Libinput 3 gestos com os dedos

Question

Como eu quero ter gestos de 3 dedos (ou até 4 dedos) rodando sob o Gnome (Fedora 25, Xorg), instalei os drivers de libinput e gestos de libinput ( link ).

Ao tentar depurar o motivo pelo qual os toques de três dedos não estão funcionando, percebi que libinput-gestures -r não mostra nada com mais de dois dedos.

Alguém tem uma ideia de como fazer isso funcionar?

O touchpad suporta multitoque com pelo menos três dedos (usei-o regularmente no Windows). Sistema que uso: Dell XPS 15 L501x

xinput-output:
