I use Ubuntu 12.04 in my laptop. I'm trying to configure to hibernate when lid is closed. However, not is working.
I did the following steps to solve the problem:

I enable in /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

System Settings - Power

I used the dconf Editor.

When I lid closed instead hibernate is suspend. I try run sudo pm-hibernate and works fine.

Any suggestion ?

Note: try pm-hibernate in a shell before trying this. If it works, go ahead.

I fixed it by...

Using cinnamon-settings / Power to set the event to Hibernate. This sets the dconf values /org/gnome/settings-daemon/plugins/power/lid-close-ac-action and /org/gnome/settings-daemon/plugins/power/lid-close-battery-action to what you want

Editing /etc/acpi/events/lm_lid (gksudo gedit /etc/acpi/events/lm_lid) and filling it with

event=button/lid.*

action=/etc/acpi/lid.sh

Editing /etc/acpi/lid.sh (gksudo gedit /etc/acpi/lid.sh). If it's empty, fill it with

grep -q closed /proc/acpi/button/lid/*/state

if [ $? = 0 ]

then

    su - gabriel -c 'gsettings get org.cinnamon.settings-daemon.plugins.power lid-close-ac-action' | grep hibernate

    if [ $? = 0 ]

    then

        pm-hibernate

    fi

fi

Otherwise, look for the right place to put the code above

Replace gabriel by your username. You have to do the su thing before calling gsettings get because this script is ran as root, and running gsettings get as root would return the preferences for root instead of your user.

You could just call pm-hibernate but then changing options in cinnamon-settings would not work anymore. I did not care to check whether my notebook is on AC or battery, because it's irrelevant: I want the same behaviour always anyway. Maybe someone wants to add an if there?
