怎么启动hdapsd啊？

chengpq

安装了AUR里面的hdapsd，执行后发现：

bash-3.2# hdapsd -d sda -s 15
WARNING: Cannot open hdaps position input file /dev/input/hdaps/accelerometer-event (No such file or directory). You may be using an incompatible version of the hdaps module, or missing the required udev rule. Falling back to reading the position from sysfs (uses more power). Use '-y' to silence this warning.
open(protect_file): No such file or directory

这是什么问题啊？我应该怎么办？谢谢！

没有/dev/input/hdaps/
难道我什么地方安装错了？
