[Bug 531573] Re: No console nor monitor detection with efi boot on MacBook 5, 1

[Andrew Cranwell]

I have a MacBook 5,2 and have been booting in EFI mode with rEFIt, a
manually compiled grub.efi and the following grub.cfg:

set debug=video
set timeout=10
insmod efi_gop

menuentry "Linux (no agp, force acpi)" {
  root=(hd0,3)
  fakebios
  linux /vmlinuz root=/dev/sda3 video=efifb agp=off acpi=force
  initrd /initrd.img
}

Have you tried an insmod efi_gop line? See

Title:
  No console nor monitor detection with efi boot on MacBook 5,1

Status in “grub2” package in Ubuntu:
  New

Bug description:
  Binary package hint: grub2

  I am trying to boot my Macbook Pro Unibody (5,1) in EFI mode rather
  than BIOS (with rEFIt).

  I have followed the main guidelines at
  http://grub.enbug.org/TestingOnMacbook, and I can launch grub2 efi
  application within rEFIt menù.

  I started using a simple grub.cfg:
  menuentry "GNU/Linux, Linux 2.6.31-20-generic" {
  	set root=(hd0,4)
  	linux	/boot/vmlinuz-2.6.31-20-generic root=/dev/sda4
  	initrd	/boot/initrd.img-2.6.31-20-generic
  }

  Grub2 will execute kernel and initrd, the system will bootup (I can
  ssh on it), but I cannot see ANYTHING on the console (totally black).

  I tried with optional parameter like video=(efifb|vesafb) and adding
  other parameters like acpi=force, noefi, fakebios.

  Even Xorg seems able to detect with nvidia proprietary driver the 2
  graphic cards, but he can't detect any monitor attached to them.

  I am attaching both dmesg and Xorg.0.log
