  last -a -n 1 $USER | awk '{print $10}'

seems to work OK. But it's a bit flawed this way of doing things IMHO, as
at least on my RH5.2 machine, you get an incorrect $DISPLAY setting when
you start a local rxvt.

What I usually do is write the current display into ~/.display from the
.xsession or .xinitrc script, then source that from the ~/.bashrc file --
that way everywhere gets the right value, as long as ~ is shared via NFS.

like so (in the .xsession):

  $HOME/bin/fulldisplay > $HOME/.display &

where ~/bin/fulldisplay is a script like this:

  #!/bin/sh
  [ "${DISPLAY:-unset}" = unset ] && exit 1
  case "$DISPLAY" in
	  :0* ) echo `uname -n`:0 ;;
	  * ) echo $DISPLAY ;;
  esac
  exit 0

BTW regarding sweetr's mail -- I can see your point. Personally I didn't
respond because I know FA about configuring gnome or E ;).  As to the lack
of replies: I think a common reason for this would be because a reply
message saying "can't help here, I don't have a clue" would be widely
construed as just a waste of bandwidth.
