Title:
  x11 gets blank screen after apt-get

Status in x11-utils package in Ubuntu:
  Confirmed

Bug description:
  do-release-upgrade -d to get to Ubuntu 14.04; loving 14.04 for some
  weeks. Routine 'apt-get update && apt-get -y dist-upgrade && if [ -e
  /var/run/reboot-required ]; then echo "REBOOT required"; else echo
  "Not required to reboot at `date`."; fi' gets x11 blank screen after
  reboot.

  Tried:
    pushd /etc/X11
    cp xorg.conf.failsafe xorg.conf
    reboot
  No help.
