Johnny, this afternoon I got around to putting the old cable back in, only to 
find that I can't get X correctly configured again.  I have no X.  I managed 
to get to a text screen and vi xorg.conf, putting in exactly what you 
recommended above (maybe that was for digital, not analogue?).  I still can't 
startx.  I see

(==) Using config file: "/etc/X11/xorg.conf"
(EE) NV(0): No valid initial configuration found
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found
XIO: fatal IO error 104 (Connection reset by peer) on X server ":0.0"
     after 0 requests (0 known processed) with 0 events remaining.

Can you recommend a really basic xorg.conf to get me started?  Thanks

Anne
