There are no debug messages even with --debug. "off" works just fine.
"standby" and "suspend" make the screen go blank, which is what I
suppose they should do.

I've noticed something else: contrary to what I wrote in my original
report, the screen is actually turned off by g-p-m, but there is a delay
of a few minutes where the screen is blanked but on. This confused me. I
still think it's kind of weird, but it's not a problem to me since it
eventually turns off anyway.
