Adjust the speed of the mouse and touchpad
If your pointer moves too fast or slow when you move your mouse or use your touchpad, you can adjust the pointer speed for these devices.
Go to the desktop and start typing Mouse & Touchpad.
Click on Mouse & Touchpad to open the panel.
Adjust the Mouse Speed or Touchpad Speed slider until the pointer motion is comfortable for you. Sometimes the most comfortable settings for one type of device are not the best for the other.
The Touchpad section only appears if your system has a touchpad, while the Mouse section is only visible when a mouse is connected.
