How to slow down the mouse in KDE 4

Click on 'Computer' and then 'System Settings', or use the arrow keys to select these and then press Enter, to open the 'System Settings' window shown in Fig 2.

(Some setups may vary. In this example, 'System Settings' is also available from the 'Favourites' tab, as shown in Fig 1.)

Step 2: Adjust the mouse pointer speed

Click on the up and down arrow buttons next to the box beside 'Pointer acceleration' to change the speed of the mouse pointer. The standard value is 2.0. Alternatively, press Tab to highlight the 'Pointer acceleration' box, then use the down and up arrow keys to reduce or increase the speed of the mouse.

In the same manner, you can reduce the sensitivity of the mouse by increasing the value in the 'Pointer threshold' box.

Click on the 'Apply' button or press Alt + A to save your changes.

Click on the 'Overview' button or press Esc to return to the 'System Settings' window. Click the 'Close' cross or press Alt + F4 to return to the KDE desktop.
