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.
