Title:
trackpad doesn't work on Lenovo X1 Yoga Titanium after suspend/resume

Public bug reported:
On my X1 Yoga Titanium (which has a fancy new "Sensel" trackpad with
haptic response to clicks), the trackpad stops working after a
suspend/resume cycle, although the red trackpoint continues to work fine
for controlling the pointer. I believe this system is using S0i3 for

seems that my laptop gets into the bad state if I suspend too quickly
after hot unplug from thunderbolt. If I wait long enough after hot
unplug that all the thunderbolt devices are fully removed, then the
system remains fine. If
No BIOS options changed. I am on X1 Yoga 2nd gen - the BIOS exposes S3
by default. X1 Yoga 3rd gen is the first Lenovo generation that
defaults to S0i3 for suspend.

Is MST actually required for 4K / 60Hz monitors, or is HBR2 / DP 1.2
sufficient? (My understanding is that Intel Linux drivers already
support HBR2)

Actually I was wrong about lspci working with the upstream kernel. It
looks like I got lucky once, but the next time I tried it with upstream

So the upstream kernel behavior looks to be pretty much the same as the
Ubuntu kernel.
