No system-config-display ?

[Bob Goodwin]

    I just installed [yum] system-config-display and get the following
    message when I try to use it:

        [bobg at box9 ~]$ system-config-display

        (xconf.py:4947): Gdk-WARNING **: DESKTOP_STARTUP_ID contains
        invalid UTF-8
        Traceback (most recent call last):
           File "/usr/share/system-config-display/xconf.py", line 376,
        in <module>
             dialog = xConfigDialog.XConfigDialog(hardware_state,
        xconfig, rhpxl.videocard.VideoCardInfo())
           File "/usr/share/system-config-display/xConfigDialog.py",
        line 641, in __init__
             if len(self.xconfig.layout[0].adjacencies) > 1:
        IndexError: index out-of-bounds

    All I want to do is determine what display parameters I am using?

    What's wrong here?
