Thank you for the suggestion.  I installed system-config-display, and
after running it, if I use the KDE tool to change the resolution,
it now attempts to do so.  Unfortunately, I get the same results as
I got with xrandr; most of the resolutions just give me a black
screen.  If I use system-config-display to change the resolution,
I also get the same result, with the added problem of having to
boot single-user to delete the xorg.conf file to get the display
back.
