Ubuntu 21.10 no GPD Win Max 2021: touchpad clique/mantenha/arraste com o segundo dedo

Tenho um novo Win Max 2021 (edição Intel) do GPD. No Windows, conforme enviado, o touchpad permite que você aponte para algo, mantenha pressionado para clicar e arrastar e, em seguida, com um segundo dedo, arraste para o local desejado. No Ubuntu não consigo descobrir como ativar esse comportamento. ETA: de acordo com o driver do Windows, este é um dispositivo da “Goodix”, se isso ajudar.

Isto é o que eu recebo lsusb:

jtd@Volantis:~$ sudo lsusb

Ah, sim, conhecido fabricante de dispositivos "space space Mouse for Windows".

Não tenho certeza se a lsmodsaída é tão útil, mas:

Alguém tem alguma idéia de como fazer isso funcionar? Eu tentei o painel Configurações normais, gnome-tweaks e touche, e nenhum deles parece ter nada a ver com esse recurso.

Obrigado!
