4  Pointer acceleration
7 libinput uses device-specific pointer acceleration methods, with the default
18 Pointer acceleration profiles
21 The profile decides the general method of pointer acceleration.
24 of the device into account when deciding on acceleration. The flat profile
27 describes the adaptive pointer acceleration.
54 The velocity is then used to calculate the acceleration factor
62 The acceleration factor is the final outcome of the pointer acceleration
73 moves. This is acceleration and allows a user to cross the screen quickly
74 but effectively skips pixels. libinput's current maximum acceleration factor
80 Linear pointer acceleration
83 The linear pointer acceleration method is the default for most pointer
85 regular movements and a linear increase to the maximum acceleration factor
88 Linear pointer acceleration applies to devices with above 1000dpi resolution
94     Linear pointer acceleration
96 The image above shows the linear pointer acceleration settings at various
97 speeds. The line for 0.0 is the default acceleration curve, speed settings
98 above 0.0 accelerate sooner, faster and to a higher maximum acceleration.
99 Speed settings below 0 delay when acceleration kicks in, how soon the
100 maximum acceleration is reached and the maximum acceleration factor.
102 Extremely low speed settings provide no acceleration and additionally
108 Pointer acceleration for low-dpi devices
112 per inch (dpi). The pointer acceleration is adjusted to provide roughly the
114 pointer acceleration works on device-units rather than normalized
120     Pointer acceleration for low-dpi devices
122 The image above shows the default pointer acceleration curve for a speed of
123 0.0 at different DPI settings. A device with low DPI has the acceleration
124 applied sooner and with a stronger acceleration factor.
129 Pointer acceleration on touchpads
132 Touchpad pointer acceleration uses the same approach as the
141     Pointer acceleration curve for touchpads
143 The image above shows the touchpad acceleration profile in comparison to the
149 Pointer acceleration on trackpoints
161 trackpoints will generate different speeds and thus different acceleration
174     Pointer acceleration curves for trackpoints
176 The image above shows the trackpoint acceleration profile for the speed in
182 The flat pointer acceleration profile
185 In a flat profile, the acceleration factor is constant regardless of the
193 Pointer acceleration on tablets
196 Pointer acceleration for relative motion on tablet devices is a flat
197 acceleration, with the speed setting slowing down or speeding up the pointer
