Mapping mouse buttons: Lingering changes to xinput / libinput.

inkbug

Hello all.
I have two trackballs I've been using instead of computer mice:
A Logitech Trackman Marble, and an Elecom M-DT2 Deft.
The former has no scroll wheel, and the latter's wheel doesn't work, but the rest of the machine is fine.

When I boot into Windows, I use a program called 'X-Mouse Button Control' to cause the trackball's ball to function as a scroll wheel when a button is pressed (both trackballs have at least two extra buttons).

Here on Solus, I found two terminal commands that allow me to achieve the same ends with regard to the Logitech:
xinput --set-button-map "Logitech USB Trackball" 1 2 3 4 5 6 7 8 2
and
xinput set-prop "Logitech USB Trackball" 337 0, 0, 1

However, both commands only last until the next reboot / login, so my question is:

How can I make those two commands stick?

I've never written a startup script, so if that is what's needed, I'd appreciate a nod in the direction of an article on how to do this in Solus.

Any help, or referral to help, will be greatly appreciated.

in Budgie Desktop Settings, under the Autostart section, you can add either programs or commands - maybe adding these commands here would work? (I haven't personally tried this sort of thing yet)

(edit: sorry, I'm assuming you're using Budgie...)

Thanks synth-ruiner , it worked!
I forgot about the Autostart section - I've only used it to autostart applications so far.
It also worked in Plasma, but was a bit more complicated.
