HP Envy x360 - no iio sensors detected

Created by: constantbeginner

Hello there,

on my HP Envy x360 with Ubuntu 19.04 the command udevadm info --export-db does not detect any iio device.

lsmod | grep acc though finds this:

hp_accel               28672  0
lis3lv02d              24576  1 hp_accel

I have tried using sudo systemctl start iio-sensor-proxy which executes without giving any output whatsoever, so does iio-sensor-proxy

gdbus introspect --system --dest net.hadess.SensorProxy --object-path /net/hadess/SensorProxy produces the following error message:

Error: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name net.hadess.SensorProxy was not provided by any .service files

launching monitor-sensor only produces Waiting for iio-sensor-proxy to appear, which is plausible, since no sensor is detected.

What am I missing?
