I am using Ubuntu 18.04 on a laptop (Lenovo X1 Carbon) and I managed to activate the Xinput Tapping Drag lock as I intended. (
xinput set-prop 11 283 1 where 11 is the device, 283 is the Tapping Drag Lock id, and 1 is to activate it)
The problem is that it comes with a timeout and I would like to know if there is a way to remove the timeout or change it. I did not find any option on Xinput to change it. Does any one knows how to do this?
