Enable two-finger right click in GNOME with libinput

Synaptics automatically detected my touchpad as  a clickpad and interpreted a two-finger click as a right click. Libinput does not do this, though from what I have read it does support clickpads. Is there some way I can force it to reclassify the device as a clickpad and enable this setting?

You can do it in the Tweak Tool under Keyboard and Mouse > Touchpad > Click method

That only changes the click method, not enables two-finger-click!

I am having a similar issue as the OP, although libinput recognises single, two and even three finger tapping, I cannot seem to find a way how to change the mapping. Currently, two-finger-tap is set to the right mouse button and three-finger-tap is set to middle button and I would like to swap these two mappings...

Don't know if you're still having this problem, but I just switched over to libinput and had to figure this out. The relevant line in the 30-touchpad.conf is

Option ButtonMapping "1 3 2"

See https://wiki.archlinux.org/index.php/Li … re-mapping.

Re: Enable two-finger right click in GNOME with libinput

use xinput to get the id of your touchpad.
Then, use that id to get the properties using xinput --get-props
You can use that information and the --set-prop to change those properties.
You may also want to look at

Finally, you may want to investigate the --get-button-map and --set-button-map switches.
