Comment 13 for bug 859075

I can confirm the same issue applies to Xubuntu. It's not so easy to alter /usr/lib/xfce4/session/xfsm-shutdown-helper to include the settings suggested to KDE.

Also, while the system never seems to power down when choosing the logout button, there is a slight difference when you use the laptop's power button to initiate shutdown. When using that method, the system sometimes powers off and sometimes doesn't, with no obvious difference between success and failure.
