I installed touchpad-indicator to manage my touchpad settings while using an external USB mouse. Now, after some-time, my touchpad has stopped working after login to the Ubuntu system. It works fine till the login screen, then stops. I have tried removing and re-installing the touchpad-indicator application, but it doesn't help.
Can anyone please tell me the steps i need in order to evoke my touchpad again. I am using Ubuntu 11.10 with Kernel version 18.104.22.168 on a Lenovo G550 laptop.
