I have a Lenovo thinkpad t510, with ubuntu 15.10.
When i first installed, I was able to use the middle click mouse button to copy and paste in the terminal. This button no longer does this, or anyother function evidently. I opened up
xev and tried clicking the middle mouse button. Nothing happened. I tried enabling and disabling the track pad. The same results.
I looked in the mouse configure section, under System -> Preferences -> Hardware -> mouse. I saw nothing about a middle mouse button.
I really liked the middle mouse button click copy and paste, how should I go about fixing this?
I am using Ubuntu Mate 15.10.
