xdm at startup?

[Matt Garman <garman@crh3019.urh.uiuc.edu>]

I installed xdm on my system.  Everything is fine, but at install-time
I chose to *NOT* have it start at boot-time.  Now I wish to have it
invoked automatically at startup.  What do I need to do?

Also, is there a way to change the default xdm background (i.e. the
login screen)?  The greyish default is kinda nasty.

Thanks!
Matt
