Here's how I solved this The Right Way (tm), in case anyone else searches for this and finds this thread. On recent Fedoras (F14, F13, not sure about others) this is done by hacking PolicyKit. Shutdown and Restart are configured by editing /usr/share/polkit-1/actions/org.freedesktop.consolekit.policy and changing <allow_active>yes</allow_active> to <allow_active>auth_admin_keep</allow_active> for both "Stop the system" and for "Restart the system". There are two other actions in there (stop/restart when others are logged in), which already have the more restrictive "auth_admin_keep" authorization setting. Suspend and Hibernate are done in the same fashion, but the file to edit is /usr/share/polkit-1/actions/org.freedesktop.upower.policy At this point, one no longer has to worry about hiding or removing the gnome "power" button from either the gdm greeter or a user's panel. When the button is clicked and any of shutdown/restart/suspend/hibernate is selected, the system will ask for the root password before proceeding, which is exactly what I was looking for. Thanks to all who offered suggestions and ideas that eventually helped me pick the right keywords to google for :) --Gabriel > On Fri, 14 Jan 2011 17:59:31 -0500 Gabriel L.
