Botões do touchpad Dell Inspiron 1520 não detectados no Ubuntu 14.04

Question

Eu instalei recentemente o Ubuntu 14.04 no meu laptop Dell Inspiron 1520. Após a instalação, o touchpad foi detectado, mas Vertical & amp; Rolagem horizontal e Esquerda e & amp; Clique com o botão direito do mouse não estava funcionando. Então eu ajustei a configuração do synclient usando o comando

synclient -l 

e descobri que a funcionalidade de rolagem estava desativada, então ativada. Eu tentei muito, mas não consegui encontrar uma maneira de ativar os botões de clique direito e esquerdo. O touchpad do meu laptop é o mesmo da imagem na url.

sem garantia, mas cavando na net, seu problema parece estar relacionado ao xorg.conf

Eu tentarei isso:

sudo apt-get install xserver-xorg-input-synaptics

sudo gedit /etc/X11/xorg.conf

adicione:

# Modules section. This allows modules to be specified
# **********************************************************************

Section "Module"
       Load  "synaptics"

, em seguida, reinicie o X (esse último comando o levará para o login gdm, então salve o que você está fazendo antes!):

sudo restart lightdm

Deixe-me saber se funciona:)
