I've been trying out a trackball mouse and I find that it is entirely too sensitive, so I tune it down by setting its Device Accel Constant Deceleration
to 1.5, I feel like this dials in the X axis fine, but my Y axis motions are underwhelming.
Simply put, is it possibly to configure X and Y sensitivities separately?
My environment is fairly stock Linux Mint 17.1, so Ubuntu-trusty–like, Debian, Gnome 3, and the rest of the stack that I am less familiar with.
