There are two items in the dialogue - acceleration and sensitivity. The
first controls when the mouse goes into overdrive, the second controls
how fast the mouse cursor moves on screen relative to how fast you move
the actual device over the mousing surface.

It is *exactly* what Dotan is looking for.

KDE has so many bells and whistles, I'd certainly expect it to have this
too. Maybe it's just better hidden.

Dotan - try "man xset", under the "mouse" subcommand. It looks to me as
if it might do what you want with a threshhold of zero, so the
"acceleration" parameter applies to all mouse movement - e.g. "xset
mouse 1/2 0". Haven't tried it though.

Also, you may find xinput helps. Use "xinput --list --short" to find out
what devices you have, then feed that name into "xinput --list-props" to
find out what twiddlable properties it has, them use "xinput --set-prop
<whatever>" to set that property.

I think you'd have to put these things in a script to run at startup.
Nice thing about the xinput solution (if it is a solution) is that it
will apply only to the particular mouse you configure with it - other
mice will be left alone.
