too sensitive, shaky mouse

[thufir]

I have a "new" used mouse which seems way too sensitive.  I turned the 
sensitivity down to the minimum in Unity (12.04 LTS), but it's no better. 
I ran xinput and checked that mouse moved -- seemed normal, but then I 
don't know how I would distinguish bad behaviour.

Any other settings I can make or test?  It's an HP mouse, and it just kind 
of shaky.



thanks,
