Hiding Shutdown/reboot in logout dialog and possible security issue

[Anders Bruun Olsen]

Hi Israel,

Yeah, I can see that I might have focused a bit too much on what I
perceived as a security problem in lightdm.

I will try gnome-session-manager and see if that is better for my usage
than lxsession-logout. Thanks for your replies :)
