None of that is any real help with the problem, which is once locked, not 
even John the ripper can find a working password to let you back in.

But I did fix it, with my usual damn the topedo's attitude, I removed the 
exec perms from both of the light-locker utilities, and killed those in 
memory.  Now the blanker kicks in but does not invoke dpms to turn the 
monitor off (I won't say it ever did) , and I can walk back over to it, 
touch the mouse or the spacebar on the keyboard, and I am instantly 
looking at a screen ready to go back to work. Sure beats having to hit 
the reset to reboot it in the middle of a longer job, like building a 
realtime kernel.

dpms, FWIW, doesn't work on a jessie install on a pi-3b either. The 
blanker does blank, but does not power down the monitor.
