lowering mouse speed (and sensitivity) in ubuntu 10.04

I bought a Evoluent VerticalMouse 3 a while back, and regardless of what settings I used, the mouse’s movement was just too fast on Ubuntu. I set the mouse sensitivity slider in gnome to the least sensitive, but even that wasn’t enough. After a bunch of playing around, I discovered that running this does the trick:

$ xinput --set-prop 'Kingsis Peripherals Evoluent VerticalMouse 3 ' 'Device Accel Constant Deceleration' 6


You can get a list of all properties with
xinput --list-props 'Kingsis Peripherals Evoluent VerticalMouse 3 '

Note that the Vertical Mouse 3 has a space at the end of its device string. This took me about 5 minutes to figure out.
