Hello, When testing 4.12-rc6 on my HP EliteBook 8570w I noticed the following in my dmesg output: [ 10.377828] psmouse serio4: synaptics: queried max coordinates: x [..5648], y [..4806] [ 10.414770] psmouse serio4: synaptics: queried min coordinates: x [1292..], y [1048..] [ 10.414775] psmouse serio4: synaptics: Your touchpad (PNP: SYN019b SYN0100 SYN0002 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@xxxxxxxxxxxxxxx.
