Tutorials/Mouse pointer settings for large displays

From KDE UserBase Wiki

Get a larger mouse pointer and better mouse acceleration

For a larger mouse pointer do this

Press Alt + F2 and enter

kate ../.kde/share/config/kcminputrc

Confirm this with the Return or Enter key .


If the above command brings up an empty file, then you might try editing ../.kde4/share/config/kcminputrc instead.

If you don't have Kate installed, you may use any other text editor instead; for example you could try KWrite

In the Mouse section please add the line


and click on Save.

On your next system start your mouse pointer will be larger.

For better mouse acceleration

Go to System Settings -> Input Devices -> Mouse -> Advanced. There you can set a really fast pointer acceleration, for example 20x and a pointer threshold of 2 pixels.

That acceleration should be OK at medium distances but too fast for larger distances. Here is the trick to get better acceleration:

First press Alt + F2, enter


and press Return.

In the console window you have to get the name of your mouse.

You need the command

xinput list

to find it out.

The name of my mouse is Logitech USB-PS/2 Optical Mouse

Go to System Settings -> Startup and Shutdown. Click at Desktop File -> Add Program. There you can paste this line:

xinput --set-prop "Logitech USB-PS/2 Optical Mouse" "Device Accel Constant Deceleration" 1.2

You have to replace "Logitech USB-PS/2 Optical Mouse" with the name of your mouse. Then click on OK and then on OK again. On your next system start your mouse acceleration will be better.
