attempting use of KVM switch a disaster

[George E Noon]

So, Dan (or somone)
    Please clue me in; i have attempted about four times now to edit 
that xorg.conf-file
-- I seem to be doing OK, and seem to have everything right, but when I 
attempt to save the
file (& the changes I've made), I am rather bluntly informed I do not 
have the right to
do so. I am fairly certain that what i am missing i have likely read 
before but don't recall, or
it should be obvious but isn't.......
    Thank you.
