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

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
