I then tried starting the frontend on RPi, and same result::  Goes to DB config screen, and on finish it turns off the monitor.  When I turn it back on, it shows the desktop and turns off the monitor again (a detail not in my earlier posts).  Turn it back on again and I have the desktop.  Strange, no?

There is not much in config.xml, but the IP address for the backend and the password are correct, and I can successfully ping the backend from the RPi:

<Configuration>
  <LocalHostName>my-unique-identifier-goes-here</LocalHostName>
  <Database>
    <PingHost>1</PingHost>
    <Host>192.168.1.200</Host>
    <UserName>mythtv</UserName>
    <Password>********</Password>
    <DatabaseName>mythconverg</DatabaseName>
    <Port>3306</Port>
  </Database>
  <WakeOnLAN>
    <Enabled>0</Enabled>
    <SQLReconnectWaitTime>0</SQLReconnectWaitTime>
    <SQLConnectRetry>5</SQLConnectRetry>
    <Command>echo 'WOLsqlServerCommand not set'</Command>
  </WakeOnLAN>
</Configuration>


Per Bill's suggestion I tried starting from the command line with LIBCEC disabled.  That did not seem to work, but it did make me realize that I could get the log from the frontend that way.  Here is the first part of it.  Indicates a connection is being refused, but not on the port for mythconverg:
