XDM is not a window manager - it is a display manager. In short it 
provides a GUI login and then starts your window manager of choice.

So if you want a GUI login and a GUI DE, you need both a DM and an WM.

I use XDM + Openbox, and it works very well indeed for me. Vastly 
preferable to some heavyweight like GDM, IMHO.

The handbook provides excellent guidance on installing and configuring
