Hutterer: X server pointer acceleration analysis

Post Syndicated from corbet original

For those who are curious about the rather complex way in which X server
pointer acceleration works, Peter Hutterer has put together a four-part
series on the topic:
part 1,
part 2,
part 3,
part 4.
input for the acceleration profile is a speed in mickeys, a threshold (in mickeys) and a max accel factor (unitless). Mickeys are a bit tricky. This means the acceleration is device-specific, the deltas for a mouse at 1000 dpi are 20% larger than the deltas for a mouse at 800 dpi (assuming same physical distance and speed)“.
