No way to set pointing device speed
Submitted by Yan Pas

Libinput doesn't provide options to set pointer's speed, it obly provides acceleration settings. So every DE doesn't have such setting. Here is workaround: http://askubuntu.com/questions/205676/how-to-change-mouse-speed-sensitivity
Please add function to libinput library to set pointer speed
PS: I'm not sure, whether it is the correct place for opening the bug, maybe problem is somewhere else.
