Bug Description
This system normally has two displays connected which are always on. This problem arose when a TV was connected as a third display. It was preferred to have the TV left "disabled" by unchecking "Use this display" when it was not needed, but leaving its cable connected. However at each startup a GUI will be presented asking for display configuration because the option in Display settings for "Configure new displays when connected" is checked.
If the option for "Connfigure new displays when connected" is then unchecked and the system is hibernated, then on resume X will not start. The only thing that can be done is to start a new terminal session and then startx will bring up a desktop. However the applications that were restored in the resume aren't accessible from this desktop session that has been manually started.
The following were tried until the system was found to be resuming:
1. Disconnected the third display
2. Checked the option for "Configure new displays when connected"
Not until both options had been tried would the system resume after hibernation and start X.
