Zoom on touchpad not working

[Baelor]

Hi there! It seems pinch to zoom is not working on my Zorin Core 17.2. Other gestures such as double-tap, swipe left-right with 3 fingers work without issues. Any ideas what might be wrong?

Interesting thread here:

Firefox pinch to zoom not working on 22.04

Are you running Zorin on Wayland or X11? The above thread mentions an issue with Wayland. I also wonder if it is anything to do with any apps you might have installed as Flatpak or Snap - these types of applications run outside the system, therefore gestures are likely not to work, as gestures are part of the system!

Ah, interesting!
Pinch-zoom works in Firefox for images, but not in Vivaldi. Vivaldi is installed as a flatpak, whereas Firefox is... not installed?!? I can open it and in the about window it says Firefox for Zorin OS 131.0 but I can not find it in the Software App under the installed apps.

Apparently (using this method linux - How to know whether Wayland or X11 is being used - Unix & Linux Stack Exchange ) I'm on Wayland. Do you recommend changing that to X11?

$ loginctl show-session 2 -p Type
Type=wayland

EDIT: Ok, logged in on X11 using the small cog down right in the login screen. On Vivaldi the pinch-zoom still does not work, but it does now at least for images in the viewer, but very shakily.

So, for my understanding: Is this a problem related to Wayland/X11 or to the driver of the touchpad? Any ideas how to improve this behaviour?

Well having read that thread I would do two things. Change to X11 and don't install flatpak apps.

Remove Vivaldi and get the .deb package from here:

Download Vivaldi | Vivaldi Browser

There is a down arrow to the right of the Windows download. You need the 64-bit .deb package. You should then be able to install via the software channel. If not install gdebi (Gnome deb installer):

sudo apt-get install gdebi

Open gdebi, then File, Open and point to where you have downloaded the vivaldi .deb file.

I tried your solution and it works, thanks! However the pinch to zoom is very imprecise and I found it more annoying than helpful, so in the end I ditched the approach.
But I stayed with X11 instead of Wayland, it seems that also other programs have missing functions under Wayland (KeepassXC does not offer autotype for example).
