Comment # 43 on bug 1205410 from Takashi Iwai

That's the full of text, but there is no hardware detail information given yet.
So, let's start with that.

Could you upload the output of hwinfo from various kernels?  e.g. on Leap 15.4
and on 6.1-rcx.  Also, please give the dmesg outputs from both cases.

Then, try to check the touchpad device with evtest (included in the package
evtest).  Run it as root on a terminal, and you'll choose the device there.
Check the input device capabilities and whether the multi-finger tracking works
properly.
