tl;dr; I want to change coasting of my touchpad, however xfconf-query doesn't do that.

[code] $ xinput list-props "SYNA2393:00 06CB:7A13 Touchpad" | grep Coast Synaptics Coasting Speed (295): 20.000000, 50.000000 $ xfconf-query -c pointers -p /SYNA2393:00_06CB:7A13_Touchpad/Properties/Synaptics_Coasting_Speed -n -t double -t double -s 0.0 -s 0.0 $ xinput list-props "SYNA2393:00 06CB:7A13 Touchpad" | grep Coast Synaptics Coasting Speed (295): 20.000000, 50.000000 $ xfconf-query -c pointers -p "/SYNA2393:00_06CB:7A13_Touchpad/Properties/Synaptics_Coasting_Speed" -n -t double -t double -s 0.0 -s 0.0 $ xinput list-props "SYNA2393:00 06CB:7A13 Touchpad" | grep Coast Synaptics Coasting Speed (295): 20.000000, 50.000000 [/code]

Using 'synclient' works.

[code] $ synclient CoastingSpeed=0 $ synclient CoastingFriction=0 $ xinput list-props "SYNA2393:00 06CB:7A13 Touchpad" | grep Coast Synaptics Coasting Speed (295): 0.000000, 0.000000 [/code]

Version: 4.12.0
