[orca-list] Do I always need a graphical server/interface?

[Rusty Perez <rustys lists gmail com>]

Hi folks,
One of my primary reasons for trying linux was to set up an audio
recording system.
I have achieved this using Nama, jack audio, ETC. but, I'm finding
that I am having trouble with xruns. My system has plenty of power to
do the audio work, but it was suggested to me that maybe the graphical
server is requiring resources which is causing my audio trouble. I do
not need the gnome desktop or a graphical server to do my audio work.

I am a new linux user, so my questions may seem, and may be, dumb, but ...
My questions are as follows:

Does Orca require that the gnome desktop or any graphical desktop?
Does firefox or nautilus--the only graphical programs I'm using
now--require the desktop or a graphical server? Can I just run and use
them from the command line without having gnome running?

Finally, if the graphical server or the desktop are necessary for
these programs to run, can you suggest a less resource intensive way?

Thanks, and sorry if these questions seem silly. I just don't know the
answers! :-)
