  Bob,

  A slight increase in verbosity might help here :-)

  If you get a message along the lines of "cannot open display ...
  connection to ... refused: client is not authorized ..." then your
  system is of the opinion that user "root" is not allowed to open
  windows on a desktop that belongs to user "bob"; if you're not on a
  network, try entering "xhost +" while you're still bob, i.e. just
  before you su. Don't do that on a network since it enables others to
  sniff out what you're doing.

  Bye
  Frederik
