Multi-touch no touchpad do Asus X551C (Ubuntu 12.04)

Question

Eu tenho um problema com a instalação do módulo psmouse elantech-x551c dkms no meu laptop Asus X551C com o Luna OS (construído no Ubuntu 12.04). Estou usando estas instruções link . Mas depois de executar o comando

sudo dkms ldtarball psmouse-elantech-x551c.tar.gz

i recebe um erro:

Error! psmouse-elantech-x551c is already added!
Aborting.

Se eu continuar com

sudo dkms install -m psmouse -v elantech-x551c

a saída é:

Preparação de kernel desnecessária para este kernel. Saltando ...

O comando

dkms status retorna:

psmouse, elantech-x551c: added
virtualbox, 4.1.12, 3.2.0-51-generic, x86_64: installed

Existe alguma sugestão que posso fazer? Preciso remover o módulo adicionado inicialmente? Se sim, então como posso fazer isso?

Atenciosamente
