Não consigo alterar a resolução vertical / horizontal do meu touchpad

0

Alterei as configurações no arquivo 50-synaptics.conf , conforme indicado neste encadeamento: Alterar a aceleração / sensibilidade horizontal e vertical do touchpad?

Eu adicionei:

Option "VertResolution" "75"
Option "HorizResolution" "75"

Já tentei números diferentes, mas isso não parece mudar nada para mim. Talvez não esteja usando o driver synaptics? Usando um Lenovo U31-70 e 16.04 LTS

EDIT: conforme solicitado Saída de xinput :
