Adjust the speed of the mouse and touchpad
如果您在使用鼠标或触摸板时,指针移动太快或太慢,您可以为这些设备调整移动速度。
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.
