On Rhino Linux with GNOME 46.2 this was set to true when I found it, I toggled it, etc., but it still allows touchpad input regardless of true/false setting.
I’m not sure I can continue to use this install if I can’t figure out how to enforce a true setting.

I’ve tried removing xserver-xorg-input-synaptics and after a reboot the touchpad works on the login screen, but once I log in, the touchpad is not recognized.
I think at this point, maybe what I’m looking for is how to replace the synaptics (which was not installed on ubuntu 22.04) with libinput.
$ dpkg --list |grep xserver-xorg-input
ii xserver-xorg-input-all 1:7.7+23ubuntu3 amd64 X.Org X server -- input driver metapackage
ii xserver-xorg-input-libinput 1.4.0-1build1 amd64 X.Org X server -- libinput input driver
ii xserver-xorg-input-multitouch 1.0~rc3-2.1 amd64 Multitouch X input driver
ii xserver-xorg-input-synaptics 1.9.2-1ubuntu3 amd64 Synaptics TouchPad driver for X.Org server
ii xserver-xorg-input-wacom 1:1.2.0-1ubuntu2 amd64 X.Org X server -- Wacom input driver
file a bug with libinput please, this is almost always an issue with the touchpad not being detected as internal touchpad and thus not being paired with the keyboard.
I’m not entirely sure what happened between the installation of the custom Rhino XFCE desktop (“Unicorn”) and when I posted that, but something decided to install the synaptics driver and it was not clear how to get rid of it.
I don’t really know that I would file this against libinput since I don’t really think it is at fault here. What I did end up doing was just move everything from Ubuntu 22.04 to the Rhino directory, then I removed the 10-amdgpu.conf and 10-radeon.conf as well since I’m using an embedded Intel GPU.
After restarting the display manager, this change solved the problem.

The as-found non-working Rhino /usr/share/X11/xorg.conf.d/ was moved to /usr/share/X11/xorg.conf.d/~backup~.
The as-found was-working Ubuntu 22.04 (mounted at /mnt/p9) /usr/share/X11/xorg.conf.d was copied to the analogous Rhino dir and then, after inspection the previously mentioned 10- files were also removed since this laptop’s not seeing another GPU.
As you can see, there’s no difference in the remaining files (or the 10- files that were removed). I don’t know if I need the wacom driver or not for the touch screen, but thankfully that’s still working.
Anyway, long story short, this might be an option if someone else finds this, but I don’t see how libinput is at fault since all I had to do was remove the synaptics files. It would seem to me that whatever put/left the synaptics file there is what is at fault. I have no idea if that’s Rhino, XFCE, GNOME, or the FSM.
