I have Debian Stretch (xfce) and my touchpad doesn't react to tap.

I searched some solutions to fix it, example:

  • create 50-synaptics.conf to /etc/X11/Xsession.d/ and /usr/share/X11/xorg.conf.d/


Section “InputClass”
        Identifier  “touchpad catchall”
        Driver  “synaptics”
        MatchIsTouchpad “on”
MatchDevicePath “/dev/input/event*”
        Option  “TapButton1”  “1”
        Option  “TapButton2”  “2”
        Option  “TapButton3”  “3”

But If I try something solution, I every get crash with starting Light-Display-Manager.

I have to delete 50-synaptics.conf and reboot notebook.

So can I fix my problem with touchpad?

  • Have you tried renaming the file to just synaptics.conf? Also, are you able to try configuration through synclient? It should be installed alongside synaptics. Feb 3 '18 at 2:35

Debian 9 "Stretch" is using libinput driver

$ 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
