touchpad no longer works
I am using Ubuntu 12.04 on a Compaq laptop. My touchpad suddenly stopped working on my user account. It works during login and it works for my guest account. I can use an external mouse. I installed "touchpad-indicator". It shows the touchpad as disabled but the enable command does not work. I entered the command:
gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true
This command did nothing. If anyone could help I would be very greatful.
