LXDE shutdown menu needs to check CanSuspend/CanHibernate

Hibernation by typing "sudo pm-hibernate" in the console works perfectly.

Yes, we disable hibernation by default in policykit-desktop-privileges. LXDE's session menu needs to check whether suspend or hibernation is possible (CanSuspend/CanHibernate) before offering it, similar to GNOME and Unity's session-indicator. These might not be available due to polkit disabling it, no swap being available, not having enough swap, the machine not supporting suspend, etc.

Is there any guide, hint or workaround available how I can enable hibernation in Lubuntu until the bug ix fixed? As I mentioned above, hibernation works on my PC, but I like to have it by button instead of a console command and password input.

Status changed to 'Confirmed' because the bug affects multiple users.

Please, tell us how to enable this. I have the same problem, hibernation was working out of the box in 12.04.
None of the tricks for other distributions worked so far.
Thanks.

I have the same problem with Ubuntu Server 14.04 with an LXDE-installation from the repository. I cannot even shutdown/ restart the system that way. I get the same error message.

I found that you can at least active the menu by doing the following:

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

The file must have the following content:

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

This will only help, if you can at least hibernate by using the command sudo pm-hibernate as described above.

In may case, as stated here: https://help.ubuntu.com/12.04/ubuntu-help/power-hibernate.html

I had to create the file:
/etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
with the content:
[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

note upower instead of login1, as suggested by hkoch

I make hibernate work by creating the file as described. And I can activate hibernate through the energy settings.

But I cannot activate hibernate through the shutdown menu. This leads to the described error message.

I have the same result:

Problem still here.

sorry guys - I was wrong.
Original file content variant works great:

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

I can hibernate from shutdown menu now.

to comment 2 :

"Yes, we disable hibernation by default in policykit-desktop-privileges. LXDE's session menu needs to check whether suspend or hibernation is possible (CanSuspend/CanHibernate) before offering it, similar to GNOME and Unity's session-indicator."

Exactly my opinion! DO NOT DISPLAY "Hibernate" if CanHibernate is set to false! Just omit it. When there is no permission, it must not show up and then output this ugly error to the user (which normally will only be useful to power users anyhow).

1. paste both entries found here:
https://help.ubuntu.com/14.04/ubuntu-help/power-hibernate.html

2. restart your computer
3. enjoy hibernate in lubuntu! (even though restart is faster on my old laptop lol)

"Yes, we disable hibernation by default in policykit-desktop-privileges" - why it was done?

It should be fixed by adding upstream patch http://git.lxde.org/gitweb/?p=lxde/lxsession.git;a=commit;h=750f98debabed1143561e050f542636a23346438

Ubunu 14.04 and none of mentioned solutions work.
