Subject: Re: Finding one certain line in a file is easy but how to look for headlines and something just under this certain headline?

thx for your help, I solved it now this way (I know pretty messy) but it works fine:

 system('cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak')
  xorgbak = File.open('/etc/X11/xorg.conf.bak')
  xorg = File.open('/etc/X11/xorg.conf','w')
  drifound = false
  compofound=false
  while line = xorgbak.gets
     driverflag = true if /Section "Device"/.match(line)
     driverflag = false if driverflag && line.gsub!(/(Driver\s+)"(.*)"/, '\1"fglrx"')
     (driflag = true & drifound = true) if /Section "DRI"/.match(line)
     driflag = false if driflag && line.gsub!(/(Mode\s+).*/, '\10666')  
     (compoflag = true & compofound = true) if /Section "Extensions"/.match(line)
     compoflag = false if compoflag && line.gsub!(/(Option\s+)"(.*)"/, '\1"Composite" "Disable"')
     xorg.puts line
  end
  xorgbak.close
  xorg.close
  xorg = File.open('/etc/X11/xorg.conf',"a")
  if not drifound
      xorg.puts''
      xorg.puts'Section "DRI"'
      xorg.puts'        Mode    0666'
      xorg.puts'EndSection'
  end
  if not compofound
     xorg.puts''
     xorg.puts'Section "Extensions"'
     xorg.puts'        Option "Composite" "Disable"'
     xorg.puts'EndSection'
  end
  xorg.close
