i2c-hid and hid-multitouch drivers wake computer during suspend

[Timothy Allen]

Using the latest 16.04 LTS (Ubuntu 4.4.0-64.85-generic 4.4.44), my Dell Inspiron 7548 wakes everytime the Elan touchpad registers a touch. This causes the machine to wake when the lid is closed, and renders the suspend/hibernate function useless.

The only way in which the suspend doesn't respond to the touchpad is if the touchpad is manipulated *during* the suspend process.

This is true when removing the drivers or unbinding the hardware in /etc/pm/sleep.d; removing or unbinding will still cause the laptop to wake from sleep unless the touchpad has been touched between removing the driver and suspending the laptop.

Disabling everything in /proc/acpi/wakeup has no effect on the issue.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.11 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Timothy Allen (tim-treehouse)]

Thank you. Testing on 4.11.0-041100rc1-generic yields exactly the same result, testing with various values of /proc/acpi/wakeup and removed/inserted i2c-hid and hid-multitouch modules: the laptop wakes from suspend upon touching the touchpad unless the touchpad was manipulated between removing the modules and suspending, or during the suspend process.

[Kai-Heng Feng (kaihengfeng)]

IIUC, the laptop wakes up because the screen somehow touched the touchpad when lid closed, right?

[Timothy Allen (tim-treehouse)]

That's correct; the screen presumably touches the touchpad when closing the lid. I've been testing by simply suspending and then touching the touchpad to wake the laptop (it doesn't require pressing the touchpad button; simply registering a touch works).

As I say, the exception is if the touchpad is touched _during_ the suspend process (then the touchpad doesn't wake the laptop), or if the touchpad is touched after unloading the hid-multitouch or i2c-hid drivers. (I initially tried to resolve the issue by forcing removal of the drivers during the suspend processes, but this would also require that I touch the touchpad during the suspend process.)

[Kai-Heng Feng (kaihengfeng)]

From you description, I'd argue that we can't do much here, that's EC's job.

EC should disable the touchpad wakeup when it detects lid is closed, but sounds like your laptop only disable touchpad wakeup when both lid is closed and touchpad is touched.

Instead of
if (lid_is_closed)
   disable_touchpad

Its logic sound like
if (lid_is_closed and touchpad_in_use)
   disable_touchpad

IMO this bug is not related to linux and should report to Dell.

[Timothy Allen (tim-treehouse)]

Thanks; I had been looking at the hid-multitouch and i2c-hid source and was increasingly wondering if it was a BIOS/hardware issue. I'll raise the issue with Dell.
