# How to change libinput's mouse acceleration on Fedora 28 KDE?

So I tried setting the properties for acceleration in xinput but I get:

property 'libinput Accel ...' doesn't exist, you need to specify its type and format, only properties that exist are:

    libinput Accel Speed (298):     -0.110000
libinput Accel Speed Default (299):     0.000000
libinput Accel Profiles Available (300):        1, 1
libinput Accel Profile Enabled (301):   1, 0
libinput Accel Profile Enabled Default (302):   1, 0


I manage to do it with set-float-prop but I don't see any change..

I tried using these settings: Arch Wiki But to no avail.

Xset is also not doing anything, as well as xinput set-ptr-feedback on the mouse.

Is there anything special that I need to do, I tried using extreme values so I can see the difference, nothing works?
