# Ubuntu – Wireless mouse sensitivity is too high

logitech-mouseUbuntu

I have a laptop with Ubuntu 12.10 x64 installed. A Logitech M325 wireless mouse is connected to it using Logitech Unifying technology.

The sensitivity settings slider is moved to the lowest setting. The touchpad sensitivity is comfortable, but the mouse's sensitivity is still painfully high.

Is there any way to manually change sensitivity even lower then system settings allows?

• Steps:

1. Execute

xinput list


to find out the mouse's device ID.

The device name should start with Logitech Unifying Device. Wireless PID:, followed by a number. If you have a wireless keyboard as well, there might be several entries. In this case, you'll have to try them one by one.

2. Execute

xinput set-prop ID "Device Accel Constant Deceleration" value


to modify the property Device Accel Constant Deceleration, where ID is the ID from step 1 and value the desired deceleration. The default value is 1. Try 2 first and increase if needed.

3. If you can't find a setting that suits your needs, execute

xinput list-props ID


to enumerate all modifiable values.

4. To make the changes permanent, create/modify ~/.gnomerc with your favorite text editor and add the desired command(s) to it.
