Not much changed even after reverting that commit.


With iio-sensor-proxy, 1.2, I get:

rrs@learner:/var/tmp/Debian-Build/Result$ monitor-sensor 
    Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: right-up)
=== Has ambient light sensor (value: 0.000000, unit: lux)
    Accelerometer orientation changed: left-up
    Accelerometer orientation changed: right-up
    Accelerometer orientation changed: left-up
    Accelerometer orientation changed: right-up
- --- iio-sensor-proxy vanished, waiting for it to appear


Notice that there is no 'normal' orientation mode reported.

Now reverting back to 1.1 of iio-sensor-proxy, I get:

+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: undefined)
=== Has ambient light sensor (value: 0.000000, unit: lux)
+++ Accelerometer appeared
    Accelerometer orientation changed: undefined
+++ Light sensor appeared
    Light changed: 0.000000 (lux)
    Accelerometer orientation changed: right-up
    Accelerometer orientation changed: normal
    Accelerometer orientation changed: right-up


This is on Linux 4.8-rc6.
