[Bug 1292041] Re: Lockscreen doesn't turn off the screen


Same issue here. Newly installed, updated and "upgraded" Ubuntu 14.04 LTS.
Monitor ASUS 27" through HDMI.
After the established timeout, screen does blank out, and monitor detects the "poweroff" and starts powering off. But then the lock screen comes up with request to log in password, and monitor comes back up again and stays on infinitely.

I'd say this definitely looks like a bug, because the monitor does
detect the shutdown sequence. It looks like a bug (or missing monitor
shutdown sequence) on the lock/login screen.

Bug description:
  The new Unity lock screen doesn't turn off the monitor screen.

  I can wait as long as 10 minutes after activating the lock screen and
  the monitor still doesn't trun off. Then when I unlock the screen and
  don't use mouse or keyboard monitor will turn off (it's about 5
  seconds after unlocking).
