fyi...i had this exact same problem running ubuntu 14.04.

the monitor powersave function would work fine when sitting at the
machine and interacting directly with it.  when i'd step away, the
monitor would power-off as expected.

but when i would interact remotely via VNC (desktop sharing) and stop
using the machine, the workstation's monitor would stay on indefinitely
regardless of the powersave settings.

this undesired behaviour was consistent whether i was using xfce-power-
manager or light-locker to manage the monitor powersave settings.

but when i tried xscreensaver instead (after removing both xfce-power-
manager and light-locker), it worked fine -- the monitor powersave would
activate whether i was working directly with the machine or accessing
remotely via VNC.

Title:
  Screen power saving mode will not resume after using VNC prorgram

Status in gnome-power-manager package in Ubuntu:
  Invalid

Bug description:
  After using the remote desktop program & the VNC viewer programs that
  are included with the Gutsy version of Ubuntu, the screen
  blanking/power saving mode function will not resume on the computer
  that was BEING controlled remotely after the VNC session has been
  ended by the computer that was DOING the controlling.

  I have the screen power saving mode set to go blank after 3 minutes of
  inactivity on the computer.

  Once the VNC session is ended the controlled computer will NOT go
  into/resume the screen blanking function unless the mouse/cursor is
  moved or a key is pressed (Of course, if I am at a remote location,
  say at work and the computer being controlled is at my home, then It
  is sort of hard for me to either move the mouse or press at key, if I
  am not there in person).

  After the mouse/cursor is moved (when I get home) the screen blanking
  function WILL resume as normal.  However, it would seem to me that
  once the VNC session is ended that this screen blanking/power saving
  function should resume without any user intervention.  It is as if
  somehow that computer thinks that there is still activity (i.e. either
  mouse movement of keyboard activity is taking place) even though there
  is not.

  If you need anymore information, please let me know.

  Thanks.
