Mapeamento do mouse Lenovo N700

Question

Eu tenho um Lenovo Mice N700, que foi construído para Windows 8. Ele funciona perfeitamente no Ubuntu (16.04), mas tem 2 falhas: deslizar.

No Windows 8, eles deveriam acionar ações como deslizar as bordas da tela sensível ao toque/touchpad. O problema é que ele é mapeado para teclas Ce Backspace(com uma ordem estranha de modificadores enviados). Eu gostaria de remapear para Alt + Left Arrowe Alt + Right Arrow. Isso seria possível?

Aqui está a saída do xev:
