I assume the device in question is the 'SYNAPTICS Synaptics Large Touch Screen'. The log file in comment #56 shows that xserver-xorg-input-libinput is aware of the device but not using it.

It also looks like you have a Xorg config file that is trying to configure that device so that config file might be the problem. Please try removing any Xorg config files you have created.
