I’m on fresh install of Nixos with KDE plasma and mouse acceleration seems to be broken. In KDE settings there is a checkbox that seems to have no impact on whether it’s on or off.
I’ve also tried adding services.libinput.mouse.accelProfile = “flat” to my configuration.nix and after nixos-rebuild switch it did nothing. Adding 50-mouse-acceleration.conf to /etc/X11/xorg.conf.d/ from Mouse acceleration - ArchWiki did’nt help either.
Strangely enough, xinput shows that enabled accel profile is 0, 1, 0 which should be flat

Before that I’ve tried mininal nixos installation, and with no desktop environment(I’ve installed dwm) I experienced the same issue.
I’m pretty new to nixos and it’s really confusing. I prefer hidpi mouse settings and with acceleration it’s unusable. Also wayland is not an option for me, because I want to use my pc for gaming.
