You can find this touchpads on DELL devices (I have it on my DELL Latitude e6430, but many other Laptops from DELL Vostro series have same device and also a bunch of HP Laptops are reported).
Anyway the problem with this touchpad is that is recognised as standard ps2 wheel mouse instead of synaptic/ALPS touchpad.. so you won't even find the touchpad tab under mouse settings and you get a stupid pad that is unable to scroll or tap to click (because it is seen as wheel mouse, so kernel does not understand gestures).
Check this in your mouse preferences, if you find just "mouse" tab and not "touhpad" and your touchpad is behaving like Neanderthal Man this can be a solution for you:
I found a way to fix this installing a custom 3rd party (but open) driver and using dkms.
download the latest driver source code package from here (currently newest package is 1.2):
http://www.dahetral.com/public-download
(really say thank you to these people who wrote this driver, God bless them)
put it in a folder of your choiche (eg: /home/youruser/alps-driver)
open a Terminal and cd to that folder
ten just run these commands (keep in mind that you have to be in the folder where you placed the file you just downloaded and to replace X.X with the version you downloaded.. at time of this writing is 1.2):
Code: Select all
sudo apt-get install dkms
tar -xf psmouse-alps-dst-X.X.tbz
sudo mv usr/src/psmouse-alps-dst-X.X/ /usr/src/psmouse-alps-dst-X.X/
sudo dkms add psmouse/alps-dst-X.X
sudo dkms autoinstall
sudo rmmod psmouse && sudo modprobe psmouse
I personally suggest Single Finger Scrolling ad Two Finger Scrolling behaves strange. But these are my 2 cents.
This driver will survive to the kernel updates because we installed it using dkms.
NOTE: if a new driver comes to the site I linked just download the new one and repeat the procedure.
For cleaniniess remove the old one with
Code: Select all
sudo dkms remove psmouse/alps-dst-X.X --all
Then you can also remove the relative folder in /usr/src.
Code: Select all
sudo rm -r /usr/src/psmouse-alps-dst-X.X
Enjoy!
