Hibernate missing in login screen

Solution 1:

Here is a solution. Hibernate option in desktop session and login screen as below:

Desktop Session :

Login Screen :

First open your terminal and add the following :

sudo gedit /var/lib/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

A txt file now is opened add the following lines :

[Re-enable hibernate by default in upower]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

[Re-enable hibernate by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate
ResultActive=yes

Save and reboot your system after that hibernate should appear and function well.

Solution 2:

The configuration for hibernation already sits in file

/var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

Just open this file and enable hibernation: ResultActive=yes The resulting code looks like this:

[Disable hibernate by default in upower]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

and

[Disable hibernate by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate
ResultActive=yes

That's all. Now you will see hibernate option in power dialog and login

Solution 3:

The address of the policy kit file changed in Ubuntu 14.04.

Follow the same steps as before, except replacing the file:

/var/lib/polkit-1/localauthority/10-local.d/hibernate.pkla

with this one:

/var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla

Try this one

sudo gedit /var/lib/polkit-1/localauthority/10-local.d/hibernate.pkla

Finally, 'restart' nautilus by executing nautilus -q and the indicator option should spring up.

Solution 4:

That's a bug, which will hopefully be solved in Ubuntu 14.04. It is impossible to enable hibernation in login screen.
