Bug Description

With 12.04 I can not suspend my netbook (EeePC 1001PXD) anymore. The menu entries for suspend and hibernate are deactivated. When starting the xfce4-power-manager with debug output I get the following:

It looks like the dbus command for hibernate is not allowed. Maybe this is the problem

Hibernation is deactived by policykit-desktop-priviledges, you can reenable it by editing /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla I think.

I guess that suspend support has been disabled in the kernel:
$ dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Suspend

Error org.freedesktop.UPower.GeneralError: No kernel support

Sorry, nothing xfce4-power-manager can do unfortunately...

The suspend command works for me as user and as root:

twoflower # dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Suspend
method return sender=:1.46 -> dest=:1.125 reply_serial=2

The machines suspends.

I'm not sure that I understand why both menues entries for suspending to disk and memory are deactivated? Is this really correct?

When I modify the configuration file /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla as you suggested both menu entries are available again.

I think the status invalid is not appropriate as this is not a correct configuration ... whatever software package has the bug ;-)

As the kernel seems to support suspend on my system there seems to be a difference

Linux twoflower 3.2.0-14-generic #23-Ubuntu SMP Fri Feb 3 23:12:54 UTC 2012 i686 i686 i386 GNU/Linux

Should I open a bug for policykit-desktop-privileges?

Haha, you're right, there's a typo:

> if ( power->priv->can_suspend && power->priv->auth_hibernate)
instead of auth_suspend

I'll add a patch and forward it upstream.

Yeah that looks like a typo :-)

That would fix the problem that both buttons are deactivated.

Do you have any idea why hibernate is deactivated via polkit in the first place?

To be honest it is not that important to me as I use suspend to memory ;-)

See Bug #812394 for the rationale deactivation of hibernation (you can override the policy locally, but I don't think we'll change that for Xubuntu)
