My touchpad seems to be recognized as a mouse instead of a touchpad. I have a Dell Precision M4600, and I am running Ubuntu 11.04 64-bit.

vegard@vegard-laptop:~$ xinput list
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Logitech USB Receiver                     id=12   [slave  pointer  (2)]
⎜   ↳ ImPS/2 ALPS GlidePoint                    id=14   [slave  pointer  (2)]
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]

    ↳ Power Button                              id=8    [slave  keyboard (3)]
    ↳ Sleep Button                              id=9    [slave  keyboard (3)]
    ↳ Laptop_Integrated_Webcam_FHD              id=10   [slave  keyboard (3)]
    ↳ Logitech USB Receiver                     id=11   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]
    ↳ Dell WMI hotkeys                          id=15   [slave  keyboard (3)]

Even though it seems to detected properly, I do not have any Touchpad settings available in Mouse Preferences.

My problem, specifically, is that my clumsy hands touch the touchpad while I am typing, send errant clicks my way, and I'd like to disable the touchpad while typing.

I suppose GNOME's disable while typing option doesn't work then? – htorque Jun 25 '11 at 11:38
@htorque It is simply not present in Mouse Preferences. If it was there, I'd use it. – Vegard Larsen Jun 25 '11 at 11:41

Download psmouse-alps-1.3: Then (using sudo / root):

Extract the folder psmouse-alps-1.3 to /usr/source
cd to /usr/source
dkms add psmouse-alps-1.3
dkms autoinstall
rmmod psmouse && modprobe psmouse

Bam! Working multitouch! :-)

This seems to be a known bug with those ALPS touchpads (ImPS/2 ALPS GlidePoint is the entry for your touchpad).

This is a good explanation for why it does not work. However, I am interested in a more permanent fix besides patching drivers and compiling it myself. – Vegard Larsen Jun 25 '11 at 11:52
The more permanent fix would be to wait for a kernel update for 11.04. However, I can't say how likely that will happen as it depends on the complexity/regression potential of the actual patch/fix if it gets backported or not. – htorque Jun 25 '11 at 13:48
