[Bug 33820] Re: Pressing power button displays dialog, it does not switch off computer

[José M. López-Cepero]

Please note that there is a more deep reasoning in this. If the power button action will be _exactly the same_ as clicking System>Log Out or using the Log Out applet, and will _require_ the user to reach the keyboard/mouse to confirm (that's the key point), there is _no point_ in giving the power button an action, because _there is no gain in using the power button as compared to just using the mouse from the beginning_. You might as well have the button do nothing by default. 

I vote for giving the gconf key moreati has pointed out a simple interface in the gnome-power-preferences dialog. Something like "Power button action": shutdown immediately, shutdown with countdown (like the LogOut applet), ask (bring out the Log Out dialog), do nothing. This would be more consistent and make us all happy. (And then we could argue endlessly about what the default behavior should be :)).
