Natural scrolling Ubuntu mouse logitech T620 and others

Ho avuto un paio di problemi con il natural scrolling del mouse della Logitech T620 e Ubuntu Gnome Shell
Diciamo che l’applicazione per la configurazione del mouse non funziona molto bene: l’attivazione o la disattivazione del natural scrolling non si ripercuote ne nel touchpad ne nel mouse
Così ho trovato questa bellissima risposta su Ask Ubuntu
A questo punto devo disabilitare sul mouse il natural scrolling.

1. lista degli xinput
2. identificare il mouse
3. lista delle proprietà del mouse

4. disabilitare il natural scrolling
