I know, It's being fixed. Please create a bugzilla and we can discuss
the details there:
http://www.gnome.org/projects/gnome-power-manager/bugs.html

Who ever is logged in at the moment. You can change this
in /etc/dbus-1/system.d/hal.conf, and if no-one is logged in, then the
policy of root.

Anyone who can use org.freedesktop.Hal.Device.SystemPowerManagement can
issue methods to HAL, and anyone can try to store policy.

Nope, been down this route, please see the archives:

Please see the g-p-m archives, this has been extensively discussed.

I don't think we need any more init states.

Ohh I hope so too! Again, create a bugzilla for the (what component
would be the logout window?), tell me the bugzilla number, and I can
offer some sample code to integrate it with Hibernate and Suspend
methods in HAL. We already know if the computer is able to suspend or
hibernate (well, if support is compiled into the kernel, and that's no
guarantee it's going to work...) and can trivially call a
suspend_to_disk or suspend_to_ram with one dbus call.

No, g-p-m can work with lots of other stuff talking to hal at the same
time.

Thanks!

I'm sure the KDE guys can easily use the information and methods in HAL
to improve the existing KDE pm-framework. I'm more than keen on this to
happen. GNOME Applets do not do what I need at the moment, (see
http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=174160 ) so until
then we should use a notification icon.
