core file should be wherever X started up.  Depending on how you start,
this can be in a number of places.  I use startx to launch my X session
(think for a few minutes -- what *really* is the function of an X
display manager other than to provide the overhead of an X session when
you explicitly don't need one).   I'd recommend  you do the same.  You
can shut down your X display manager with:

    # /etc/init.d/<foo>dm stop

...as root.

Usual candidate locations would be /, $HOME, and /root for an
[xgkw]dm-initiated session.

To save your X session output to a file, try:

    $ startx -- 1>.startx.log 2>&1 & 

...to launch X

You may also want to check your "ulimit -a" output to find out if you've
truncated core files.  I've done this as I don't usually care to know
what's in them:

	core file size (blocks)     0				# no cores
	data seg size (kbytes)      unlimited
	file size (blocks)          unlimited
	max locked memory (kbytes)  unlimited
	max memory size (kbytes)    unlimited
	open files                  1024
	pipe size (512 bytes)       8
	stack size (kbytes)         8192
	cpu time (seconds)          unlimited
	max user processes          256
	virtual memory (kbytes)     unlimited

Cheers.
