Hi
I wrote this text to #1722379, but I think it worth to mention it here
as well.
Recently, after some updates - unfortunatelly I don't know exactly which
updates, but in the last month - I also have the same problem.
The workaround above with the # rmmod i2c_hid && modprobe i2c_hid works, but
I don't think this is the same bug and new bug report should be opened.
I've reported problem here back in October 2017 with my laptop and
problem was solved with kernel upgrade on Artful. Recently I upgraded
same laptop to Bionic and I am not affected by the bug.

touchpad not working after resume on kernel 4.13
Status in linux
I too am affected now. After suspend+resume, my touchpad isn't found.
Rebooting doesn't help: I really have to turn the machine off and on
again.
I can attach mouse, and then if I try to open touchpad settings in Input
Devices settings (I use Kubuntu), it says that Touchpad isn't found, and
Here's dmesg after resume

This bug has started affecting me on 4.15.0-20-generic #21-Ubuntu. Not
sure if it's been reported on that release, not sure how to report it on
the correct release.

I did the same with:
$ uname -rv
4.13.7-041307-generic #201710141430 SMP Sat Oct 14 14:31:12 UTC 2017
and also this kernel works for me and touchpad works after resume. What
is also nice, Wi-Fi works after resume.

Could you also give the latest upstream stable 3.13 kernel a try? It is
available here:

Let me know do you need anything else. Will be possible to backport
fixes from 4.14 to final release of Ubuntu 17.10, so touchpad works
after resume on default Artful Aardvark install?
