This is particularly evident when moving diagonally. There is also undesirable movement when additional fingers enter or leave the touchpad. These patches address these issues by dialing back the fuzz setting, by implementing sensor data smoothing and by discarding movements that directly coincide with a change in the number of fingers detected on the touchpad. Changes since v3: 1: No change 2: Fix loop counter in atp_calculate_abs 3: No change Clinton Sprain (3): input: appletouch: dial back fuzz setting input: appletouch: implement sensor data smoothing input: appletouch: fix jumps when additional fingers are detected drivers/input/mouse/appletouch.c | 114 +++++++++++++++++++++++++++----------- 1 file changed, 83 insertions(+), 31 deletions(-) -- 1.7.9.5
