Public bug reported:

I have a new installation of Ubuntu 11.10 on a Dell Inspiron 17r Laptop, and the
FN+F3 key combination does not work.

Expected: pressing Fn+f3 should disable the touchpad
Outcome: Although a transparent pop-up shows up on the top right hand corner
notifying user that the touchpad is disabled, the touchpad is still in operation.
Older distros had option under mouse/pointer device option disable touch pad
when typing, but this is not available with 11.10.
Fix: Making it operational Fn+F3, adding an option under mouse/pointing device to 
disable touchpad when typing, allowing configuration of Fn+F? keys
Relates to: ALPS driver, Synaptics, xorg config???

I tried many things to fix this problem: Installing Synoptics, defining custom key
combinations... unsuccessful

syndaemon -i 0.5 executed just fine.

gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled false
... this did not do anything. TouchPad works just fine, and it is not disabled even when I type (... and my chubby hands keep activating and clicking touchpad when I type). It might be because 11.10 distro does not have "/desktop/gnome/peripherals/touchpad/touchpad_enabled" and I don't know where else to find the device.

I did reinstalled xserver-xorg-input-synaptics package but it did not
help, neither installing xserver-xorg-input-synaptics-dev package helped

I saw xserver-xorg-input-synaptics:i386 package, but the synaptic
package manager was unable to install (dependencies etc).

This might be a clue: when I run
$ synclient -l
Couldn't find synaptics properties. No synaptics driver loaded?

obviouslly, some driver is loaded, since the trackpad works just fine,
except disabling it is a problem (I could not find what command fn+f3
calls), so it is a mystery as for what package is used.

system-> preferemces->Mouse and trackpad (via Unity) in 11.10 distro
does not even have the option of trackpad configuration.

here is the closest I got to the driver info:
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ImPS/2 ALPS GlidePoint 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)]

    ↳ Laptop_Integrated_Webcam_HD id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
