Hiding Shutdown/reboot in logout dialog and possible security issue

[Anders Bruun Olsen]

Hi Israel,

I have no idea how you got that from what I have written. My question has
nothing to do with starting X. That is not a problem at all. The problem is
that the logout menu shows the shutdown/reboot buttons, which I do not want
unprivileged users to see. The logout menu is a part of LXDE, not the login
manager (lightdm or slim). In particular the buttons are a part of the
lxsession-logout package.

Having researched LXDE a bit more, it does not seem possible, and it seems
that Lubuntu is not really an option for running a terminal server, without
modifying code, which I do not want to do. I'm gonna go with XFCE instead.
There I can set a policy with polkit, which will at least grey out the
shutdown/reboot buttons (rendering them unclickable). Thanks for your
replies and suggestions :)
