Xubuntu 14.04: how to enable hibernate?

Question

I'm using Xubuntu 14.04 64 bit. I know that question been asked a billion times, but all of them consist of editing following file:

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

That file does not exist on my system. I tried com.xubuntu.enable-hibernate.pkla but doesn't exist either, locate command doesn't find it.

Solution

Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

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

Look for

[Disable hibernate by default in upower]
[Disable hibernate by default in logind]

Change the value of "ResultActive=no" to "ResultActive=yes" in both, press ctrl+x to exit the file. It will ask to save the change or not. Press Y to save the change, if you're on Ubuntu restart your system.

Edit

Just tried this on Xubuntu 16.04, and Ubuntu 16.04. and it also works.

For Ubuntu 16.04 I had to reboot for it to work.

two questions why locate com.ubuntu.desktop.pkla does not find it? and why is hibernate disabled by default?

[Mitch]

As far as the first one, use sudo locate com.ubuntu.desktop.pkla, and it will find it. As for the second one I really don't know for sure, but it might be a bug.

[Lynob]

why using sudo? I used to search for files in /etc and var without using sudo

[Mitch]

If you look at the folder the file is in, its owned by root. I tried it, and it works with sudo.

[Lynob]

yes I just tried it too and it works too but all I'm saying that I can search for files, say php.ini which is located in /etc/php5/apache2/php.ini and it works without sudo and as far as I know, etc is also owned by root.

[Mitch]

If you look at the polkit-1 folder, you will see an X on the folder, which means that you are neither the owner nor in the group that has permissions to read/write/execute to that particular folder/file. Where as /etc does not.

Without using sudo the file doesn't exist for me, but shows up once i add sudo to the command

finally. best answer ever. other solutions does not work for me. many thanks.

Edits of a package owned file in /var, as in this solution, will be wiped out next time the package is updated. Better to create a file in /etc as showed in the official documentation.

@Lynob, for why they are disabled by default, see here (sites.google.com/site/easylinuxtipsproject/bugs) under the section titled, "Hibernate and suspend don't always work well: they make some computers malfunction or even enter a coma".

This also works for Kubuntu 16.04

I double-checked the polkit-1 entries - hibernation is/was not disabled in that file, but it's been missing from my power manager for as long as I can remember. Are there any other culprits? In general I feel like this is a very silly configuration, especially as a default - I can't imagine why a guest/unauth would have more privileges than a user, nor any scenario where authorized users would be prevented from logging out and granting themselves whatever privileges follow this pattern. I see this is supposed to protect the session, but from the owner?

[John P]

From this page it appears the label "disable by default" does not imply that "yes" corresponds to disabling hibernation. Serves me right for assuming...

I just want to confirm that this solution works also on Xubuntu 20.04. Thanks for it!
