I tried to navigate here: /usr/share/X11/xorg.conf.d/90-mouse.conf/

But in this directory is no 90-mouse.conf

How do I disable mouse acceleration?

1 Answer 1

  • create a new empty file

    sudo nano /usr/share/X11/xorg.conf.d/50-mouse-acceleration.conf

  • paste the following lines into the file

Section "InputClass"
    Identifier "my_mouse"
    MatchIsPointer "yes"
    Option "AccelerationProfile" "-1"
    Option "AccelerationScheme" "none"
    Option "AccelSpeed" "-1"

  • logout and login (to restart the session)

more examples can be found here: Setting mouse acceleration (but note that the path to .conf file in your Linux distribution is different)
