I posted a question and noticed people weren't distinguishing correctly between many of these things: Windows Managers vs Login Managers Vs Display Managers Vs Desktop Environment. Can someone please clear this up, i.e. tell us the difference between them and how they are related perhaps?
What category does Xorg fall under? What about Gdm/Kdm/Xdm? People also talk about X. What is X?

From the bottom up:
In theory (and mostly so in practice) any of those components are interchangeable. You can run kmail using GNOME with WindowMaker on Xorg.
