i would like all mice that i plug into my pc to have no mouse accel by default and for there to be no mouse accel in the login screen.

I have not tested this, but you might be able to set the default pointer acceleration in KDE/plasma to none by putting the following line in the [Mouse] section of $HOME/.config/kcminputrc

PointerAccelerationProfile=1

This won’t affect the login screen though.

The way I understand the situation is:

  • pointer acceleration is handled by libinput.
  • libinput does not have configuration files, but is intstead only configured by the running compositor (kwin in case of plasma - based on user preferences).
  • Login managers have do their own compositing & don’t load user prefs.

That means: unless the login manager offers you a way to set libinput options, there might be no way to do that.
