Enable circular scrolling

I'm trying to enable circular scrolling in my touchpad with synaptics, but something is preventing me of doing so. My 50-synaptics.conf looks like this:

Section "InputClass"
    Identifier "touchpad catchall"
    Driver "synaptics"
    MatchIsTouchpad "on"
    Option "TouchpadOff" "0"
    Option "TapButton1" "1"
    Option "TapButton2" "2"
    Option "TapButton3" "3"
    Option "VertEdgeScroll" "off"
    Option "VertTwoFingerScroll" "on"
    Option "CircularScrolling" "on"
    Option "CircScrollTrigger" "0"
    Option "HorizEdgeScroll" "off"
    Option "HorizTwoFingerScroll" "on"
    Option "VertScrollDelta" "-108"
    Option "HorizScrollDelta" "-108"
EndSection

I've tried Idea the vert/horiz scrolling lines out, but didn't work.
How can I make it work? Because the Arch wiki says it's correct.
