In case anyone is suffering the same problem.   I fixed the display
scaling issue.  

The ATI Catalyst control center in KDE allows you to change the scaling
options.  My display was set to about 7% underscaling in the display
manager DTV1 menu, on the adjustments tab.  All I needed to do was move
the scaling slider all the way to the right, and the display scaled
perfectly.

Now, if only I could get compositing working :-/
