I've just installed Ubuntu 19.04 on Lenovo Yoga X390 convertible laptop. Autorotation does not work in Gnome Desktop but surprisingly works well during GDM when login prompt is displayed. iio-sensor-proxy service seems to be OK, 

systemctl status iio-sensor-proxy.service
iio-sensor-proxy.service - IIO Sensor Proxy service

sie 25 09:16:17 N317-PC10 systemd[1]: Started IIO Sensor Proxy service.

monitor-sensor can recognize screen rotation well:

monitor-sensor 
Waiting for iio-sensor-proxy to appear
+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: normal)
=== No ambient light sensor
Accelerometer orientation changed: right-up
Accelerometer orientation changed: normal
Accelerometer orientation changed: left-up
Accelerometer orientation changed: normal

But Gnome desktop won't rotate. I believe it is to be done automatically but it does not work. Any hints? Surely I can write a script that runs in the background, monitor monitor-sensor and reacts appropriately to the reported rotation but on my previous Yoga S1 it was working out of the box without any additional setup.

Update 4.12.2019: Seems there is no update to the service sent from the accelerometer. I can manually trigger it via i.e. 

cat /sys/bus/iio/devices/iio:device0/in_accel_x_raw

still it worked and stopped since latest updates, eventually randomly fails.

  • I have the same problem and looked into it briefly a couple of months ago; iio-sensor-proxy working fine and monitor-sensor changing when the screen was rotated, but gnome desktop not rotating. It seemed to be a gnome configuration or dbus problem. In desperation I deleted all the gnome configuration files I could find in my home directory (e.g., ~/.gnome/, ~/.config/gnome*) and – daveraja Apr 16 '20 at 01:13
  • ... and that seemed to fix it. But I subsequently upgraded to 19.10 and it broke again (sensor-monitor still working). This time I haven't bothered with it but if you're desperate give it a try. – daveraja Apr 16 '20 at 01:27
