What's to stop them from shutdown via the physical power button? I know |
| 42 |
that's almost always how I shut down a computer, and I tend not to even |
| 43 |
think of using the menu. |

|

As for how to inhibit, you'll probably need to combine something that reads |
| 46 |
the currently active user sessions, with a patch to the XFCE menu to use |
| 47 |
that information. |
