iio-sensor-proxy

IIO sensors to D-Bus proxy

Installation

./configure --prefix=/usr --sysconfdir=/etc
make
make install

It requires libgudev and systemd.

Usage

With a new enough version of systemd[1], and a GNOME 3.18 (or newer) based system, orientation changes will automatically be applied when rotating the panel.

Note that a number of kernel bugs will prevent it from working correctly on some machines with the 3.16 kernel (kernel crashes on the Surface Pro, sensor failing to work after suspend on the Yoga Pro, etc.).

You can verify this by running udevadm info --export-db and checking for an output resembling this one:

P: /devices/virtual/input/input15
E: ABS=7
E: DEVPATH=/devices/virtual/input/input15
E: EV=9
E: ID_INPUT=1
E: ID_INPUT_ACCELEROMETER=1
E: ID_INPUT_ACCELEROMETER_ORIENTATION=normal
E: MODALIAS=input:b0006v0001p0002e0000-e0,3,kra0,1,2,mlsfw
E: NAME="IIO Accelerometer Proxy"
E: PRODUCT=6/1/2/0
E: PROP=0
E: SUBSYSTEM=input
E: TAGS=:seat:
E: USEC_INITIALIZED=74243

If that doesn't work, please file an issue, make sure any running iio-sensor-proxy has been stopped: systemctl stop iio-sensor-proxy.service and attach the output of: G_MESSAGES_DEBUG=all /usr/sbin/iio-sensor-proxy
