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 ProblemType: Bug DistroRelease: Ubuntu 18.10 Package: linux-image-4.18.0-7-generic 4.18.0-7.8 ProcVersionSignature: Ubuntu 4.18.0-7.8-generic 4.18.5 Uname: Linux 4.18.0-7-generic x86_64 ApportVersion: 2.20.10-0ubuntu9 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: mario 2139 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Sun Sep 16 20:20:48 2018 InstallationDate: Installed on 2018-09-13 (2 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Alpha amd64 (20180912) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 0489:e0a2 Foxconn / Hon Hai Bus 001 Device 004: ID 27c6:5395 Bus 001 Device 002: ID 0bda:58f4 Realtek Semiconductor Corp.
