Unable to disable mouse acceleration completely

Support KDE Plasma
1

I’m unable to completely disable mouse acceleration on the latest version of kde bundled with manjaro. I have tried the following remedies Mouse acceleration - ArchWiki and double checked that it’s using libinput, however despite using the flat profile i still appear to have some acceleration, how do i verify if that’s really the case and if so, how do i disable it for good? Thanks.

I had a similar problem where on every reboot mouse acceleration came back. If I opened the mouse settings and moved the acceleration one tick, applied it and put back to the default middle position, it was gone again. So in the end I had to use an autostart script like suggested in the wiki.

You could post the output of your xinput properties.

With mouse acceleration enabled the only difference for me was:

libinput Accel Profile Enabled (431): 1, 0
