I double-checked, but there wasn't.  I created the file
/usr/local/etc/X11/xorg.conf.d/driver-intel.conf
as per the handbook, but without success.

One other thing I tried (I don't know why this didn't occur to me
before) was to disconnect the external monitor I usually use.  But
again, I just got a black screen, this time on the built-in display.

I had already added that, but is there any way of verifying it has
taken effect?  The line "Using syscons driver with X support (version
2.0)" looks suspicious to me.

There is no .xsession and the .xinitrc I've been using is pretty
straight-forward:

=================================
if [ -f $HOME/.Xmodmap ]
then
   xmodmap $HOME/.Xmodmap
fi

if [ -f $HOME/.Xresources ]
then
   xrdb -merge $HOME/.Xresources
fi

if [ -f $HOME/.xbindkeysrc ]
then
   xbindkeys
fi

exec wmaker
=================================

I tried temporarily renaming it, but no change to symptoms.

I do that anyway.
