I’ve spend quite some time reading about xf86-input-synaptics, libinput, etc etc…
I still just cannot find out how to do this…
I’ve been on Linux Mint for 10 years, and have had this in my
xinput set-button-map 'SynPS/2 Synaptics TouchPad' 1 1 3 4 5 6 7
…which will turn the “middle button” on the touchpad to behave like the “left button”
How do I persist this on Arch/EndeavourOS?
