doing this does not make touchpad work

[kaye n <guikaye@gmail.com>]

Hello Friends!

This is my system:
Host: laptop Kernel: 4.19.0-6-amd64 x86_64 bits: 64 Desktop: Xfce 4.12.4
Distro: Debian GNU/Linux 10 (buster) 

From this web page, https://wiki.debian.org/SynapticsTouchpad
I tried this

$ mkdir -p /etc/X11/xorg.conf.d
$ echo 'Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "Tapping" "on"
EndSection' > /etc/X11/xorg.conf.d/40-libinput.conf
$ systemctl restart lightdm

It did not work. I guess it's to be expected since I'm using Debian 10 and not 9?

Any workaround?

Thank you very much!
