LinuxQuestions.org - Suspend/Hibernate on a desktop machine

Answering to myself after a significant advance...

I Still don't have my entries in the system menu but... I now have a suspend button in the shutdown widget (that appears when cliking system > shutdown). It looks like gnome-power-manager autostarts with my session now that it is installed.

My first try to hibernate lead to a notication window saying "hibernate problem" and nothing happened. I then ran gnome-power-manager in a console: I killed the currently running one and restarted with

Code:

gnome-power-manager --verbose --no-daemon

I then came accross the following errors/warnings:

The first one was trivial.

Code:

[gpm_screensaver_enable_throttle] gpm-screensaver.c:123 (22:12:39):      setThrottleEnabled : 0

*** WARNING ***

[gpm_screensaver_enable_throttle] gpm-screensaver.c:134 (22:12:39):      The name org.gnome.ScreenSaver was not provided by any .service files

GNOME Power Manager has encountered a non-critical warning.

Consult http://bugzilla.gnome.org/buglist.cgi?product=gnome-power-manager for any known issues or a possible fix.

Please file a bug with this complete message if not present

[gpm_screensaver_enable_throttle] gpm-screensaver.c:137 (22:12:39):      gnome-screensaver service is not running.

[gpm_screensaver_enable_throttle] gpm-screensaver.c:142 (22:12:39):      setThrottleEnabled failed

Althought this didn't look mandatory to succesfully hibernate, I fixed by installing gnome-screensaver.

Code:

yum install gnome-screensaver

This is the important part

Code:

[gpm_hal_handle_error] gpm-hal.c:192 (22:14:14):        Hibernate failed

(No hibernate script found)

I had a look at directory /usr/share/hal/scripts/ and found a file there hal-system-power-hibernate. Examining that file I came accross the following line:

Code:

#RedHat/Fedora only support pm-utils

elif [ -f /etc/redhat-release ] || [ -f /etc/fedora-release ] ; then

        if [ -x /usr/sbin/pm-hibernate ] ; then

                /usr/sbin/pm-hibernate

                RET=$?

        else

                unsupported

        fi

And guess what... no usr/sbin/pm-hibernate on my system. This is how I fixed:

Code:

yum install pm-utils

Now I can Hibernate ! Hurray ! And the password widget on screensaver once screen is locked is a lot more sexy :)

Upon first resume, I noticed I had some problems with my network and had to stop/start my ethernet interface. Diging arround in pm-utils scripts (/etc/pm/hooks) I saw a 10NetworkManager file and stopped on the following piece of code:

Code:

# Tell NetworkManager to shut down networking

    dbus-send --system                        \

        --print-reply                          \

        --reply-timeout=2000                  \

        --dest=org.freedesktop.NetworkManager  \

        /org/freedesktop/NetworkManager        \

        org.freedesktop.NetworkManager.sleep >/dev/null 2>&1 0<&1

    return $?

It came out there is a nice NetworkManager service which I started issuing a:

Code:

/etc/init.d/NetworkManager start

and configured for auto-start with:

Code:

chkconfig --level 5 NetworkManager on

Now I have a very sexy network icon in my notification area and I'm almost sure I will have no more network problems on the next resume. This is what I'm going to try just now.

See you later :)
