[newbie] root applications in x

[cyberclay]

Hey,
  I'm having trouble running applications that require root privleges
in x.  After su'ing, execution of say..linuxconf..reports:

Gtk-WARNING **: cannot open display:

Also, some GNOME applets (such as cpumemusage_applet) report the same
error.

Regards,
  cyberclay
