Where's xorg.conf?

Dear CRUXers, I've just installed the latest CRUX, with all of the packages available from CD. It's time to launch my wmaker, neverthless I cannot start X server. I cannot find xorg.conf in my system :/ There is no /etc/X11 ... Maybe I should mention that I skipped CRUX 2.1, 2.2 and 2.3 :) So I jumped into 2.4 directly from 2.0, and I could have missed some important changes... Anyone can help me? Take care, Pawel
