We are using a Debian 7 machine with the default GNOME 3 installation to display content on an information display. This display needs to remain on until the connected computer is switched off. However, GNOME 3 switches the display off after a few minutes.I can't seem to find a way to control this behaviour in either the system settings tools nor using dconf-editor. There is a prominent Google hit suggesting to change the org.gnome.settings-daemon.plugins.power sleep-display-acorg.gnome.settings-daemon.plugins.power sleep-display-batteryorg.gnome.desktop.session idle-delaykeys, but this did not change anything.So, how does one control and disable screen blanking in GNOME 3?
