I have a DELL Inspiron 17R SE 7720 Laptop and the Alps touchpad is not detected as a touchpad. I tried the psmouse-alps-dst-1.0.tbz and the touchpad is detected but the pointer movement is. The linux kernel (as of 3.13) does not recognize them as an ALPS touchpad, and they end up being recognized only as a PS/2 mouse. For this reason there is no scrolling, no middle button emulation, no two finger recognition, etc. The Linux driver implementer’s API guide. Currently the ALPS touchpad driver supports seven protocol versions in use by ALPS touchpads, called versions 1, 2, 3. Fixing my Alps Touchpad with the Synaptics Driver November 15, 2005 Posted by Carthik in guides, ubuntu. Ever since I upgraded to Breezy, the touchpad on my laptop has been acting funky. Brief update to installing the ALPS driver set. I followed the below instructions but found the driver was now at this location. As users will note this is now version 0.11 of the ALPS driver and the line to remove in this version is line 137.

This HowTo is about getting ALPS touchpad to work under debian (tested on sid) using a 3rd party driver and dkms.
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):

(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

now you'll find the TouchPad tab under mouse settings and you can enable scrolling and tapping. just because now is considered a touchpad and not a PS wheel mouse.

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

where X.X is the number of the old version to remove from dkms.
Then you can also remove the relative folder in /usr/src.

Code: Select all

sudo rm -r /usr/src/psmouse-alps-dst-X.X

hope this helps.
Enjoy!

Linux kernel driver for newer ALPS touchpads (as of Mar 2014)

QUICK START

📢 Make sure you have dkms and linux-headers installed in your system: 📢

Run the following commands in your shell as root:

This will build and install the updated psmouse module for your current kernel.

INTRODUCTION

Some new machines, like the Lenovo Ideapad Flex 15 have a new ALPS touchpadwhich uses a protocol different from previous versions. The linux kernel (as of3.13) does not recognize them as an ALPS touchpad, and they end up beingrecognized only as a PS/2 mouse. For this reason there is no scrolling, nomiddle button emulation, no two finger recognition, etc.

Hp pavilion dv6000 recovery disk windows vista 32 bits. The folks at the linux kernel input devices mailing list were very helpful andpointed me to the right patches, I have simply gathered them together and addeda dkms.conf file to make it easier to build. This page(https://github.com/he1per/psmouse-dkms-alpsv7) explains how you installand build the module.

Thanks specially to Tommy Will from the linux-input@vger.kernel.org mailing listand to Elaine (Qiting) who actually wrote the code :) The original patch fromElaine is found here:

DO I NEED THIS MODULE?

If you get an error like this from dmesg:

then you need this module. Your touchpad will be recognized after you install it.

If you have a Toshiba Z30-A, you need to update to kernel 3.17 and you won'tneed this patch.

BUILDING and INSTALLING

Pre-requisites:

• dkms:

• linux headers will be installed as a dependency if you use anyof the commands above.

Manual build and install of psmouse.ko

It is better to use install.sh, but if you want to build and installmanually you can follow these instructions.

As root do the following from the directory where this README is found:(all this is done automatically by the install.sh script)
