No, they haven't.  They're still in custom.conf, where they've been for 
some time.  The buried settings discussed earlier apply to GDM, which 
has not itself been deprecated.

It sounds like the X server is crashing or locking up.  Try this:  Reset 
the machine running the X server.  Possibly reset the F17 host as well, 
since it's complaining about too many sessions from your X server host. 
  When you run X -query, capture data using strace:

strace -f -s 256 X -query ... > /var/tmp/xtrace.txt 2>&1

After the X server locks, cancel the trace with Ctrl+C.  Don't send the 
file to the list, because it'll be large.  I don't think it has any 
sensitive data in it, so maybe compress it and post it somewhere it can 
be retrieved (http://ge.tt ?) or send it to me.  What we're looking for 
is output from glibc similar to what I included previously.  It'll be on 
lines near the end which indicate calls to writev().
