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

[Roland Dreier]

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:

and the last kernel messages before suspend are:

This change was made by a bot.

[Ryan MacLellan (ryanmac)]

Same system, same symptoms.

[Gamithra M (starkblast)]

Same issue here, same machine. I'm dual booting and the issue persists on Windows, too, even in BIOS settings.

[Wei (hhwei)]

Same machine and same issues here. works fine in Windows.

[Simon Heß (tartax)]

Same problem on the same machine on ubuntu-derived Pop!_OS 21.10. Also persists in Windows after reboot. Problem is temporarily fixable by switching the trackpad off in bios, saving, and switching it on again.

[Wei (hhwei)]

I found this issue fixed after a Senel firmware update (v0.22.520, 28 Mar 2022): https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x1-titanium-type-20qa-20qb/downloads/driver-list/component?name=Mouse,%20Touchpad,%20Keyboard%20and%20Pen
The update is applied in windows.

[Alan Ferrier (alanferrier)]

The firmware update suggested by Wei above didn't resolve the issue for me, I'm afraid. Still need a full power cycle to return to trackpad functionality after a suspend/resume.

[Alan Ferrier (alanferrier)]

An interesting observation - if I suspend the laptop via the keyboard shortcut or suspend menu *before* closing the laptop, it appears to mitigate the issue - the trackpad still works when I re-open the lid. Dunno if this is helpful - it's non-optimal but better than a power-cycle.

[Wei (hhwei)]

I shall confirm that after the fix mentioned above, my trackpad has been working very well.
I think that is a software issue.
I have some suggestions to try:
- verify if this issue happens also in windows?
- try update all drivers using the tools provided by Lenovo
- maybe update BIOS
- in Windows, there is the Senel driver software, launch it, see their menu, look for something that may make a change
- stay in Windows for it to automatically update
- update Ubuntu (which I think you must have already did), I am using 20.04

[Gamithra M (starkblast)]

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

[Alan Ferrier (alanferrier)]

I can confirm that after installing ALL Windows 10 updates, recommended and optional AND all updates using the bundled "Lenovo Commercial Vantage" application (which also updated the BIOS) it does indeed appear that this issue is resolved.

Thanks to Wei and Gamithra for their suggestions and assistance.

[Alan Ferrier (alanferrier)]

As an added bonus, I'm fairly sure the driver updates have significantly improved my battery life, so two thumbs-up.

[Roland Dreier (roland.dreier)]

Is there any way to perform these updates without Windows? I overwrote the whole drive when I obtained Ubuntu. I have performed a few BIOS / EC updates via fwupdmgr, but the system shows as up-to-date now.

[Alan Ferrier (alanferrier)]

Lenovo appears to provide all the software and drivers with both Windows and Linux utilities to install them here: https://pcsupport.lenovo.com/gb/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x1-titanium-type-20qa-20qb/downloads/driver-list/

You probably have to install them one-at-a-time, which is a bit of a PITA.

[Roland Dreier (roland.dreier)]

I don't see Linux versions of the touchpad firmware?

[Wei (hhwei)]

I am pretty sure ``the Sensel Forcepad Device Firmware'' does not available outside Windows, at least they are not listed on the support page posted by Alan.

I suggest you can set up a dual boot and install Windows. It is likely windows will be automatically activated. I guess many firmware updates might only be available in windows.
