Issues

No pressure-based touchpad found

Both Thinkpad X1 carbon Gen7 and Gen10 don't expose pressure to libinput:

$ sudo libinput measure touchpad-pressure
Using SYNA8016:00 06CB:CEB3 Touchpad: /dev/input/event5
This device does not have the capabilities for pressure-based touch detection.
Details: Device does not have ABS_PRESSURE or ABS_MT_PRESSURE

sudo libinput measure touch-size
Using Raydium Corporation Raydium Touch System: /dev/input/event4
This device does not have the capabilities for size-based touch detection.
Details: Device does not have ABS_MT_TOUCH_MAJOR

So there seems to be no way of calibrating the pressure thresholds. See this comment:

looks like this touchpad doesn't have either pressure or size so any pressure handling is done by the firmware. In that case there's not much we can do since libinput doesn't get any data to tell it when a finger has too light pressure to be considered that. This bug looks like a kernel issue and it cannot be fixed in libinput directly. I'm closing this bug but do feel free to continue discussing the issue here. Kernel bugs are usually best sent to the linux-input list.
