Automatic shutdown / hibernation after x minutes in suspend?

  • 772

I have an embedded battery powered device running Ubuntu and want to reduce power consumption. The idea is that if a user does not use a device for ca. 30 min. then the device will automatically shutdown or hibernate.

Is it possible to automatically shut down or hibernate Ubuntu after spending x minutes in suspend?

shutdown

  1. Suspend is an hardware managed state, such function if available would need to be implemented at the BIOS level, or at least would require BIOS support.

    Unless your BIOS provides such programmable function, no, it is not possible.

  2. You can try gshutdown from the Software Center.

    If the default options are not working, try changing from Edit>Preferences>Actions the "autodetect" option to "custom command", press "Turn off the computer" and fill it with the shutdown -h now command.

  3. The installation here : http://gshutdown.tuxfamily.org/en/download.php works well (gshutdown_0.2-1_i386.deb)
