I just started seeing a similar problem, but my output of "$ kcmshell
displayconfig" is a bit different:

$ kcmshell displayconfig

The problem is the same whether or not I run as root. The line about
"VidModeExtension" may be important, although my Xorg.0.log file
indicates that the extenstion _was_ loaded. Whetever the cause of the
problem, the actual bug seems to be in DisplayApp(parent, name), which
is probably just returning a null pointer when it's not supposed to..
