Hutterer: X server pointer acceleration analysis
For those who are curious about the rather complex way in which X serverpointer acceleration works, Peter Hutterer has put together a four-partseries on the topic:part 1,part 2,part 3,andpart 4."The 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)".
