[Bug 987664] Re: allow to set restart/resume time

[hakaishi]

OKAY! Now I know a way to make qshutdown execute multiple commands
(using &&). In the coming new version this will be possible. Then you
can just put sudo or gksudo or what ever before the command and that's
it. If you want that there is no prompt for a password, just add the
command to the sudoers disabling the Password. ;)

  allow to set restart/resume time

Bug description:
  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>

  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.
