@Boris, it's probably better you followup on these bug threads more specific to 
your Notebook and touchpad device:

I don't think you have the same issue, the problem in bug 1526312 is a
touchpad with missing descriptors.

I think what you are seeing is the same i2c-hid touchpad power-
management issue as other people or seeing on various ezbook models.
This is currently being discussed here:

https://bugzilla.kernel.org/show_bug.cgi?id=199821

The touchpad should work after a suspend/resume. You may need to do:

sudo rmmod i2c-hid
sudo modprobe i2c-hid

After suspend-resume.

Title:
  Touchpad stops working after reboot on Apollo Lake

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Triaged

Bug description:
  On the Jumper EZBook 3 Pro (V4) laptop, using an Apollo Lake N3450
  processor, if you install Ubuntu 17.10 (or less) with isorespin and
  use rEFInd as bootloader (this is the only way to get linux booting on
  this laptop) everything works out of the box, but after a reboot or
  two the touchpad stops working. Both in Ubuntu and Windows 10. The
  only way to restore functionality is to boot from usb key ubuntu 17.10
  respined, or disassemble laptop and detach-reattach battery cable.
  This is mesg | grep i2c_hid:

  There has to be a bug in the kernel. Any way to avoid this?
