[Bug 39603] Display Module in KDE System Settings "fails to load"

[pat.pannuto]

Public bug reported:

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


Description:
This bug appeared after modifying my xorg.conf to make nvidia twinview
work.  I am currently running a fully-updated versions of Dapper Flight
6.

It is reproducable in either of two ways:

(1)
Open the kMenu and select "System Settings".
Click on "Display"
"The module Display could not be loaded" (screenshot attached)

(2)
Open a konsole and type "kcontrol"
Expand "Peripherals" and click on "Display"
It will pause for a second, and then show the same screen that was there previously.

While using method 2, nothing is fed back to the console until clicking
on display, when the following appears:

pat at ubuntu:~$ kcontrol
