Touchpad recognized as mouse - Multitouch gestures not working

[Santiago Persico]

I'm having a problem with my laptop, as the title says: The trackpad is being recognized as a mouse, so I don't have multitouch gestures, other than scrolling.

I can't switch apps with gestures, I can't change trackbar specific configurations, because, according to the System Settings panel, I've got a mouse, not a trackpad.

Not only that, but I had this same problem in Linux Mint and Ubuntu Mate 18.04, so I believe that it's not a distro-specific problem, so I don't know if this is the correct channel.

Initially the ticket was generated from Kubuntu 18.04 (the commands I've run are from that version, IRC), since then, I've updated to Kubuntu 20.10

I've tried following a couple of other guides to try to make the multitouch gestures work, but most are for previous kernel versions and are focused on just making the touchpad work, AFAIK.

My laptop is a Lenovo V330-15IKB.

Here's the System info according to the About tab in the System Settings app:

Operating System: Kubuntu 20.10
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.74.0
Qt Version: 5.14.2

I've opened the laptop, and took pictures of the insides, the ALPS chip says the following:

I've also uploaded the photos to Google Drive, there were some serial numbers and whatnot in them:

Tried this on ubuntu mate, didn't work. I think it only applies to non-working touchpads. Mine works, but it's recognized as a mouse, not as an actual touchpad.

> https://wiki.ubuntu.com/Multitouch/TouchpadSupport
Ubuntu doesn't include synclient any more, it seems, now it ships libinput.

> https://sangams.com.np/fix-ubuntu-18-4-touchpad-not-working-properly/
I tried installing "xserver-xorg-input-synaptics", couldn't, but I successfully installed "xserver-xorg-input-synaptics-hwe-18.04" (because all my other server-xorg packages look like have that name suffix).

The thing is, all the solutions I've found so far, only try to make the touchpad work, but the solutions so far, only go so far., not making it work **completely**.

I'm a noob at Linux, I come from windows, and over there, I had this working really well.
What should I do to make this work?. Thanks!
