I don't use any display manager. How I do the automatic starts at power on:
in /etc/ttys (note the "off" in ttyv8):

ttyv0   "/usr/libexec/getty toorPc"             cons25r on  secure
# Virtual terminals
ttyv1   "/usr/libexec/getty lenaPc"             cons25r on  secure
ttyv2   "/usr/libexec/getty lenaPc"             cons25r on  secure
ttyv3   "/usr/libexec/getty lenaPc"             cons25r on  secure
ttyv4   "/usr/libexec/getty lenaPc"             cons25r on  secure
ttyv5   "/usr/libexec/getty lenaPc"             cons25r on  secure
ttyv6   "/usr/libexec/getty lenaPc"             cons25r on  secure
ttyv7   "/usr/libexec/getty lenaPc"             cons25r on  secure
ttyv8   "/usr/X11R6/bin/xdm -nodaemon"          xterm   off secure
ttyv9   "/usr/libexec/getty lenaPc"             cons25r on  secure
ttyva   "/usr/libexec/getty lenaPc"             cons25r on  secure

In /etc/gettytab :

lenaPc:\
        :al=lena:tc=Pc:
toorPc:\
        :al=toor:tc=Pc:

In /home/lena/.profile (note the startx):

set -- `who am I`
if [ .$2 = .ttyv1 ]; then
  mutt -e 'exec fetch-mail'
elif [ .$2 = .ttyv2 ]; then
  mutt -f ~/Mail/sent
elif [ .$2 = .ttyv6 ]; then
  $EDITOR kalendar
elif [ .$2 = .ttyv7 ]; then
  $EDITOR dossier
elif [ .$2 = .ttyv9 ]; then
  rm .serverauth.*
  startx &
  sleep 7
  centerim -S o -p icq
  centerim -S o -p jab
  sleep 7
  centerim -S o -p icq
elif [ .$2 = .ttyva ]; then
  stty discard undef
  centerim -o
fi
