For those we have been able to test: - the T480 is using Synaptics with an IBM trackpoint -> it behaves properly with or without intertouch, there is no point not using RMI4 - the X1 Carbon 6th gen is using Synaptics with an IBM trackpoint -> the touchpad doesn't behave properly under PS/2 so we have to switch it to RMI4 if we do not want to have disappointed users - the X280 is using Synaptics with an ALPS trackpoint -> the recent fixes in the trackpoint handling fixed it so upstream now works fine with or without RMI4, and there is no point not using RMI4 - the T480s is using an Elan touchpad, so that's a different story Signed-off-by: Benjamin Tissoires --- drivers/input/mouse/synaptics.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/input/mouse/synaptics.c b/drivers/input/mouse/synaptics.c index 60f2c463d1cc..14a1188561aa 100644 --- a/drivers/input/mouse/synaptics.c +++ b/drivers/input/mouse/synaptics.c @@ -173,6 +173,9 @@ static const char * const smbus_pnp_ids[] = { "LEN0046", /* X250 */ "LEN004a", /* W541 */ "LEN200f", /* T450s */ + "LEN0071", /* T480 */ + "LEN0092", /* X1 Carbon 6th gen */ + "LEN0097", /* X280 -> ALPS trackpoint */ NULL };
