circular scrolling not working well

Dell Latittude E5530 again.  I added lines to /etc/X11/xorg.conf.d/50-synaptics.conf

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "TapButton2" "2"
        Option "TapButton3" "3"
        Option "VertEdgeScroll" "1"
    Option      "CircularScrolling"          "on"
    Option      "CircScrollTrigger"          "0"
#    Option      "CircScrollDelta"          "0.1"
# This option is recommend on all Linux systems using evdev, but cannot be
# enabled by default. See the following link for details:
# http://who-t.blogspot.com/2010/11/how-t … rrors.html
        MatchDevicePath "/dev/input/event*"
EndSection

and circular scrolling technically works.  But to actually have it stay circular, I need to trace my fingers around the center of the touchpad.  On this laptop, under Ubuntu and using glidepoint drivers, I was able to keep circular scrolling with almost any circular motion, e.g. a circle in the upper right quadrant of the pad.  If I try that now, it just scrolls up and down, reversing itself.  How can I fix or configure this?

I tried gpointing-device-settings too, but changing the start point either didn't help or actively broke.  Also the program says
"An X error occurred. The error was BadAtom (invalid Atom parameter).
An X error occurred. The error was BadAtom (invalid Atom parameter)."
at startup, FWIW.

It's probably the "VertEdgeScroll" option interferring with the circular scrolling --- try setting it to "0"

Okay, I'll try that.
Is there any way of doing so without restarting my whole X session?  Sending a kill signal of some kind to Xorg, say?

Re: circular scrolling not working well

synclient vertedgescroll=0

EDIT: this will not persist across re-boots, change the .conf file if it works

Ah, a useful thing to explore, thanks!  Didn't solve my problem,though.
