fedora: where are the client's logs kept?

How can I find out whats going wrong on the client?  Where are the 
client's logs kept?  Is there a FAQ on debugging the clients?

I'm trying to get some x86_64 clients working.

I've installed a x86_64 chroot  and I get as far the LTSP login screen.

When I login as a newly created "test1" user, the authentication is 
accepted (according to /var/log/messages on the server)
the screen goes black for a few seconds, then the LTSP login screen 
returns.   There is no ~test1/.xsession-errors or ~test1/.Xauthority.

My similarly configured i386 clients can successfully open a gnome desktop.

I'm stuck.
