The quartett of new config functions is: libinput_device_config_accel_get_profiles libinput_device_config_accel_get_profile libinput_device_config_accel_set_profile libinput_device_config_accel_get_default_profile The profile defines how the pointer acceleration works, from a very high-level perspective. Two profiles are on offer, "adaptive", the standard one we have used so far and "flat" which is a simple multiplier of input deltas and provides 1:1 mapping of device movement vs pointer movement. The speed setting is on top of the profile, a speed of 0 (default) is the equivalent to "no pointer acceleration". This is popular among gamers and users of switchable-dpi mice. The flat profile unnormalizes the deltas, i.e. you get what the device does and any device below 800dpi will feel excruciatingly slow. The speed range [-1, 1] maps into 0-200% of the speed. At 200%, a delta of 1 is translated into a 2 pixel movement, anything higher makes it rather pointless. The flat profile is currently available for all pointer devices but touchpads. https://bugs.freedesktop.org/show_bug.cgi?id=89485 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Reviewed-by: Hans de Goede <hdegoede@redhat.com> |
