[SOLVED] prevent lock screen when hibernating

[dresnu]

Hello, I'm using uswsusp to hibernate my laptop running Kubuntu, but when it resumes the session is locked.

Is there a way to resume directly to the desktop instead of having to input my password everytime?

Thank you

You need to open up the screensaver settings and unselect (uncheck) the lock desktop option.
In KDE I think you'll find the screensaver settings in control center.

Unfortunately it's not that. Screensaver is disabled already and all options are unchecked.
The problem lies somewhere in KDE guidance and the HAL scripts it invokes during hibernation.

If I hibernate from a terminal with the s2disk command I can resume regularly on my desktop. On the other hand if I hibernate through the Log out options in Kmenu I get a locked screen when resuming.

I'm not sure how to do it within KDE but, one thing you could try would be to edit /etc/default/acpi-support. Look for LOCK_SCREEN and change the value to false. I'm not sure if that will work in Hardy anymore though.

I'm still on Gutsy but what you suggested didn't work anyway. Indeed LOCK_SCREEN was true in acpi configuration but switching it didn't make any change.

From what I found out when I press the button to hibernate what gets called is this script /usr/lib/hal/scripts/hal-system-power-hibernate:
#!/bin/sh

PRIVILEGE=hal-power-hibernate
if [ "$HAVE_POLKIT" = "1" ] ; then
if [ "$HAL_METHOD_INVOKED_BY_UID" != "0" ] ; then
RESULT=$(polkit-is-privileged --privilege $PRIVILEGE \
--user $HAL_METHOD_INVOKED_BY_UID \
--system-bus-unique-name $HAL_METHOD_INVOKED_BY_SYSTEMBUS_CONNECTION_NAME 2>&1)
IS_PRIVILEGED=$?
if [ "$IS_PRIVILEGED" != "0" ] ; then
echo org.freedesktop.Hal.Device.PermissionDeniedByPolic y >&2
echo $PRIVILEGE refused uid $HAL_METHOD_INVOKED_BY_UID >&2
exit 1
fi
fi
fi

if [ -n "$HALD_UNAME_S" -a -x ./$HALD_UNAME_S/hal-system-power-hibernate-$HALD_UNAME_S ]; then
exec ./$HALD_UNAME_S/hal-system-power-hibernate-$HALD_UNAME_S $@
else
echo "org.freedesktop.Hal.Device.UnknownError" >&2
echo "No back-end for your operating system" >&2
exit 1
fi


that then calls this one /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux:
#!/bin/sh

POWERSAVED_SUSPEND2DISK="dbus-send --system --dest=com.novell.powersave \
--print-reply /com/novell/powersave \
com.novell.powersave.action.SuspendToDisk"

unsupported() {
echo org.freedesktop.Hal.Device.SystemPowerManagement.N otSupported >&2
echo No hibernate script found >&2
exit 1
}

But in this code there doesn't seem to be any reference to screen/session locking.

Ok, solved it.
I found there is an option in Power Manager that says "Lock screen on resume". Disabling it did the trick... easier than I thought.

Thanks for the replies
