Shutdown, reboot, hibernate or suspend your computer later!

GTK GUI which lets the user choose between shutdown, reboot, hibernate or suspend
after a specified amount of time.
Runs on UPower-DBus calls, which surpasses the need for root access.
Working on Ubuntu 10.04, ArchLinux 2009.08 (Maybe other GTK, DBus, DeviceKit systems too).

Version 1.1 released:
- gnome-desktop 2.30 fixes (Ubuntu 10.04 compatible).
(more…)

Gnome 2.30 (Ubuntu 10.04) renamed the DeviceKit.Power to UPower:

$ echo 'dbus-send --system --print-reply --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Hibernate' | at now + 30 minutes

There’s also suspend.
Shutdown (Stop) and Reboot (Restart) works over the system call: org.freedesktop.ConsoleKit

Pre Gnome 2.30

As of Ubuntu 9.10, the gnome-power-cmd doesn’t exist anymore..but…
D-Bus to the rescue!!

Hibernate after 30 Minutes:

$ echo 'dbus-send --system --print-reply --dest=org.freedesktop.DeviceKit.Power /org/freedesktop/DeviceKit/Power org.freedesktop.DeviceKit.Power.Hibernate' | at now + 30 minutes

There’s also suspend.
Shutdown, reboot and logout works over the session call: org.gnome.SessionManager

Hibernate after 30 Minutes:

$ echo 'gnome-power-cmd hibernate' | at now + 30 minutes

The gnome-power-cmd also accepts shutdown and reboot.
