Re: zenmap as root error

You can just check if the DISPLAY environment variable is set. Like this:

----------------------------------------8<----------------------------------------
import os
import sys

if 'DISPLAY' not in os.environ.keys():

    print "Unable to start graphical application. Please, set DISPLAY \
environment variable."
    sys.exit(0)

import gtk
----------------------------------------8<----------------------------------------

Put this before "import gtk" in zenmap main file to avoid some warnings too.
