I have found a solution to this matter. By installing Mouse Setting of Mate, the slider setting makes affect to mouse speed. Launch Software Center and search with keyword "Mouse", then find the icon of Mouse which belong to Mate DE (read description). After install it, you can launch it right from the Software Center as you won't find it through DASH. Once it launched, lock it to the Panel as the setting of mouse speed is reseted every rebooting. I'm sorry if my English is not good enough.
