+Subject: [PATCH libinput] evdev: disable ABS_MT_TOOL_PALM on the Lenovo X1
+ Carbon 6th gen
+
+This device randomly decides that a touch is now a palm, based on
+the moon phase, the user's starsign and possibly what the dog had for
+breakfast. Since libinput assumes that a touchpad that labels a touch as palm
+has reasons to do so, let's unassume this for this device by disabling that
+axis altogether and relying on the touch pressure only.
