synPS/2 Synaptics TouchPad not working, libinput / synaptics driver

Hello community. Having problems with the touchpad on my Satellite C55D Laptop.

Kernel release:  4.12.13-1-ARCH

I am using Gnome as the UI and boot straight into it.

My /etc/X11/xorg.conf contains only 00-keyboard.conf and 40-libinput.conf.

output of

/etc/X11/xorg.conf/40-libinput-conf

    ↳ xwayland-keyboard:13                    	id=8	[slave  keyboard (3)]

Based on what I have read I think a problem is line 99.880 and the few lines above where several classes are applied. I previously had the synaptics driver but removed it - there isn't a synaptics file in /usr/share/X11/xorg.conf.d. Also I thought it should show up in the output of 'xinput' although my mouse doesn't and that works fine.

Any advice would be greatly appreciated.

Re: synPS/2 Synaptics TouchPad not working, libinput / synaptics driver

Are you running Gnome on Wayland or Gnome on X?

No, it didn't "fix" anything. It just shifted the brokeness one space to the right. - jasonwryan
