2.10.3 Session and System Idle Times
gnome-screensaver
is a session daemon that monitors user input (if the mouse
has or has not been moved and if the keyboard has or has not been pressed) then starts
a timeout. When the value of this timeout reaches the value set in Screensaver Prefer-
ences (using the Regard the computer as idle after option), then the login is marked as
“session idle.”
As soon as the session is marked idle, GNOME Power Manager starts it's own system
timer. When the timeout set in GNOME Power Manager Preferences is reached, and
the CPU load is idle, then the idle action is performed (such as turning off the screen,
suspending or hibernating the computer).
To make this clearer, the sliders in GNOME Power Manager Preferences are set to start
at the value of the session-t 1 minute, as GNOME Power Manager Preferences
cannot logically trigger before the session is marked as idle. If you adjust the value of
the session idle timeout in Screensaver Preferences, the start time of the sliders in
GNOME Power Manager Preferences will change accordingly.
