Seems similar to #117, however reading the raw values from /sys/devices/pci0000:00/0000:00:13.0/{33AECD58-B679-4E54-9BD9-A04D34F0C226}/001F:8086:22D8.0002/HID-SENSOR-200073.5.auto/iio:device0/*raw works and returns real changing values. Suspending and resuming doesn't change anything.

Any way I can help to further debug this?

Hackily-disabling the trigger device for the accelerometer seems to make it work:

The same issue happens on a Lenovo Thinkpad X1 Yoga. While it worked for a while, at some point I started getting this issue. In my case the ambient light sensor also stopped working, I always get 0.0 lux. My logs:

I'd also like to add some info about the failed to read float from .../io_scale error. I listed the files in the specified directory and there's no io_scale. However there is io_accel_scale. I don't know if that's related.

From https://github.com/hadess/iio-sensor-proxy/blob/master/README.md#known-problems:

Every Linux kernel from 4.3 up to version 4.12 had a bug that made made iio-sensor-proxy fail to see any events coming from sensors until the sensor was power-cycled (unplugged and replugged, or suspended and resumed).

The bug was finally fixed in this commit in the upstream kernel and backported to stable releases. If you experience unresponsive sensors, ask your distributor to make sure this patch was applied to the version you're using.

Please reopen if you still have problems with a kernel containing this fix.
