Touchpad Multitouch does not work

Have you ever said to your wife that your mother cooked better? :man_shrugging:

" It was working on windows"


I’m so sorry, I said “it was working on windows” to indicate that my touchpad supports multitouch, and it’s not a hardware issue.
I hate windows and I will not use it again, I’m using Linux for 2 years since I know it.

It may not be so much the touchpad driver but the window manager or desktop environment support for gestures and the ways to configure them.

I found this:

libinput - ArchWiki

the whole article, but especially the section 3.5 and the following

Then there is the option to use the synaptics touchpad driver instead of libinput:

Touchpad Synaptics - ArchWiki

I rarely use my touchpad and never cared about gestures, so this is all just theoretical “knowledge”.

I read the whole article trying what is recommended, I found Synaptics is deprecated and not supported.
libinput working properly only with two fingers, so any gestures software (touchegg, fusuma, libinput-gesutres, etc.) does not receive any swipe signal

I already said that my “knowledge” is only theoretical.
again from the very start of this site

Touchpad Synaptics - ArchWiki

That’s not what it says.

It says (the red box)

Warning: xf86-input-synaptics is no longer actively updated. If possible, use libinput. For some reasons why you might still prefer xf86-input-synaptics, see, e.g. [1] and [2].

That, to me, is not the same as: depreciated and not supported

But then there is the blue box right below that red box:

Note: If you want to configure touchpad via GNOME Settings, you need to use the libinput driver.[3]

Which means (to me) that there is no point in using synaptics - not when you are on Gnome, that is.

I have no solution or informed and tested advice to offer. :man_shrugging:
