ff20dda0574b30 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 2 Jul 2017 15:36:59 +0200 Subject: evdev-mt-touchpad: Enable timestamp smoothing support for bluetooth touchpads Bluetooth wreaks havoc with the timestamp of the input events coming from the touchpad, enable timestamp smoothing support to counter this.
