Some time ago I'd discovered new UBS mouses are moving the mouse pointer much too quick on the screen - even if just a very short move was done by the mouse.
Using PupX will NOT give options/parameters to slow down the mouse pointer.
So, long ago, I'd edited the file /root/.xset.sh script to fit to my personal needs.
This is the content of my /root/.xset.sh script (the mean parameters is marked in bold):
