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...
