Problema no Touchpad

[math10]

Olá pessoal, tenho um problema com o touchpad do meu notebook.

Ele funcionava perfeitamente no ubuntu 11.04, porém tive problemas e removi o 11.04 e instalei o ubuntu 10.10.

O corrento é funcionar assim:
http://www.ubuntudicas.com.br/blog/2010/11/ativando-rolagem-com-dois-dedos-e-circular-do-touchpad-no-ubuntu-10-10/

Lá em Sistema -> Preferências -> mouse -- existia a aba Touchpad onde funcionava a função touch.

Tentando deixar da mesma forma que funcionava na versão 11.04 eu executei os comandos:

$ sudo modprobe -r psmouse
$ sudo modprobe psmouse proto=imps

..depois disso a aba "touchpad" em preferências de mouse desapareceu. E não funciona mais o touchpad de jeito nenhum.
