Touchpad stop working after KDE start

[d3x73r]

Hi!

I've recently upgraded my KDE Desktop, and since this my touchpad stoped to work after loggin KDE.
It moves on Wellcome screen and when i create a new user. So i think this is a KDE config that I'm missing here.
Does anyone know how to reset the touchpad configs to look like a new user? I don't wanna just lost all configs of kde, creating a new user, because this problem!

Thanks!
