Put this into
$ sudo gedit /etc/X11/xorg.conf

Section "InputDevice"
    Identifier     "Arc"
    Driver         "mouse"
    Option         "CorePointer"
    Option         "Device" "/dev/input/mice"
    Option         "Protocol" "ExplorerPS/2"
  # Option         "Emulate3Buttons" "true"
    Option         "VertScrollDelta" "3"
EndSection

Then do

$ sudo /etc/init.d/gdm restart

to restart the xserver.

The fault happens because the arc saves settings in the mouse!!
See if that works
