When I updated from 14.04 to 14.10 I noticed my track-pad cursor and left and right mouse clickers were not working. I have tried looking this issue up and can not find any solutions anywhere. If anyone could help me that would be amazing, I am using a wired mouse to my USB port for a temporary fix. I have a Dell Inspiron 15R.


In the terminal, type:

sudo vi /etc/modprobe.d/blacklist_i2c_hid.conf

then type the following into that file:

blacklist i2c_hid

Save the file and restart your system, now check whether the touchpad is working fine.
