I fetched, built and ran the latest iio-sensor-proxy. It quit with the following error. However, immediately afterwards, I ran the Debian packaged version (1.1-1), and the sensors started to work. Something in the latest master activates the sensors enough for the older version to work. To make sure it wasn't fixed by a kernel upgrade, I also rebooted and tried again: 1) Booted system - iio-sensor-proxy.service running --- No rotation sensing 2) # systemctl stop iio-sensor-proxy-service --- Turn off the agent 3) # G_MESSAGES_DEBUG=all /usr/bin/iio-sensor-proxy.orig ---- original version, still not working 4) # G_MESSAGES_DEBUG=all /usr/bin/iio-sensor-proxy.new ---- latest master, failed with error messages 5) # G_MESSAGES_DEBUG=all /usr/bin/iio-sensor-proxy.orig ---- original version, suddenly working All of this was tested on
