Bug Description
On Cosmic, iio-sensor-proxy 2.4, with default 4.18 kernel as well as latest mainline 4.19.0-
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-
● iio-sensor-
Loaded: loaded (/lib/systemd/
Active: inactive (dead)
I reported issue as https:/
"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
