Further to all that, I found a work-around.  I can start a second X
server, which seems to be OK.

Looking at the output of ps -AH, I have the following relevant
processes.  For the first display:

3128      xinit
3130 tty7   Xorg
3169        failsafeXinit
3194          zenity

and for the second (the one I actually use):

3207      gdm
3297        gdm
3301 tty9     Xorg
3337          x-session-manag
etc. etc.

How do I get stop this first display from starting, and in any case, why
does it give the error messages I listed when the second display doesn't
seem to find any problems?

And is it normal to have gdm apparently starting a second gdm?  On my
desktop computer the equivalent lines show 'gdm-binary' and
'gdm-simple-slav' respectively.
