Found the culprit: it's the Intel GPU.
If I use Intel IGP, the situation is as I described. If I use the nvidia
graphics card, everything works fine with gnome+org, acpi=on.
I've read that support on the IGP for i7-7700HQ on linux is still
ongoing work, so I guess I'll have to wait before I can use it, or do
without touchpad, suspend, etc.

Title:
touch pad stopped working after upgrade to artful 17.10
Status in linux package in Ubuntu:
Confirmed
Bug description:
The touch pad worked fine on 16.10 and 17.04, but it stopped working after
upgrade to artful 17.10.
It doesn't appear with xinput list, and I cannot find any line in dmesg
referring to the touchpad ... so I need help even to report the exact device id!
