  1. This blog post contains instructions for installing patched mouse drivers, which enable correct recognition of your touchpad: http://nwoki.wordpress.com/2012/10/02/multitouch-fix-for-alps-touchpad/ Even this is a little outdated, as there have been several updates to the drivers since.

    In short: Download psmouse-alps-1.3: http://www.dahetral.com/public-download/psmouse-alps-1.3.tbz/view Then (using sudo / root):

    • Extract the folder psmouse-alps-1.3 to /usr/source
    • cd to /usr/source
    • dkms add psmouse-alps-1.3
    • dkms autoinstall
    • rmmod psmouse && modprobe psmouse

    Bam! Working multitouch! :-)

  2. If you want to enable your Dell Inspiron 15R Touchpad:

    • download that alps-dkms package and install it in /usr/src.
    • from a terminal, navigate to /usr/src/psmouse-alps-0.10/src and then gedit alps.c
    • in alps.c scroll down and copy the /* Dell Vostro 1400 */ line completely. In that line you will have to replace first 3 matches, that is , replace 0x73 , 0x02 , 0x50 with 0x73 , 0x03 , 0x50 .
    • Save the file and return to the terminal. In the terminal type dkms add -m psmouse -v alps-0.10
    • After this, type dkms build -m psmouse -v alps-0.10
    • after build is complete, install it with dkms install -m psmouse -v alps-0.10
    • after it installs it successfully, type rmmod psmouse && modprobe psmouse This will reload your psmouse module.
    • Next, type xinput --list to see whether it loaded successfully or not. If it shows Alps/PS2 Alps GlidePoint in the xinput , than congrats. And i bet it will show as i got it working by this! If you need complete patched module , you can ask me :)
