Beginner Questions

[Mayo, Richard A RDECOM CERDEC STCD SRI]

I'm setting up a FreeBSD box for the first time, so naturally I have a bunch of questions.  I'm sure these are addressed on the web somewhere, but I'm not having any luck finding anything so here goes:

What file controls the way Xwindows sets up after I log on?  I got the graphical login screen, but now I want to start Xwindows with kde rather than twm.



Thanks,
