With the "success_boot" I booted with the external monitor turned off and then when desktop showed on to internal monitor I switched the external monitor on. (The result was a desktop on the external monitor as expected.)
With the "filed_boot" I booted with the external monitor turned on and after waiting till activity seized I Ctrl-Alt-F1 to command line mode and made the dumps.
