We have the lid and base sensors correct in relation to each other.
e.g., when at 90 degree lid angle, this reports correctly:
# ectool motionsense lid_angle
Lid angle: 90
But it appears that our axes are opposite from (e.g.) what Chrome
expects. With the lid angle at 180 degrees flat on a desk, I see:
# ectool motionsense
Motion sensing inactive
Sensor 0: -571 1018 -16302
Sensor 1: 0 0 0
Sensor 2: 896 -3424 -16208
but the Z-axis should be positive. After this patch, I see:
# ectool motionsense
Motion sensing inactive
Sensor 0: 580 -1000 16289
Sensor 1: 0 0 0
Sensor 2: -832 16368 1008
Which looks more accurate, and actually gets Chrome to rotate properly.
All tested on kevin rev3.
