I'm using Arch Linux with i3 window manager. I have tap-to-click and also tap-to-drag enabled in xinput, so currently if tap twice with one finger, it successfully drags. Additionally, tapping once with two fingers works like clicking the right mouse button.
However, tapping twice with two fingers, doesn't drag with the right mouse button. (I know it doesn't work because if it did, I would be able to resize windows with it). I suspect because two finger movement on touchpad is reserved for scrolling.
How can I enable two finger double tap to drag?
I'm currently using Arch linux with kernel 5.2.0 and xinput version 1.6.2, and here's the output for
bash $ xinput list-props 'SynPS/2 Synaptics TouchPad'
