Ubuntu – ALPS touchpad on DELL Inspiron I15RN-3647BK with Ubuntu 11.10 x64


I can't make work the multitouch of the ALPS touchpad in my Dell Inspiron I15RN-3647BK with Ubuntu 11.10 x64, kernel 3.0.0-17-generic… I have tried with this driver but it doesn't work http://people.canonical.com/~sforshee/alps-touchpad/psmouse-alps-0.10/psmouse-alps-dkms_0.10_all.deb. This is the result from the following command:

user@laptop:~$ xinput list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ PS/2 Generic Mouse                        id=12   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Power Button                              id=8    [slave  keyboard (3)]
    ↳ Sleep Button                              id=9    [slave  keyboard (3)]
    ↳ Laptop_Integrated_Webcam_HD               id=10   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=11   [slave  keyboard (3)]
    ↳ Dell WMI hotkeys 

That came with or without the alps driver from canonical repository and the touchpad just works like a PS2 generic mouse…

Any ideas?

Thanks in advance…

Just didn't want to take credits for solving that problem. I did everything it said in that blog. Here's what I did in the terminal:

1. wget -O psmouse.tgz http://www.dahetral.com/public-download/psmouse-alps-dst-0.4.tbz/at_download/file
2. tar -xvf psmouse.tgz
3. cd usr/src/psmouse-alps-dst-0.4/src/
4. wget -O alps.c http://pastebin.com/raw.php?i=m404GW1G
5. cd ../..
6. sudo mv psmouse-alps-dst-0.4 /usr/src/
7. cd /usr/src/psmouse-alps-dst-0.4/
8. sudo dkms add psmouse/alps-dst-0.4
9. sudo dkms autoinstall
10. sudo rmmod psmouse && sudo modprobe psmouse
  • When I got to 10 it complained about psmouse module not existing so I did 9 again and just sudo modprobe psmouse and multitouch was already working. Then I rebooted and did 9 and 10 again because the touchpad had a lag and moved really slow. Don't know exatly what solved that but it's working great now.
