Is there anyway to reduce the mouse sensitivity in Ubuntu 12.04?

I've used the slider on the systems settings to set it to the lowest point but it's still too fast.

You should be able to change Option "Sensitivity" for your pointing device in xorg.conf or a configuration file in /usr/share/X11/xorg.conf.d (or create one). See this forum topic and this Xorg.conf documentation. It should be possible for someone to put together the information in this comment, to produce an actual answer to this question (but I feel this is not by itself good enough to be an answer). –  Eliah Kagan May 10 '12 at 18:59
    
@EliahKagan For me, fiddling with this forced me into console on reboot. The answer below worked fine though. –  Sparhawk Apr 24 '13 at 23:34

  1. looking for mouse device id or name
  2. $ xinput --list
    ⎡ Virtual core pointer                      id=2    [master pointer  (3)]
    ⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
    ⎜   ↳ A4Tech USB Full Speed                     id=10   [slave  pointer  (2)]
    ⎜   ↳ A4Tech USB Full Speed                     id=11   [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)]
        ↳ CHESEN USB Keyboard                       id=8    [slave  keyboard (3)]
        ↳ CHESEN USB Keyboard                       id=9    [slave  keyboard (3)]
    
  3. setting mouse sensivity
  4. $ xinput --set-prop 10 "Device Accel Constant Deceleration" 4
    don't know why there are two same names so have choosen id by random. and it worked out.
  5. telling system to do this after logging in
  6. create script:
    #!/bin/bash
    xinput --set-prop 10 "Device Accel Constant Deceleration" 4
    then run command:
    $ gnome-session-properties
    and add the script to the list.
    don't forget about chmod +x.

information was found here and here.

in terminal type

vi mouse.sh

then paste your config in

xinput --set-prop 12 "Device Accel Constant Deceleration" 5

quit and save

then do

sudo chmod +x mouse.sh 

then in gnome-session-properties put the mouse.sh file in.

then you're done
