Comment 5 for bug 1791427

Thanks for the detail test.

I have another X1 Carbon 6th, but it cann't reproduce your issue.

Could you isolate which change solve this issue?
1, suspend/resume;
2, kernel update;
3, libinput update.

My X1 Carbon's PnP ID is the same as yours, so I think we have the same touchpad.
But the product ID is not the same.
