Ubuntu – How to modify the options for the power button

power-management

When I press the power button a dialog opens, but I want to shutdown the system without receiving "Do you really really want to shutdown?". How can I choose a direct shutdown action on a pressed power button?

I had the same problem with the 11.04 version, but I don't remember the solution and yesterday I upgraded to Ubuntu 11.10.

Lid Close Action

To set up the Laptop Lid Close Action you have to install Advanced Setting (or the Gnome Tweak Tool). It is in the USC (Ubuntu Software Center) under either tweak or Advanced Settings. If installed press the super button and type in tweak or advanced and choose the Advanced Settings. When it opens choose the shell tab;

Advanced Settings Before

Press the arrows and choose you desired on both on AC and on battery;

Advanced Setting After

Default buttons behavior

Install dconf-tools:

sudo apt-get install dconf-tools

Press alt+f2 and open dconf-editor (or in a terminal type dconf-editor)

Navigate to org.gnome.settings-daemon.plugins.power and set your default button-power action there:

On some systems you will also need to mark the item suppress-logout-restart-shutdown.

replace the 'hibernate' with the action you want.

The number of processes should not be different. You have to remember when counting the pids to include the script itself and the subprocess created.

I created the following that should work for your requirements. You should alter the timeout depending on how quickly you want the multiple button presses.

#!/bin/sh
# /etc/acpi/powerbtn.sh
# Initiates a shutdown when the power putton has been
# pressed.

timeout=0.8
pid_count=$(pidof -x powerbtn.sh | wc -w)

( if [ $pid_count -eq 4 ]; then
        sleep $timeout
        /etc/acpi/sleep.sh
    else
        sleep $timeout
        pid_count_now=$(pidof -x powerbtn.sh | wc -w)
        if [ $pid_count_now -eq 2 ] && [ $pid_count -eq 2 ]; then
            poweroff
        fi
        exit
    fi
) &
