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. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/194732 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.
