I have laptop Asus K53SV and the touchpad was recognized as a mouse only. All of the features that it offered were just navigating the pointer, no scrolling, no disable when typing etc.

There is a patch available (elantech) which solves this issue and the touchpad is recognized with all (at least some 🙂 ) features.

First, install the dkms (Dynamic Kernel Module Support) package if it is not already installed on your machine:

sudo apt-get install dkms

Then, download the patch:

cd /usr/src/
sudo wget http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2

Unpack the patch:

sudo tar jxvf psmouse-elantech-v6.tar.bz2

Add the patch to the psmouse module:

sudo dkms add -m psmouse -v elantech-v6

Build it:

sudo dkms build -m psmouse -v elantech-v6

Install it:

sudo dkms install -m psmouse -v elantech-v6

For successful installation you should get something like this at the end: DKMS: install Completed.

Now, to load the new module with the patch included, you will need to either reboot your machine or reload the new module by executing the following command:

sudo rmmod psmouse && sudo modprobe psmouse

Now, go to System -> Preferences -> Mouse -> Touchpad and you will see all the settings that are available for the touchpad! 🙂
