Yep, no multilib here, solved! You were right!

I am happy to hear this ! :D

... but I am sorry, I dont understand what you mean with "multilib". :(

This setting is necessary if you have an AMD NOTEBOOK and has no influence to a MULTILIB-system or a NO-MULTILIB-system. It doesnot matter which kind of system you have; only important is this kernel option.

In addition to others, I have to say that I have a Legion and I think it has the same touchpad and wiring. I can't explain why, but genkernel seems to be unable to produce an intramfs that is capable of bringing my touchpad up. I wondered why it worked with gentoo-kernel and noticed it used dracut. I decided to try it and it seems dracut does something genkernel does not, because since then I haven't had an issue with the touchpad.

If you use initramfs which I believe you should be as this is an UEFI boot, try dracut.

p.s. I can confirm pietinger's suggestion as unloading the designware platform module shuts down the touchpad and modprobing it again fixes it.

A little resurrection because I just got a lenovo.

This was (sort of) my solution. I use genkernel on gentoo-sources normally, but my touchpad wasn't working. There was another suggestion to use a distribution kernel gentoo-kernel-bin, which pulls in dracut and uses it. This worked. No idea why.

Not sure how to use dracut with gentoo-sources.
