Comment 17 for bug 1738491

Okay, i created a respinned ubuntu 16.04 iso with a mainline kernel(4.15.0rc9)

So if i just push the suspend button instead of closing the lid, i can wake up the device.
And the touchpad starts working after waking up.
Movement works
Tap works
Left/Right button not

Looks like this issue is really the same as the other bugreport what you mentioned
