Estou com esse mesmo problema em partes. Instalei o ubuntu 15.10. Comprei um mouse sem fio MultiLaser e não consigo editar a sensibilidade do mesmo. Na opção Mouse e TouchPad do ubuntu, só é possível regular do TouchPad. Não apresenta uma opção para o mouse.
No meu caso, dando um xinput list no terminal, ele retorna o seguinte resultado:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SYN1B7E:01 06CB:2970 UNKNOWN id=11 [slave pointer (2)]
⎜ ↳ Telink Wireless Receiver id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ HD WebCam id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
↳ Acer WMI hotkeys id=13 [slave keyboard (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SYN1B7E:01 06CB:2970 UNKNOWN id=11 [slave pointer (2)]
⎜ ↳ Telink Wireless Receiver id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Sleep Button id=8 [slave keyboard (3)]
↳ HD WebCam id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
↳ Acer WMI hotkeys id=13 [slave keyboard (3)]
De acordo com esse resultado, podemos verificar que está faltando a sequência 1 e 9. Assim sendo executei xinput list-props 1: unable to find device 1
E o xinput list-props 9 que retornou o seguinte:

Por se tratar de um mouse sem fio, parece que essas configurações tratam-se apenas do receptor de sinal e não do mouse.
De todo modo, instalei o dconf-tools e fui no caminho (org -> gnome -> settings-daemon -> peripherals -> mouse) conforme orientado. Porém a opção motion-acceleration não existe. Tendo apenas as: double-click, drag-threshold e locate-pointer.
Agradeço se alguém puder ajudar o/
