In some laptop models (e.g. [[HP/Pavilion/DV4\|HP Pavilion dv4]]), the touchpad deactivation toggle button works properly; in others (e.g. [[HP/G60\|HP G60]]), it seems to have no effect, even in the same version of Linux on a liveCD.
			==Solution==
			Tentatively, [http://vajiv.com/blog/disable-touchpad-in-linux-mint/ this solution] seems to be universal:
			* use <code>[[xinput]]</code> (seems to be installed by default) to get a device listing.
			* use <code>xinput list-props "{{arg\|name of touchpad device}}"</code> to verify that "Device Enabled" is set to "1".
			* use <code>xinput set-prop "{{arg\|name of touchpad device}}"</code> to deactivate the touchpad. (Works instantaneously; no reboot required.)

			Once you've verified that this works and you know what your device is named, it's simple to create a .sh file to turn off your touchpad and another one to turn it on.

==Notes==
In some laptop models (e.g. HP Pavilion dv4), the touchpad deactivation toggle button works properly; in others (e.g. HP G60), it seems to have no effect, even in the same version of Linux on a liveCD.

* <code>synclient TouchpadOff=1</code> to disable the touchpad (...<code>=0</code> to re-enable)
** Depending on how old your X server is you may have to add this to [[xorg.conf]]:
Section "InputDevice"
Identifier "synaptics"
Driver "synaptics"
Option "SHMConfig" "true"
EndSection

...or possibly:

Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Option "SHMConfig" "true"
EndSection

The X server may need to be restarted (i.e. reboot) after making changes. (The latter block is what worked for me.)

In theory, one can then use [[xbindkeys]] to assign a key to toggle activation of the touchpad -- where xbindkeys does apparently see the touchpad's deactivation button as a keystroke. (In practice, this also deactivated clicking from the external mouse. It's also not clear how to set xbindkeys to issue alternate commands so that toggling can be effected. Further experimentation is needed.)
