The problem lie in my /etc/X11/xorg.conf file.

Initially it contained the following to use the proprietary nvidia driver.

# RPM Fusion - nvidia-xorg.conf
#
Section "Device"
         Identifier  "Videocard0"
         Driver      "nvidia"
EndSection

Adding   Option     "DPI" "96 x 96"  fixed my font problem.   All is 
well again.
