[Bug 35833] Display Module Fails to Load

[TrinitronX]

Public bug reported:
https://launchpad.net/malone/bugs/35833

Affects: kde-systemsettings (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Something got totally messed up in my install of kubuntu-desktop,
specifically under the kde system settings.

On my fresh install, clicking on Display under the system settings gives an error message saying that the module failed to load on some occasions, especially when trying to use 'administrator mode'.
However, on one occasion, after multiple reboots, I was able to get the dialog running.  I used it to change my display options so that I could run 2 displays as an extended desktop configuration.  After applying the changes, I exited the dialog and rebooted.

However, something was totally messed up with the settings, and my
display is now defaulting to a very large one, however it is not
stretching to fit both displays, I believe this is a problem with my
video card (ATI 9800pro) not being configured for Xinerama at the
moment.  However, I only wish to be able to open the display dialog
again to reset the settings back to normal.

After multiple reboots again, I still am unable to get the Display
dialog working, it always gives me this error:

"The module Display could not be loaded
The diagnostics is:
Possible reasons:
*An error occurred during your last KDE upgrade leaving an orphaned control module
*You have old third party modules lying around.
Check these points carefully and try to remove the module mentioned in the error message. If this fails, consider contacting your distributor or packager."

My install of kubuntu-desktop went fine before, and no errors were
reported during it... so I believe the Display module is broken somehow.

I also ran kcontrol from the command line, and tried opening the display
dialog under "Peripherals>Display", and got this debug info from the
command line:

This is all the info I can provide at the moment, hopefully this helps.
