[TriLUG] running X at the server console

You make a good point about internal vs. external servers.  I probably
should have originally specified that this server is behind a firewall and
is available only on a private network.  So security is a concern, but not
as high a priority as if this box were outside the firewall.

I'm guessing the crashes had to be related to X11 / KDE in some form.  The
system crashed three times in a row when booted into runlevel 5 and has been
fine since booted into runlevel 3.

Thanks to everyone for your advice.  This discussion has been very
informative.
