X font puzzles

[steve%prd.co.uk@localhost (Steve Blinkhorn)]

For over 10 years I have run our office network with a clutch of
'nettop'-style machines with specific roles but overlapping
capabilities, so that any one machine can die without affecting
overall functionality.  One of these, running NetBSD 7.0, repeatedly
fails to boot multi-user: it's main role was to run Xvnc to provide
access to the network of NetBSD machines to PC workstations.  This
arrangement has worked very well, so well I had not looked at how it
was set up for years.

So I switched the service over to an identical machine whose
principal role was to provide outward-facing services: mail, named
etc.  It appeared at first to be a seamless transition, until I saw
that characters typed into an xterm were echoed horizontally offset to
the right, so were largely unreadable.  Characters programatically
output to the screen are rendered correctly.  I use lucidatypewriter
as my STD_FONT, 18 point in deference to my presbyopia.  A fix for
this would be really helpful.

So I turned to a NetBSD 9.2 box, and here I hit a different problem.
Using Xvnc as started by the same vncserver script as before, I get
the right screen dimensions (1920x1080) but not the font I want or the
size I want.  It looks like there was a major reorganisation of fonts
some time between 7.0 and 9.2, with more layers of configuration.  How
do I specify th lucidatypewriter font I want (it's there, I can see it
through xlsfontas, but I don't get told where it is in the
filesystem).

Finally, with native X on 9.2, despite specifying a geometry of
1920x1080 in my startx script, I get a 1024x768 display.  Why?

I'm about to replace all my old machines but need to feel properly in
controld when I do.

BTW, all machines amd64.
