scroll acceleration libinput SynPS/2 touchpad

Hi,

I can't find a way to set a sort of scoll acceleration with synaptics touchpad. I'm running a ThinkPad T460s and using libinput as driver. Here's my current configuration:

tom@thinkarch ~ % xinput list-props 11
Device 'SynPS/2 Synaptics TouchPad':
	Device Enabled (138):	1
	Coordinate Transformation Matrix (140):	1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
	libinput Tapping Enabled (274):	1
	libinput Tapping Enabled Default (275):	0
	libinput Tapping Drag Enabled (276):	1
	libinput Tapping Drag Enabled Default (277):	1
	libinput Tapping Drag Lock Enabled (278):	0
	libinput Tapping Drag Lock Enabled Default (279):	0
	libinput Tapping Button Mapping Enabled (280):	1, 0
	libinput Tapping Button Mapping Default (281):	1, 0
	libinput Accel Speed (282):	0.000000
	libinput Accel Speed Default (283):	0.000000
	libinput Natural Scrolling Enabled (284):	0
	libinput Natural Scrolling Enabled Default (285):	0
	libinput Send Events Modes Available (258):	1, 1
	libinput Send Events Mode Enabled (259):	0, 0
	libinput Send Events Mode Enabled Default (260):	0, 0
	libinput Left Handed Enabled (286):	0
	libinput Left Handed Enabled Default (287):	0
	libinput Scroll Methods Available (288):	1, 1, 0
	libinput Scroll Method Enabled (289):	1, 0, 0
	libinput Scroll Method Enabled Default (290):	1, 0, 0
	libinput Click Methods Available (291):	1, 1
	libinput Click Method Enabled (292):	1, 0
	libinput Click Method Enabled Default (293):	1, 0
	libinput Middle Emulation Enabled (294):	0
	libinput Middle Emulation Enabled Default (295):	0
	libinput Disable While Typing Enabled (296):	1
	libinput Disable While Typing Enabled Default (297):	1

Currently whatever the speed at which I'm scrolling I scroll the same number of lines. Is there a way to reproduce the acceleration speed, only for the scroll?

Thank you
