synclient -l | awk '/=/{printf "Option \"%s\" \"%s\"\n",$1,$3}'
synclient PalmDetect=1
OR
synclient SHMConfig=1
syndaemon -t -k -i 2 -d
synclient VertTwoFingerScroll=1
synclient HorizTwoFingerScroll=1

All those commands should go in your terminal. One at a time.
Note: Changes are temporary. 
To make it permanent, you should edit "50-synaptics.conf" file located in 
/usr/share/X11/xorg.conf.d/

sample :

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
# 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-to-ignore-configuration-errors.html
      MatchDevicePath "/dev/input/event*"
      Options "VertTwoFingerScroll" "1"
      Options "HorizTwoFingerScroll" "1"
EndSection
