Public bug reported: My Ubuntu screensaver does not blank the screen, ie, it does not turn off the backlights on my monitor.
I dual boot, and my Win10 install does it with no problems, so it's not a hardware thing. What happens is after a period of inactivity, Ubuntu will put up the lock screen, then the backlights will go off for a few seconds and then come back on. I get a perpetual lock-screen that way. I can log back in with no problems. I fact, the rest of the install seems to be just fine.
