[    9.898459] psmouse serio1: synaptics: Your touchpad (PNP: LEN008e PNP0f13) says \
it can support a different bus. If i2c-hid and hid-rmi are not used, you might want \
to try setting psmouse.synaptics_intertouch to 1 and report this to \
linux-input@vger.kernel.org.

So I'm reporting. Tested this option on my Lenovo ThinkPad T25, everything works \
perfectly.

My friend with Lenovo ThinkPad T480 tested this option too:

He reported that his machine works fine as well.
