I am embarrassed to admit that I had forgotten about use of 'fg'.
In my many years of running "emacs filename &",
I have not had to use 'fg'.
What usually happens is that a separate emacs window comes up
and leaves my terminal window (where I entered the emacs command)
still free to be used, while also working in the emacs window.
No need for 'fg' at all.
This normally works the same,
whether running as user byers
or as root(su -)
or as root(su).

My brief attempts at "emacs -nw"
show an emacs window that takes over the terminal,
which is not what I want.

But something else has since changed:
as a result of another thread re "f16....xfce"
with much help from Joe Zeff,
I now have xfce working properly,
and also no longer have to use C^alt-f2, startxfce4,
to get graphical display.
The last thing  fixed required "yum install gdm".

Moreover,
now when running
"emacs filename &" as root (su -)
now works perfectly : a new emacs window,
terminal window stll free. No use of 'fg' required.

Running "emacs filename &" as root (su)
still gives that previously reported error msg,
but again still gives me a separate working emacs window.
 No use of 'fg' required.

Thanks for your response
