Los cambios en el 50-synaptics.configarchivo no tienen ningún efecto. Me gustaría cambiar la resolución. Yo he añadido
Option "VertResolution" "20"
Option "HorizResolution" "20"
Consulte el archivo de registro. Quizás alguien pueda ayudarme a encontrar el problema. Los cambios se muestran en el /var/log/xorg.0.logarchivo, marcado con -->.
¿Por qué se sobrescriben?

¿Qué versión de Ubuntu estás ejecutando? Las últimas versiones de Ubuntu han reemplazado Xorg evdevcon Wayland usando libinput.
Como resultado, es posible que desee seguir los consejos proporcionados enhttps://askubuntu.com/a/864746/32664. Esa recomendación sugiere que realice modificaciones en la configuración del panel táctil a /usr/share/X11/xorg.conf.d/90-libinput.conf.
Nota:la solución proporcionada en ese enlace es para el 16.04. En mi propio equipo, estoy ejecutando Ubuntu GNOME 17.04 y ese mismo archivo conf se llama /usr/share/X11/xorg.conf.d/40-libinput.conf.
