Title:
  Updating from 11.10 to 12.04, video no longer works

Status in “update-manager” package in Ubuntu:
  Invalid

Bug description:
  I upgraded to 12.04 on one of my machines, and when it starts the
  video blanks, and the monitor reports it is no longer connected. I
  cannot even start in failsafe X mode (Segmentation fault in X).

  Ubuntu is running, because I can ssh to it.

  The last line of dmesg is

  [   35.669872] init: failsafe-x main process (1344) terminated with
  status 1

  
  lshw gives this for the display:
