This time, Lenovo decided to go with different pieces in its latest series
of Thinkpads.
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
