What if you call the corresponding lightdm_get_can_ function once
the user has clicked on the menu item?

If the answer is yes, then do the requested action. Otherwise there
are 2 possibilities:

1. Display a dialog box saying that the action is not possible.

2. Display a dialog box saying that the action may fail, and do the
   requested action.

If the lightdm_get_can_* functions can be trusted at this time, then
(1) is the best solution. Otherwise (i.e. lightdm_get_can_* don't say
"yes" though the actions can really be carried out), choose (2).

There you have feedback.
