Thanks, Brendan.  To the extent that I dug a little further among the 
screen savers/lockers that lxlock supports (xscreensaver, 
gnome-screensaver, slock, xlock, i3lock and xdg-screensaver), I found 
that slock is too simple and a tad alarming (just a black screen with no 
indication about what is going on, and if you type anything the screen 
turns blue -- again with no explanation).  Xlock is no longer in the 
repos (considered insecure).  And I'm */imagining/* that xscreensaver, 
gnome-screensaver and xdg-screensaver bring a lot of dependency baggage 
and perhaps some unwanted effects.  (With xscreensaver, for instance, we 
used to have to log in at 2 screens after a resume.)

So I stopped at i3lock as a decent compromise.  It's a very light 
package, and I can create a static screen explaining that the screen is 
locked and the user should enter the password.

I would prefer an actual login screen such as we get with light-locker, 
but I didn't take the time to see if xscreensaver, gnome-screensaver or 
xdg-screensaver could be installed without big dependencies and 
configured to provide just a clean screen-lock function.
