Gutsy/Kubuntu: Display Settings > Apply button disabled

[tmp]

Just upgraded my Kubuntu from Feisty to Gutsy.

When entering Administrator Mode in K-Menu > System Settings > Monitor & Display the Apply button is constantly disabled. It is therefore not possible to save/apply my adjusted display settings.

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

Original exception was:

Thank you for reporting this bug and for your efforts to make
Ubuntu better. As Xorg has improved this past year, an unfortunate side
effect of these improvements is that it has rendered several design
assumptions in displayconfig-gtk obsolete. So, starting with Hardy we
are no longer putting displayconfig-gtk forth as a primary configuration
tool, and are putting our development focus into the Screen Resolution
applet. As a result, we do not plan to fix this bug and thus are closing
it.

For more background on this change, please see this page:

Intrepid BETA has been released. Could you please test if this problem still occurs there?

Thanks

Kubuntu no longer uses the display parts of Guidance in Intrepid.
