 Applications can tell the system not to suspend (it's called 'inhibiting
 suspend') but they have to choose to do so. I don't think presentation
 apps or music players do. Totem, for instance, does inhibit suspend
 while it's playing video (not sure about music).


is ti possible to have a list of applications that run by default, and
everything else is considered activity?

 i don't understand how this power saving works. my thinkpad suspended while
 playing music, my desktop suspended while displaying a slideshow. why the
 power management ignored those two activities?
 
 
 
 

Hi,

I think that is supposed to be the way it works, meaning based on input
(keyboard/mouse), not what programs are running.

Mplayer and probably most movie players can suppress the screen saver.
So then the problem simplifies to can GNOME be made smart enough to
leave the system powered up if the screen is on even if no keyboard or
mouse activity is going on.

They can suppress the X screensaver, but the X screensaver and power
management isn't good enough for gnome, they have to have their own
entirely separate system which operates on entirely different
mechanisms.

gnome-mplayer can be configured to use the gnome-session-manager to
inhibit screen saving.
