Not providing any sensible sensor values #276

Closed seijikun closed 5 years ago

seijikun commented 5 years ago

iio-sensor-proxy seems to at least properly detect accelerometer and ambient light sensors, but is unable to provide sensible values for them. (For example: ambient light always reports 0 Lux). Manually reading the raw sensor files in sysfs report proper values.

My System:

KDE auto-rotate already worked once with this notebook, so this could be a regression.

monitor-sensors output:

    Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: undefined)
=== Has ambient light sensor (value: 0.000000, unit: lux)

Here is the log of iio-sensor-proxy when run with debug-messages:
