Comment 10 for bug 951790

Sorry to be disturbing an ants nest here, but I am one of those annoying people who would like my laptop not to suspend when an external monitor is connected. I have no problems with installing gnome-tweak-tool and changing a setting there to get that behaviour, but the tool claims it is already enabled. Does anyone know whether this is an Ubuntu issue, or a GNOME one, and where I should be looking? Thanks.
