I used touchpad-indicator to disable the touch-pad in Ubuntu 11.04.
Now I update to Ubuntu 11.10, and I installed touchpad-indicator in ubuntu 11.10 again but I can not enable the touch-pad.
When I press the shortcut set in ubuntu 11.04, it says "Error while trying to run
(/usr/share/touchpad-indicator/change_touchpad_state.py)" , and I search in that dir and find out there's no that file(change_touchpad_state.py).
I'm thinking maybe this is because the new version touchpad-indicator(0.9) works in a different way.
So how can I enable my touch-pad without installing ubuntu 11.04 and enable it on and then switch to 11.10 again ?
