Public bug reported:
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.
