Touchpad click not working in xfce4

[Debian]

I am using xfce4 in linux-mint. Touchpad click is not working while I can scroll using 2 fingers and left-right click are also working. Contents of file

Code: Select all

/usr/share/X11/xorg.conf.d/50-synaptics.conf 

are:

Code: Select all

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        Option "TapButton1" "1"
        Option "VertEdgeScroll" "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-to-ignore-configuration-
    errors.html

      MatchDevicePath "/dev/input/event*"
    EndSection

When I run

Code: Select all

synclient TapButton=1

command I get error:

Code: Select all

Couldn't find synaptics properties. No synaptics driver loaded?

and output of

Code: Select all

xinput -list  

is:

Code: Select all

 Virtual core pointer                    	id=2	[master pointer  
    (3)]
    ⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  
    pointer  (2)]
    ⎜   ↳ Logitech USB Receiver                   	id=11	[slave  
    pointer  (2)]
    ⎜   ↳ ETPS/2 Elantech Touchpad                	id=15	[slave  
    pointer  (2)]

So it is using

Code: Select all

Elantech driver

instead of synaptics driver, should I change the driver? If not then how to fix the issue?
