Same issue here on Asus Zenbook Flip UX360UAK with Ubuntu 17.04

[auscompgeek]

@bchernicoff @yoshz Does iio-sensor-proxy work after waking from suspend?

[hadess]

The version of iiio-sensor-proxy used and the output of monitor-sensor would also be helpful.

Description-en: IIO sensors to D-Bus proxy
 Industrial I/O subsystem is intended to provide support for devices
 that in some sense are analog to digital or digital to analog convertors
 .
 Devices that fall into this category are:
  * ADCs
  * Accelerometers
  * Gyros
  * IMUs
  * Capacitance to Digital Converters (CDCs)
  * Pressure Sensors
  * Color, Light and Proximity Sensors
  * Temperature Sensors
  * Magnetometers
  * DACs
  * DDS (Direct Digital Synthesis)
  * PLLs (Phase Locked Loops)
  * Variable/Programmable Gain Amplifiers (VGA, PGA)
 .
 Many ultrabooks ship with some of these devices. iio-sensor-proxy is
 intended to serve as a proxy, providing access to these devices through
 a D-Bus interface

I saw a similar issue and saw some interesting items in the debug log. First I saw this warning in the debug log: (process:12139): WARNING : Failed to read float from /sys/devices/pci0000:00/0000:00:13.0/{33AECD58-B679-4E54-9BD9-A04D34F0C226}/001F:8086:22D8.0001/HID-SENSOR-200073.7.auto/iio:device3/in_scale

I decided to check the referenced sys path to see if in_scale was returning a proper value. I noticed this:

cat /sys/devices/pci0000\:00/0000\:00\:13.0/{33AECD58-B679-4E54-9BD9-A04D34F0C226}/001F\:8086\:22D8.0001/HID-SENSOR-200073.7.auto/iio\:device3/ buffer/ in_accel_scale scan_elements/ current_timestamp_clock in_accel_x_raw subsystem/ dev in_accel_y_raw trigger/ in_accel_hysteresis in_accel_z_raw uevent in_accel_offset name
in_accel_sampling_frequency power/

Notice that in_scale is not present. Could this be an issue that the sys elements changed at a certain kernel level?

I did a cat on in_accel_scale and got 0.000009806

Here is my kernel version: Linux 4.11.6-1-ARCH #1 SMP PREEMPT Sat Jun 17 08:19:42 CEST 2017 x86_64 GNU/Linux

I am running iio-sensor-proxy 2.2

[hadess]

From https://github.com/hadess/iio-sensor-proxy/blob/master/README.md#known-problems:

Every Linux kernel from 4.3 up to version 4.12 had a bug that made made iio-sensor-proxy fail to see any events coming from sensors until the sensor was power-cycled (unplugged and replugged, or suspended and resumed).

The bug was finally fixed in this commit in the upstream kernel and backported to stable releases. If you experience unresponsive sensors, ask your distributor to make sure this patch was applied to the version you're using.

Please reopen if you still have problems with a kernel containing this fix.

[parkerlreed]

Am I missing something? Pure upstream doesn't seem to have that fix. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/iio/common/hid-sensors/hid-sensor-trigger.c

There is no pr_debug anywhere in there.

EDIT: Latest update for that file was on 5/16 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/drivers/iio/common/hid-sensors/hid-sensor-trigger.c

EDIT2: I manually applied that supplied patch to upstream and am building now. Will let you know.

I can confirm that I still need a suspend/wake cycle to make things work (first time I had actually tried that method)

[hadess]

I'm pretty certain you didn't apply the patch properly, or didn't build the kernel properly. Please file a new bug with the debug information requested in the README.

[parkerlreed]

Well crap. I know what happened. I applied the patch but had to cancel that build. Restarted (PKGBUILD/makepkg) and it rebased the source tree against master, wiping out my patch. Thanks for all the help. I assume everything will go fine after another compile. :)

EDIT: All good after the patch!

EDIT2: Either fixing the iio init or some change in 4.13 actually made my touchscreen work better too... exciting updates! :D

[parkerlreed]

@hadess Seems the fix landed in 4.13.3 for me. Thanks again for all the help :)
