It's tedious for clients to know whether they can call Release* when sensors disappear, or making sure that the device is claimed before releasing it when they go in power save mode. You can now claim the sensor whether it's available or not, and it will automatically start sending out the updates when it appears. Closes #23
iio-sensor-proxy
IIO accelerometer sensor to input device proxy
Installation
make
make install
It requires libgudev and systemd.
Usage
With a new enough version of systemd[1], and a GNOME 3 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
