The sad state of being able to use Ubuntu on touch devices (hint: you
can't)
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1807250
So, apparently support for an entire bus class has been missing since
ubuntu bionic (18.04 LTS) was released in april. Using kernels from
other distros or ubuntus old xenial 4.4.0-134 all provide access to
sensor data, suggesting the issue is with current (and shipped) kernels.
Three weeks into this not much is happening even though the issue also
affect canonical-specific 4,18 kernels.
This all suggests that pretty much no one has been using ubuntu on touch
devices otherwise i wouldn't be the first one to notice this. Now that
the devs know this they have no time for it...

Title:
At some point in the 18.04 cycle, /sys/bus/iio has disappeared from my
system
Status in gdm3 package in Ubuntu:
New
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have a Yoga 900-13ISK and a Thinkpad T470s. 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.
