Public bug reported:

On Cosmic, iio-sensor-proxy 2.4, with default 4.18 kernel as well as
latest mainline 4.19.0-041900rc3-generic.

There is no rotation lock button in the gnome-shell panel menu.
Gnome Settings > Device Display shows rotation buttons
There is no directory /sys/bus/iio

Reproduction:
1. Rotate device, fold display back to tent and tablet modes:

-> Rotation is not detected. When folding to tablet mode, device goes to
suspend as if display had been closed normally.

iio-sensor-proxy finds no sensors:
~$ systemctl status iio-sensor-proxy.service
● iio-sensor-proxy.service - IIO Sensor Proxy service
Loaded: loaded (/lib/systemd/system/iio-sensor-proxy.service; static; vendor 
preset: enabled)
Active: inactive (dead)

I reported issue as https://github.com/hadess/iio-sensor-
proxy/issues/236 and was advised:

"Looks like there's no supported sensors, or just no sensors inside this
machine. Nothing that we can do about it, except asking your vendor for
support (eg. is there one or multiple sensors, and if so, why aren't
they supported in the kernel)"

I posted the issue in Dell's Project Sputnik's Google+ community
