That explians the failure. Choosing a different monitor type in XF86Setup
seems to have fixed the problem ... sort of. (I get a smaller image area
than the full screen and vidtune doesn't help much in resizing it.)

There _was_ a clocks line. The server comlained about it, saying something
about it not making sense for this server. Commenting out the clocks line
only changed the values that the server declared for clocks and still
didn't resolve the problem the way choosing another monitor type did.

I guess I'm still a bit confused about how the config file controles this

Anyway, now I can bring up the server and get a screen. Boy is this
machine dog slow! Enlightenment segfaulted on the first attempt, but then
came up OK. This is a really good torture test machine if you can stay
awake long enought to see the next move ;-)

I really appreciate your sharing what you know. This is one of the major
benefits to Libre Software. Mind share is at least as important as code
share. That is what made Debian so attractive to me in the first place,
aside from the fact that it produces a killer distro.

Thanks again,
