monitor - Ubuntu 16.04.1 screen not turning off, screensaver not activating - Ask Ubuntu


since installing caffeine screen no longer turning off. installed screen saver, , isn't working either. caffeine wasn't running. unistalled caffeine, still no luck. suggestions how making screen turn off again? it's set @ 3 minutes. disabled lock. thank you!

maybe deleted necessary package:

sudo apt-get install gnome-screensaver

should enable screensaver:

gsettings set org.gnome.desktop.screensaver idle-activation-enabled true

time in second before display darkens. 

gsettings set org.gnome.desktop.session idle-delay "time/s"

maybe dim option disbled:

gsettings set org.gnome.settings-daemon.plugins.power idle-dim true

if not have display power management installed, x-server takes on task.

xset +dpms && xset s on         -> enabel dpms , screensaver xset +dpms dpms 600 1200 1800   -> standby, suspend , off set in seconds
