With the latest HEAD of Linus, first I get: » Jun 10 12:19:17 cambrian kernel: psmouse serio1: synaptics: Your touchpad (PNP: LEN0072 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. Then if I patch drivers/input/mouse/synaptics.c and add "LEN0072" to smbus_pnp_ids, this strange thing happens: [ 8.526635] psmouse serio1: synaptics: queried max coordinates: x [..5676], y [..4760] [ 8.555746] psmouse serio1: synaptics: queried min coordinates: x [1266..], y [1094..] [ 8.555750] psmouse serio1: synaptics: Trying to set up SMBus access [ 8.615774] rmi4_f01 rmi4-00.fn01: found RMI device, manufacturer: Synaptics, product: TM3289-002, fw id: 2492434 [ 8.679863] input: Synaptics TM3289-002 as /devices/rmi4-00/input/input18 [ 8.682660] mousedev: PS/2 mouse device common for all mice … snipped … [ 107.225549] input: ImPS/2 Generic Wheel Mouse as /devices/rmi4-00/rmi4-00.fn03/serio2/input/input20 Notice how the trackpoint only appeared 100 seconds after boot (X was already started and initially the trackpoint was not listed in xinput) -- damjan -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
