[Bug 1959728] Re: trackpad doesn't work on Lenovo X1 Yoga Titanium after suspend/resume

After trying out Alan's method (which did work well), I installed the
drivers recommended by Wei and the problem seems to be resolved!

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

Status in linux package in Ubuntu:
Confirmed

Bug description:
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 suspend, in case that's relevant.

If I boot from power off, then the trackpad works fine in both the
pre-boot BIOS and in Ubuntu 22.04 (prerelease), including haptic
response to clicks. After a suspend/resume cycle, the trackpad stops
responding, although a lot of swiping/pressing will occasionally
produce a button press event. This state persists even if I reboot
out of Linux (without a power cycle) - for example the trackpad no
longer works for the pre-boot BIOS configuration screen, until a full
power cycle (which fixes the trackpad).

Possibly relevant, the trackpad seems to be this device to the kernel:
