Ubuntu installed few weeks ago, but had touchpad problem until kernel change.... 4.13.0.17 is working (from your link above)!!!! 4.14-rc7 was not ok (maybe patch was not included at all, god knows who compiled the kernel)!!! Since yesterday all boot was normal, touchpad is working, no freezing issue. Maybe sometimes this 100ms waiting time is not enough. This waiting time includes in the patch. After some debuging this it seems that this touchpad simply never sends an interrupt after a reset as expected by the i2c hid driver. This commit adds a quirk for this device, making i2c_hid_command sleep 100ms after a reset instead of waiting for an irq, fixing i2c-hid failing to bind to this touchpad.” Maybe this 100ms is not enough sometimes, this was the reason, why your touchpad not worked once.

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.
