I have installed Ubuntu 13.04 and I have opened Mouse & Touch-pad, but there is no Touch pad tap. I am using a Dell Inspiron 17R 7720 SE.

  • You should reinstall the driver for touchpad.

    1. First, delete your old dkms module, using terminal:

      cd /var/lib/dkms/psmouse/

      rm -rf alps-dst-0.4

    2. Download the new driver fom here.

    3. Install it, following next commands in terminal:

    tar xvf psmouse-alps-1.3-alt.tbz
    cp -afr usr/src/psmouse-alps-1.3/ /usr/src/
    dkms add psmouse/alps-1.3
    dkms autoinstall
    rmmod psmouse && modprobe psmouse
