Before the bug: - There are 3 buttons: Logout, Reboot, Shutdown in the Application Dashboard widget. Steps to reproduce the bug: 1. Go to System Settings > Startup and Shutdown > Desktop sessions 2. Uncheck the option "Offer shutdown options" -> Result: the Application Dashboard now has only one button "Logout" 3. Redo step 1+2, but in step 2 check the option "Offer shutdown options" -> Result: the Application Dashboard now still has only one button "Logout" -> bug. (temporary fix: Change Application Dashboard to Application Menu and change it again) Expected behavior: - After the step #3 above, the Application Dashboard has 3 buttons: Logout, Reboot, Shutdown.
Disabling the shutdown options automatically removes them from the favorites as the actions become unavailable. You can re-add them at will by dragging them from the Power / Session category to the system favorites area, or using the context menu.
