User permission for poweroff, reboot, depends - LXDE

[volkswagner]

What is required for user to get available Logout Menu options for poweroff, restart, sleep, etc.?

I have a fresh install of 11.04 >minimal which I added LXDE using:

aptitude install --without-recommends xserver-xorg-video-geode xinit xauth x11-utils xfonts-base x11-xserver-utils

aptitude install --without-recommends lxde

Selected yes at the following output:

Do you want to continue? [Y/n/?]

What stood out for me was... policykit-1-gnome. I installed it and
now root user gets the added options for shutdown and restart.

So how do I get regular user (with sudo priv. via admin group option) options for shutdown in LXDE?

Do any of the recommended packages look necessary for this?

I'm not sure yet how I will accomplish, since there still is no powerdev or any group created by adding
policykit.

I also added consolekit, but I'm not sure if that was necessary.

consolekit added messagebus group and policykit added no groups to /etc/group.

I have had this working with Debian without a login manager. Is a login manager now required?

So so sad. How can Ubuntu or any Linux distro become mainstream if internal workings are a mystery?

It seems from my limited knowledge that LXDM package is now required to get shutdown options. I tried XDM and LightDM both of which did not grant user shutdown options in logout menu.

I don't see any package included in LXDM that allows this.

webdt@natty:~$ sudo aptitude install -s lxdm -R

Why can't anyone on #ubunutu, #lxde, and UbuntuForums offer any incite?

If LXDM is required for shutdown shouldn't the dependency move from recommended to required?

Shall I file a bug report on this?
