Fix Synaptics Touchpad in Ubuntu 16.04

May 11, 2017

The touchpad in my Alienware 13 R2 used to work normally in Ubuntu 14.04 and 15.04, but it gets totally unresponsive when upgraded to Ubuntu 16.04. It seems this is a frequently-met problem on laptops that using Synaptics touchpad. After searching for solutions for a while, I found a solution from a dicussion thread in the Ubuntu bug report center:

Hi guys I found an solution:

Type in the terminal

sudo su
echo 'blacklist i2c_hid' >> /etc/modprobe.d/blacklist.conf
depmod -a
update-initramfs -u

and reboot

Hope did work for you!!

And this truely works for my laptop.
