From Terminal run xinput to discover the mouse device name

⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Microsoft Microsoft® Classic IntelliMouse®        id=10   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]

Run xinput get-button-map with the mouse device name to output the mouse button map. The first three digits (1 2 3) of the map represent the left, middle, and right mouse buttons. Setting the digit in position 2 to zero disables the mouse middle or wheel click button.

xinput get-button-map "Microsoft Microsoft® Classic IntelliMouse®"

1 0 3 4 5 6 7

From Terminal run xinput as follows to disable middle button for the current session

xinput set-button-map "Microsoft Microsoft® Classic IntelliMouse®" 1 0 3 4 5 6 7

For a permanent solution create a desktop file, e.g. “mousewheelpasteoff.desktop” with the contents below and save it to ~/.config/autostart folder. This script will run at login to disable the wheel click button.
