Comment 1 for bug 162378

If I run displayconfig from the terminal with
  sudo displayconfig
I get the following output when I press the "Second Screen" checkbox:

Traceback (most recent call last):
  File "/usr/bin/displayconfig", line 1474, in slotSecondMonitorToggled
    self.xsetup.setLayout(self.secondary_options[pressed_id])

    gfxcard.setLayout(XSetup.LAYOUT_SINGLE_XINERAMA)

Error in sys.excepthook:

Original exception was:
