You have to add i915.lvds_channels=2 i915.modeset=1 i915.lvds_use_ssc=0 to the end of linux line, to prevent distorted screen, when X comes up. Now you can edit the /boot/grub/grub.cfg and simply add the following line to each of your grub boot menus that you need:ДЇor example here I added it to ubuntu boot menu: You can find using : ls -al /dev/disk/by-uuid/*ДЄnd choose the one that points to the partition containing the distroвЂ™s /boot folder.

#funny, the downloaded patch needs a new line at the end of the patch echo '' >/tmp/grub_gmux.patch

Calling it in your efi grub boot menu, will turn off the nvidia graphic card. This patch simply adds a new module `apple_gmux` to the grub modules. You can download the patch from GRUB module to Turn Off Apple MacBook Pro10,1 Nvidia Graphic Card.

To take a look at the grub source code go here: grub.git.

The following instructions are mostly based on UEFI Booting.ДЇirst install prerequisites: sudo apt-get install bison libopts25 libselinux1-dev autogen m4 autoconf help2man libopts25-dev flex libfont-freetype-perl automake autotools-dev libfreetype6-dev texinfo make git gcc liblzma5 liblzma-devДownload GRUB mkdir ~/sources & cd ~/sources.

On the fat32 partition, create these folders: # /dev/sd? is the fat32 partition.

If you already have a Linux distro, you just need to create a fat32 partition. The other is your normal linux distro partition that contains /boot. NOTE: There are two boot partition, one is a fat32 formatted partition that is used by Apple EFI boot loader which should contain /EFI/BOOT/BOOTењ†4.EFI. NOTE: Through out this page I use /mnt/efi as the place where the EFI partition is mounted. My MacвЂ™s SSD Hard disk is toasted, and I not able to test this setup on the internal hard disk. When MacBook starts up, I have to press the вЂOPTION KeyвЂ™ to be able to select the partitions. NOTE: IвЂ™ve installed Ubuntu on a USB stick, and the fat32 partition is also on that stick. I used the same strategy, but adapted it to the new gmux driverвЂ™s way.

Because in newer MacBooks, Apple has changed the way apple_gmux driver works.ДЇor example Installing Debian Wheezy (7.0) on an Apple MacbookPro9,1 (15вЂі, June 2012). But it does not work on mid 2012 and later MacBooks. NOTE: There is a solution, for this same problem on MacBook Pro early 2012 and before. IвЂ™m counting on the communityвЂ™s help, to make it better. NOTE: This is still a work in progress, so be patient! Treat it as an alpha release.

No need to change any X.org config files, Or any other file for that matter.

In Ubuntu, system simply boots to X window on the i915 driver.

The Nouveau module or Nvidia one, Dose not even load.

I think turning off the Nvidia Card during the boot time is much more elegant!.

Using direct access to the apple_gmux ports, you can change the cards, but then a black screen greets you, which you can do nothing! (maybe you need to restart X).

The Switcheroo interface, is not able to switch the graphic cards.

There are problems with X, which I could not solve them.

Switching the graphics cards after the system is booted, is not feasible.

It needs a lot less juice, giving MacBook a longer run on battery.

In contrast to Nouveau, the Intel provided Linux graphics driver is very fast and cool.

The Nouveau driver is not fast and reliable, it makes the hardware very hot and also drains the battery very fast.

So Switching the graphic cards using BumbleBee or NVIDIA prime is not possible on a Mac, until, NVIDIA CORP decides to make a better Linux driver.

One of the bugs in the Linux Nvidia driver by NVIDIA Corp, prevents the X from coming up, when system boots using EFI mode on a MacBook.

On the MacBook, only when the system boots using EFI, it has access to the onboard Intel graphic card.

To resolve this problem look at this comment.

Apparently, When Linux wakes up, the discrete graphic card turns on again.

Apparently, echo statement after apple_gmux in the boot menu hangs the boot! see this comment.

a small fat32 partition or if there is one, you can use that partition.
