[SOLVED] Can not configure touchpad "tap to click" in Mate-gtk3

gps1539 · 2016-11-01 23:24:12

I have gnome 3.22 and I just installed Mate-gtk3 1.16.1 desktop. Still running under GDM (testing Mate for now)

Mate works very well, except I can not figure out how to configure tap to click for the touchpad. Scrolling works fine, just not tap to click
I tried to enabled it via dconf-editor following the guide here https://wiki.archlinux.org/index.php/To … ptics#MATE and setting tap-to-click to true

gsettings get org.mate.peripherals-touchpad tap-to-click
true

Under gnome the touchpad "tap to click" works under wayland and xorg, so libinput seems to be correct.

This is on a Dell E7440 which uses a AlpsPS2 touchpad

I guess you are using xf86-input-libinput, as your touchpad driver, you need to create a config file for libinput at /etc/X11/xorg.conf.d/40-libinput.conf with something like below contents

# Match on all types of devices but tablet devices and joysticks
        Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
	Option "ScrollMethod" "twofinger"
	Option "Tapping"
EndSection

For more details read section on libinput at archwiki

Thanks for the reply
how does gnome on xorg work OK without such a conf file? does gnome get the config from somewhere else?

does this solve your issue?
Gnome may have ways to override the settings, I don't know as I don't use gnome.

Yes it did fixed the issue, thanks for the help.

My conf file.
cat /etc/X11/xorg.conf.d/30-touchpad.conf

Section "InputClass"
    Identifier "touchpad"
    Driver "libinput"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
    Option "Tapping" "on"
    Option "ScrollMethod" "twofinger"
    Option "TappingButtonMap" "lmr"
EndSection
