Thanks everybody who respond to my request.

James, that was my first attempt, and couldn't get autologin to work in the
first place. From what I have read in many other posts I'm not alone there.
Everybody points to ldm as the source of the problem, and I even tried a ldm
replacement (don't remember where I got it, had read so many docs before
asking for help here) but couldn't get it to work either. Any help here?

Just to make things easier for me (I'm trying to educate myself about ltsp)
I installed a fresh copy of ubuntu-7.10-server for the sake of having no
gnome nor wm to worry about, then installed ltsp5. Then created a .xsession
file with a call to xcalc as a test and, after logging in the client
complied about not having desktop manager/window manager. Then installed
blackbox wm and the test succeeded, but now even if .xsession file does not
exist because somehow blackbox is automatically launched. For now, its ok to
have a wm, what bothers me is not knowing why things happens. I'm not
worried at this time about performance/refinements just want the whole thing
to work.

Please be patient with me, I'm working hard trying to acquire all the
required knowledge while doing this project and of course having fun!.
