Disabling Trackpoint Scrolling via xorg.conf freezes screen/input

Description
I have upgraded xserver-xorg-core and xserver-xorg-legacy from 2:1.19.5-1 to 2:1.19.6-1. When I rebooted, the system (a T460s Thinkpad) would start, but as soon as the X server is started, the screen would turn black and no input would be accepted -- not even switching to the text terminal.
The problem disappeared once I removed the file /etc/X11/xorg.conf.d/30-scoll.conf with this content:
Section "InputClass" Identifier "TPPS/2 IBM TrackPoint" Driver "libinput" Option "ScrollMethod" "none" EndSection
I have added the corresponding xorg log to the list of log files below, note how it stops abruptly at
[ 187.857] (II) event9 - (II) Integrated Camera: Integrated C: (II) is tagged by udev as: Keyboard [ 187.857] (II) event9 - (II) Integrated Camera: Integrated C: (II) device is a keyboard [ 187.858] (II) config/udev: Adding input device (unnamed) (/dev/ttyS0) [ 187.858] () (unnamed): Applying InputClass "TPPS/2 IBM TrackPoint" [ 187.858] (II) Using input driver 'libinput' for '(unnamed)' [ 187.858] () (unnamed): always reports core events [ 187.858] () Option "Device" "/dev/ttyS0" [ 187.858] () Option "_source" "server/udev"
