While trying to fix clickpad issues, I seem to have messed up my psmouse.conf. I attempted to follow the instructions here:
Right mouse button doesnt work
As mentioned by the answer on that post, the right-side detection was fixed, but full touchpad detection was broken and a number of more important features were broken such as scrolling. How can I restore /etc/modprobe.d/psmouse.conf to how it was on install, along with any additional files effected?
