Select the time in the bottom right corner to open the System menu.
In the System menu, select the Settings button .
In the Settings window, select Device from the left-hand menu.
In the Device section, select Touchpad.
On the Touchpad screen, adjust the slider for Touchpad speed.
Above the Touchpad speed slider is an option called Enable touchpad acceleration.When this option is enabled the distance your pointer moves across the screen will depend on how quickly you move your finger across the touchpad. Try enabling and disabling this option to see what you find more comfortable.
Note: If this does not work it could be because someone else manages your computer settings (an IT department or administrator). If this is the case, you will need to contact them to access these settings or for further help.
