The slider on the mouse preferences for 'sensitivity' does nothing. my usb mouse and trackpad are a bit slow. ..acceleration works good. I have mint 10 installed on my hp laptop.
lowered sensitivity for my ArcTouch mouse with these mouse settings: system tools>system settings>mouse and touchpad "acceleration" slider: set "slow" (slowest) "sensitivity" slider: set "fast" (fastest...that's right, fastest!) this is worse than counterintuitive, it must be a programming error
