How do I enable multi touch on a Dell inspiron n5110 with an ALPS touchpad?

How can I enable touch pad gestures(multi touch effects) of alps touch pad which comes with dell inspiron n5110 in ubuntu 11.10. These gestures worked fine with windows.

Solution 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of your touchpad: http://nwoki.wordpress.com/2012/10/02/multitouch-fix-for-alps-touchpad/ Even this is a little outdated, as there have been several updates to the drivers since.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! :-)
