Hello, hope all of you are well in 2020.
This is my first bug report so be gentle. I have searched for previous tickets and I feel this one is different enough to warrant a separate ticket.

From searching issues on other Ideapads/Thinkpads etc I understand my touchpad is likely made by Elantech. In my case however, I have no reference to elan at all in any logs I search. Nearly all forum posts find at least something, I do not, which is what has prompted me to post here.

[url=https://bugs.archlinux.org/task/59714]This thread[url] is a couple of years old but has a new comment from last month describing a touchpad issue, with output from the commands. I get nothing:
[code]
$ ls .local/share/xorg/Xorg.0.log | grep -i touchpad
$ journalctl -k | grep elan

Snippet of my /etc/default/grub. Commented lines are past attempts.

I have tried adding these params from this thread: https://bbs.archlinux.org/viewtopic.php?id=248740
[code]
$ cat /etc/modprobe.d/elan.conf

If xinput finds a virtual pointer, does that mean it exists or is it a default value? This is the only thing I have some semblance of hope in that says the hardware works.
[code]
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ USB Optical Mouse id=10 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Power Button id=9 [slave keyboard (3)]
↳ Integrated Camera: Integrated C id=11 [slave keyboard (3)]

It's worth noting I have only serio0, no serio1 as I have seen in other threads.
[code]
$ cat /sys/bus/serio/devices/serio0/firmware_id

$ cat /sys/bus/serio/devices/serio0/description

The output of "cat /proc/bus/input/devices" is in the attached file.

I am thinking either using a bad kernel version, the hardware is knackered, or the software is just not ready yet as the laptop is quite new. A few friends are telling me to try and see if it works in Windows, but an optical mouse works for now and this is a challenge to beat!
