I set the pointer speed in System Setting as low as possible and it is still way too fast. It is a logitech M185 and I am running Ubuntu 12.04. I have the same mouse with my Mac Mini and it isn't crazy fast like the one on my Ubuntu computer.

I just found the solution in this external page.

It seems that you have to modify the Device Accel Constant Deceleration. The original value is 1, I tried a few settings and it seems that it works perfectly with 2.8 for me.

I used the following command, where 10 is the device id, so you should change the 10 value with the corresponding for you:

xinput --set-prop 10 "Device Accel Constant Deceleration" 2.8

How to know your id device? With this command you will see the list of your device and the id:

xinput --list --short

awesome but one issue is when the device reconnects it then resets that setting. – Goddard Jun 27 '13 at 21:25

As unlikely as it sounds, try unplugging the USB dongle and plugging it back end.
Sometimes this happens when it has hibernated then come back.

Try this -

It's a Linux version of Logitech's Setpoint software that can act as a configuration tool with various options, including sensitivity control.
