Hello, after upgrading my kernel from 4.14.y to 4.19.y I was debugging some (non-input related) problems and also noticed this message from the synaptics driver: > psmouse serio2: synaptics: queried max coordinates: x [..5674], y [..4758] > psmouse serio2: synaptics: queried min coordinates: x [1268..], y [1096..] > psmouse serio2: synaptics: Your touchpad (PNP: SYN1218 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. > psmouse serio2: synaptics: Touchpad model: 1, fw: 8.2, id: 0x1e2b1, caps: 0xf00123/0x840300/0x26800/0x0, board id: 3189, fw id: > 1944273 > input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio2/input/input19 I proceeded by enabling I2C_HID and HID_RMI but still saw the message. After setting psmouse.synaptics_intertouch the message went away: > psmouse serio2: synaptics: queried max coordinates: x [..5674], y [..4758] > psmouse serio2: synaptics: queried min coordinates: x [1268..], y [1096..] > psmouse serio2: synaptics: Trying to set up SMBus access > rmi4_smbus 5-002c: registering SMbus-connected sensor > rmi4_f01 rmi4-00.fn01: found RMI device, manufacturer: Synaptics, product: TM3189-001, fw id: 1944273 > input: Synaptics TM3189-001 as /devices/rmi4-00/input/input20 So far I haven't noticed any problems with the touchpad. It's functioning like before. System is a XMG A506 notebook by Schenker, based on a Clevo barebone (N150RD IIRC). I've added the PNP id to smbus_pnp_ids[], so that I don't need the module option. With best wishes, Tobias
