Re: Inability to shutdown or reboot from gnome



I did some more experiments last night and found that if you boot with the
Grub parameter 'selinux=0' and then login as a user and then go to Gnome by
typing 'startx', you are then able to shutdown the system from the Gnome
buttons - even though you are only a user.

Keep in mind that under these conditions, you don't get any of the
advantages of selinux.

This is probably not what you want to happen in the long run.
