** Description changed: The desktop environments would help saving energy, if their shutdown dialogs could by default provide the option (button/checkbox) to schedule a restart. Linux provides a simple way to schedule a restart event that is particularly usefull in conjuction with initiating or scheduling a shutdown or suspend. - rtcwake -m on -s <seconds-util-start-event> + rtcwake -m no -s <seconds-util-start-event> Howerever, just as the shutdown command it requires root privileges. Thus the need for a similar consolekit support. The particular command given in the example above avoids that rtcwake does any switching into another power state (mode -m stays on). This allows that all power state switching is still contolled by whatever power management (userspace) tools are installed, which may often be more stable than the pure kernel/rtcwake method, especially on resume. To test it, just schedule a wake event like above as root, then do a regular shutdown/suspend. Wait, and watch how the real time clock triggers the scheduled power up event and the machine comes back up.
