I have a Toshiba Satellite C55 which is configured as a dual boot (Windows 8/ Ubuntu 12.04 LTS)

Recently I connected a USB mouse and since the touch pad on the laptop has stopped working with or with out the USB mouse. The two buttons are working. I have referenced a following post but have not been able to find a solution.

Any help is greatly appreciated.



Try the following

sudo apt-get install xserver-xorg-input-synaptics

synclient TouchpadOff=0

sudo chmod +wrx '/var/lib/dpkg/lock'

sudo apt-get install synaptic
