Screensaver no longer working

After a power-glitch in my home, my Screensaver is no longer working.
The power-glitch was very slight-- it didnt turn off my desktop.

System  > Preferences > Screensaver

slider for "Regard the computer as idle after:"
variously set, from 1min to 17 min, nothing works.

both of following checked
  Activate screensaver when computer is idle
  lock screen when screensaver is active


I also run dpms, from xset -q:
DPMS (Energy Star):
  Standby: 1200    Suspend: 1800    Off: 2400
  DPMS is Enabled
  Monitor is On

I have tried setting dpms to 0 0 0, no help  on Screensaver.

Previously both the screensaver and dpms were working, now only dpms.

Any ideas?
Any CLI instead of the gui?
