I didn't create this file, as it already was installed as part of the 
dconf-0.16.0-6.el7.x86_64 package, and contained the following:

user-db:user
system-db:local
system-db:site
system-db:distro

The extra system-db records shouldn't be a problem, since they don't 
override the settings we're interested in.

Also existed already, as part of the same dconf package.

I did this, but using a different (larger) timeout value.  I've since 
played around with the timeout value, and found that it worked for very 
small values (e.g. 300).  My current hunch (which I'm still testing) is 
that it works as long as the screensaver and/or screen lock hasn't 
kicked in yet.  (I'm trying to find out which of the two might be the 
issue.)

I had initially skipped the step of creating the lock file, since I 
didn't think it would affect the testing.  When things didn't work 
initially, I created the file (exactly as above), and redid these last 2 
steps, but it made no difference.

I'll report back after I've found more about what timeout values work 
and which don't, and how that compares to my screensaver/screen-lock 
settings.
