IIUC, you have set your desktop background to black, and you think that 
you have set the KDM background to black.

It isn't that simple: sorry about that. :-)

There is an X command option which I think is "-br" which substitutes a 
startup black root window background for the standard 1 pixel pitch gray 
checkerboard.  With KDM, this is set in: $KDEDIR/share/config/kdm/kdmrc:


Then there is the background color for KDM which is set in the Control 

	System Administration -> Login Manager :: Background

Then the: "$KDEDIR/bin/startkde" script might be setting the background:

	xsetroot -solid <color>

and you probably want to simply remove that, but don't remove:

	xsetroot -cursor_name left_ptr

And then finally there is the Desktop background in the Control Center:

	Appearance & Themes -> Background

And then there are utilities such as xloadimage that can also set the 
root background color.
