I have a similar problem as this post: How do I turn off the screen saver using the command line?
However, these new commands (and likewise if I set the options from the GUI) only seem to work if I am actually normally logged in to X.
I am using an XBMC-only desktop session, and when I type this command:
gsettings get org.gnome.desktop.screensaver idle-activation-enabled
I get "true" (which explains why it keeps going blank after 10 mins), but when I type this command:
gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
I get the following:
** (process:4909): WARNING **: Command line 'dbus-launch --autolaunch=b3ac84dfb4159464a026d84900000006 --binary-syntax --close-stderr' exited with non-zero exit status 1: Autolaunch error: X11 initialization failed.\n
Is there any way of altering this setting system wide?
