Description Joachim Breitner 2018-02-16 15:17:24 UTC

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"
