Speedup Mouse-Pointer

[rethus]

Is there a way to speedup the mouse pointer more than it’s possible via the UI?

I have the M570 Trackball from logitech and want to speed up the mouse pointer a bit more.
Is there any way to increase it (e.g. via some x11 files)?

Have a look at the xset command. It can be used to adjust mouse acceleration (amongst other things).
Work out the parameters which suit your needs, then stick the command in your ~/.bashrc / ~/.zshrc / etc. so it’s automatically applied.

Ok, got it.

Do it like this:

Edit: sudo nano /etc/X11/xorg.conf.d/10-evdev.conf

Section "InputClass"
    Identifier      "Logitech M570"
    MatchProduct    "Logitech M570"
    Driver          "evdev"
    Option "AccelerationProfile" "2"  # 1=Standard, 2=Konstante Beschl., 3=Adaptive Beschl. 4 = Keine Beschl.
    Option "AccelerationNumerator" "3" # Erhöhen für schnelle, verringern für langsamer. Default bei 2 
    Option "AccelerationDenominator" "1"  
    Option "ConstantDeceleration" "2" 
    Option "EmulateWheel" "true"
    Option "EmulateWheelButton" "9" # Forward-Btn & Trackball = Scrolling
EndSection

Those three Acceleration-Options do the magic.

I’ve also added the Super-Cow-Black-Ninja-Ultra-Pro scrolling… means if I hold the forward button on the mouse, I can scroll with my Trackball.
That are the last two Emulate-options you see in there.

Some additional settings you can make
