My Acer Timeline has a "Disable touchpad button" which works too well. That is, once I've pressed it, pressing it again won't re-enable the touchpad. I've tried a couple of things like:
gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true
which worked once, but now when I do it again, it doesn't work again…
In fact, I'd like to know how to work out what the "disable touchpad" button is actually doing, and why doing it again isn't fixing the issue.

To disable touchpad:
To enable touchpad again:
and voila!
