Title:
  [Trusty] Need additional udev rule to avoid efi framebuffer to be
  primary

Status in “udev” package in Ubuntu:
  Triaged

Bug description:
  At least with the Trusty 3.13 kernel the driver name seems to have
  changed. So I had to add the following line to

  --- /lib/udev/rules.d/78-graphics-card.rules ---
   DRIVERS=="nouveau", GOTO="graphics_end"
   DRIVERS=="efifb", GOTO="graphics_end"
  +DRIVERS=="efi-framebuffer", GOTO="graphics_end"

   KERNEL=="fb[0-9]*", ENV{PRIMARY_DEVICE_FOR_DISPLAY}="1"
  ---

  Without thiat, a virtual machine (again) gets stuck while ejecting the
  conflicting framebuffer.
