Try "sleep 1; xset dpms force off" - I find that just typing
'xset dpms force off', even on single screen systems often
doesn't work because when the command is processed when you
press the Return key down, and most computers these days are
fast enough to have finished before you've let go of the return
key and have processed the KeyRelease event, so the KeyRelease
triggers as a new input event to wake up the screens again.
