fvwm2 and xterm placement

[ktb]

Hi, I'm using fvwm2 for my windows manager under xdm.  I'm trying
to get the initial xterm window to appear in the center of my screen instead
of the upper left hand corner.  I looked at,

/usr/doc/fvwm2/README.sysrc.gz  and it said to:

 init.hook
                Additional commands for the InitFunction, which is
                automatically executed by fvwm upon startup.  This
should
                contain commands to start any programs you want to
always
                start, such as a welcome screen or an xterm.

                The lines in init.hook should be "continuation lines"
                for a function, such as:

                        + "I" Exec xterm

So I created a sub directory, .fvwm2 in my home directory and added the
following file,

~/.fvwm2$ cat init.hook
+ "I" exec xterm -geometry=80x40+154+137 &


I also tried editing, /etc/X11/Xsession  changing the geometry line,

1)
  case $1 in
  failsafe)
    if grep -q ^allow-failsafe /etc/X11/config; then
      exec xterm -geometry 80x40+154+137
    fi
    ;;
  esac
  ;;
esac


I don't know what I'm doing wrong could one of you could help me out?
Thanks,
Kent
