Mouse Acceleration Settings in X

Mouse acceleration under X had never really seemed as natural as under Windows, but a little research turned up settings which made X mouse movement just as good.

In the .xinitrc file (or under Redhat 7.3, .Xclients-default), put:

xset m 29/20 0

Then, in the XFree86 configuration file (/etc/X11/XF86Config-4 under Redhat 7.3, /etc/X11/XF86Config under FreeBSD), set Option "resolution" "200" against the mouse device, like so (Linux):

Section "InputDevice"
   Identifier  "Mouse0"
   Driver      "mouse"
   Option      "Device" "/dev/mouse"
   Option      "Protocol" "PS/2"
   Option      "Emulate3Buttons" "off"
   Option      "ZAxisMapping" "5 5"
   Option      "Resolution" "200"
