Reversing a Modprobe command

view story

http://ubuntuforums.org – Hello, I was having an issue with my laptop touchpad where my right click suddenly stopped woring. After some searching I discovered a solution but it broke some other touchpad functionality. These are the commands I used: Code: sudo su echo options psmouse proto=exps > /etc/modprobe.d/psmouse.modprobe reboot How can I reverse this? Thank you!! (Hardware)
