I need to set buttons manually with xinput set-button-map id 3 2 1 ... The mouse is Eclipse Touch Mouse. Connection was established using standard Ubuntu bluetooth feature without passcode. The left-handed setting resets after short inactivity time (probably mouse gets into sleep mode or something like this) and mouse gets back to right-hand mode. How can I make the setting for left-hand use permanent, so that I can use my mouse left-handed all the time without the need to set button map manually? I am a total beginner in Ubuntu world. Thank you.
