Both have had working screen rotation in the past. However, I noticed today while supporting a user in #ubuntu, neither do now. No icon in the Gnome menu and: # G_MESSAGES_DEBUG=all iio-sensor-proxy ** (process:14877): DEBUG: 12:31:21.603: Could not find any supported sensors Indeed, /sys/bus/iio does not exist! I believe this is distinct from LP: #1792813, as I have just tested mainline 4.19 and it also does not work. I am working on getting more data, including testing older kernels from 18.04, but it might take me some time.
