Край, прокручивающий, хорошо работает, но два пальца, прокручивающие, прекратили работать?

После переустановки Xorg мои два пальца, прокручивающие сенсорной панели, прекратили работать, хотя край, прокручивающий, работает отлично. Я попробовал различные решения, но ни один из них не работает.

Мой оригинал/etc/X11/xorg.conf.d/50-synaptics.conf файл

# Example xorg.conf.d snippet that assigns the touchpad driver
# to all touchpads. See xorg.conf.d(5) for more information on
# InputClass.
# DO NOT EDIT THIS FILE, your distribution will likely overwrite
# it when updating. Copy (and rename) this file into
# /etc/X11/xorg.conf.d first.
# Additional options may be added in the form of

#
Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
# This option is recommend on all Linux systems using evdev, but cannot be
# enabled by default. See the following link for details:
# http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html
      MatchDevicePath "/dev/input/event*"
EndSection

Section "InputClass"
        Identifier "touchpad ignore duplicates"
        MatchIsTouchpad "on"
        MatchOS "Linux"
        MatchDevicePath "/dev/input/mouse*"
        Option "Ignore" "on"
EndSection

Я выполнил следующую модификацию, как предложено в различных местах, но все еще проблема сохраняется.

Мой Xorg.0.log похож на это.
