xdm, icewm....X config indeed

["Valter G. Nogueira Jr." <valter@intersic.com.br>]

Currently I am using woody.

I installed icewm using the following

apt-get install x-window-system
apt-get install icewm

and everything is ok but I was wondering:

What is the xdm startup sequence?
Where is defined icewm as my window manager?

My system doesn't have .xinitrc, .xsession or whaterver!

Thanks
