[Solved] Mouse speed with evdev

Question

The old mouse driver in xorg had an option
Option "Sensitivity" "float"
that can be used to slow down high sensitivity mouse. Is it possible to do the same with the new evdev driver (having found nothing in the Wiki). For now I have
Option "AutoAddDevices" "off"
in the ServerFlags section and I continue to use the old mouse driver (as xorg < 1.4). Can I use the new feature without losing the Sensitivity option?
Edited: The evdev driver support 'Option "ConstantDeceleration" <Float>'  that do the trick; it was not so easy to find it.

Answer 1

Have you tried with xorg.conf?
Edit: Ah, I get it, it won't be recognized anyway.
How about that xset? Can it be used to slow down too?
Or maybe xinput:
[karol@black ~]$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ImExPS/2 Generic Explorer Mouse id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Power Button id=7 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=8 [slave keyboard (3)]
[karol@black ~]$ xinput --list-props 9
