I want to use the Option "Disable touchpad while typing" in the touchpad configuration(Settings->Mouse and Touchpad->Devices). It is working while using a value > 1sec. For my usage it seems way to long. When I try to use a value like 0.9 it doesn't work at all. Anyone knows a fix for this. I want to get like 0.5 or something similar.
Working with: Xubuntu 16.04
