How do I turn off the screen saver using the command line?
these settings will help
gsettings set org.gnome.desktop.screensaver lock-delay 3600
gsettings set org.gnome.desktop.screensaver lock-enabled false
gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
recheck with dconf-editor
when using the gui, these properties will also change in dconf-editor.
killall gnome-screensaver ; xset dpms force on
