Multitouch gestures on bluetooth trackpad

Hello, I am running Gnome on top of Arch Linux and having issues with multitouch gestures such as to finger scrolling. The Asus t300chi has a bluetooth keyboard/trackpad combo which is probably the issue.

I believe that linux treats the touchpad as a mouse, but gestures such as tap to click, and double tap to drag work.

Ive tried:
- Editing 50-synaptics.conf & 70-synaptics.conf
- Installing Touchegg and other alternatives

Here is the output of: xinput list. (Doesn't really look like it'd help)

⎡ Virtual core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
⎜   ↳ xwayland-touch:13                           id=8    [slave  pointer  (2)]
⎜   ↳ xwayland-pointer:13                         id=6    [slave  pointer  (2)]
⎣ Virtual core keyboard                       id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard                 id=5    [slave  keyboard (3)]
    ↳ xwayland-keyboard:13                        id=7    [slave  keyboard (3)]

Output for: libinput-list-devices: (Tap to click and Tap and drag work)

Device:           ASUS T300CHI DOCKING
Kernel:           /dev/input/event15

I am a newbie so please go easy on me, thanks in advance!

Re: Multitouch gestures on bluetooth trackpad

Welcome to Arch Linux.

My first question would be whether you are using Xorg or Wayland?  Gnome now defaults to the (IMHO not close to ready for prime time) Wayland.

Thanks, I believe that its using Wayland as seen in the output of 'xinput list'

Re: Multitouch gestures on bluetooth trackpad

What happens if you force Xorg over Wayland?   BTW, this is purely Socratic.  I use neither Gnome or Wayland.

Re: Multitouch gestures on bluetooth trackpad

What happens if you force Xorg over Wayland?   BTW, this is purely Socratic.  I use neither Gnome or Wayland.

For some reason, when I try to run 'Gnome Classic' or 'Gnome on Xorg' from GDM it just returns to the login screen.
I am not sure how to force Xorg instead of Wayland.

Edit: I managed to get into Gnome on Xorg through the console, there was an issue with some Xorg settings. Unfortunately changing to Xorg had no effect on my problem. Maybe some settings in Xorg would help?

Edit2: I edited 70-synaptics.conf following the wiki, no progress so far. Switching to Xorg fixed cursor grabbing issues on portal, which is nice.
