long story short, im "trying" to switch from w10 to linux, currently using arch linux or antergos and kde. now.

i want to change my mouse sensitivity. in the mouse settings all i get is mouse accelleration etc. but there is NO option for sensitivity. help?

Maybe this helps: How can I set mouse sensitivity, not just mouse acceleration? - http://unix.stackexchange.com/questions ... celeration

Should Rog131's answer not be sufficient could you please try to explain further what you are trying to achieve?

If you want to change the mouse sensitivity, this still works in KDE neon 5.9. You don't need to use the libinput instruction the author added for Fedora users.
