Default starting from version 4.4 is hal. Using sudo You have to allow the user(s) to execute $installdir/libexec/xfsm-shutdown-helper with sudo. Install sudo and run visudo (root) and add the following line (replace prefix with the correct path): %users ALL = NOPASSWD:prefix/libexec/xfsm-shutdown-helper Add the user to the users group (root): gpasswd -a username users When you logout and login again, the shutdown and restart buttons should be sensitive. For more information you can referrer to the xfce4-session and sudo documentation. Using hal and dbus Make sure that the hal and dbus daemons are started on boot, and that you are running a recent version of dbus (at least 1.1). Refer to your distribution for exact steps. In the steps below the groupname “power” is used. This is DEPENDING ON YOUR DISTRIBUTION. Your /etc/dbus-1/system.d/hal.conf should contain a section similar to this: policy group=power allow send_interface=org.freedesktop.Hal.Device.SystemPowerManagement/ ... /policy Add the user to the power group (root): gpasswd -a username power When you logout and login again, the shutdown and restart buttons should be sensitive. /Quote http://wiki.xfce.org/faq As you can see above, the dbus method that you're using also requires a dbus policy + adding yourself to a specific group.

How to hibernate from the command line without typing password
I asked this question on this list a while back and although I did get a helpful response that would have led to a solution, it would not have led to the better solution that I recently discovered so I thought I'd post this in case it might be helpful to anyone else searching the list. I found the solution in this blog post: http://thehacklist.blogspot.com/2009/09/suspendhibernate-from-command-line.html the command in the post itself didn't work for me, but one given in the comments did. This works for me in Debian Lenny running the default Gnome desktop. You can send a signal via dbus asking for the computer to be hibernated with the following command: dbus-send --session --dest=org.freedesktop.PowerManagement --type=method_call /org/freedesktop/PowerManagement org.freedesktop.PowerM anagement.Hibernate In the above blog post's comments you'll find a similar command to suspend the computer. I used this command to add a one-click hibernate button to my Gnome panel (as a custom application launcher). Normally you can't hibernate without multiple clicks in Gnome, and it always asks you whether you want to suspend, hibernate, restart or shutdown, of which shutdown seems to always be the default. I just kept choosing shutdown and then cursing because what I always want is to hibernate. If hibernate works for you, why would you ever want to shutdown? Hibernate seems to me to be what computers should always do, as they start up much faster and all your context is preserved. I also saved the command as an executable script called 'hibernate' so that I can hibernate from the command line by just typing hibernate.
