arch linux, gnome-3.20 and xf86-input-synaptics

I am running arch linux with gnome desktop on a Lenovo Thinpad X230. Some time ago gnome 3.20 was released and apparently the synaptics driver is not supported any more.

The only reason I ran into this was because “tap to click” was turned on all of sudden and it interfered with my typing.

Initially, I heeded the advice on the synaptics wiki page: “Synaptics is no longer supported under GNOME. Migrate to libinput.” but the libinput driver was intolerably slow on my system even though I cranked the touchpad speed up to the max.

Anyway, I went back to the synaptics driver and disabled the irritating “tap to click” behaviour by setting the following values in /usr/share/X11/xorg.conf.d/50-synaptics.conf:

Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
Option "TapButton1" "0"
Option "TapButton2" "0"
Option "TapButton3" "0"

I hope this helps 🙂
