You may also need to run sudo dpkg-reconfigure nvidia-current after rebooting. (optional) If you don’t see the nvidia logo or get a blank screen, try installing gfxCardStatus (version 2.2.1, not 2.3), and forcing the discrete graphics card from the dropdown menu of their toolbar icon.Reboot and you should see the nvidia logo during boot /rebates/&252fdownload-gfxcardstatus-but-max-version-2-2-1.edit /etc/default/grub and add i915.lvds_channel_mode=2 i915.modeset=0 i915.lvds_use_ssc=0 to GRUB_CMDLINE_LINUX_DEFAULT inside the double-quotes between the words “quiet splash”.This is the only way to get the Intel card to work until vgaswitcheroo fixes this. This step is very important as it will allow you disable the NVIDIA card, allowing the Intel one to work. edit /etc/X11/nf and add to the Device section: Option "UseDPLib" "off" First, while using Mac OSX, download GfxCardStatus version 2.2.1 (not 2.1 or 2.3+, it need to be 2.2.1) and select integrated graphics.
GFXCARDSTATUS 2.2.1 INSTALL
sudo apt-get install linux-headers-$(uname -r).Now you’ll need to install the proprietary NVIDIA drivers, and configure Xorg: Note: After changing to EFI, you may get a blank screen for several seconds during boot-up. (optional) if you want to remove some of the extra rEFIt options, just delete the directories you don’t want from /boot/efi/EFI (be VERY CAREFUL here, and don’t delete the APPLE directory).You’ll probably have several new options in rEFIt, select any of them to boot up Make sure that “Separate /boot/efi partition” is checked, then click the “Apply” button, and follow the directions (you’ll be asked to remove and reinstall GRUB).Click on “Advanced options”, go to the “GRUB location” tab.sudo apt-get install -y boot-repair & boot-repair.
sudo add-apt-repository ppa:yannubuntu/boot-repair.Follow these steps adapted from the Ubuntu UEFI page (note: as of this writing the PPA is missing the packages for trusty, so you’ll need to use the saucy packages instead): To get the 2880x1800 native resolution, and the external display ports working you’ll need to convert GRUB to EFI mode.
GFXCARDSTATUS 2.2.1 UPDATE
Sudo apt-get update & sudo apt-get install bcmwl-kernel-source
GFXCARDSTATUS 2.2.1 DRIVER
Wifi doesn’t work out of the box, so from another computer (or your OSX install) download the driver and its dependencies (dkms, libc6-dev, linux-libc-dev), then copy them all to a flash drive and boot back into Ubuntu. UPDATE: OS X BSOD ‘Superbug’ gfxCardStatus 2.0 adrotate banner45 Following the discovery by DPS Computing that gfxCardStatus 2.2. Just press spacebar and it should reboot. Also, at the end of the installer, after the dialog asking you to restart, you’ll probably get a black screen. Note that the wifi won’t work (we’ll fix this in the next step), so don’t try to install updates during the installation process, unless you have a separate usb wifi dongle or ethernet. Make sure you download the 14.04 ISO though, for step 3. Just follow steps 1 through 3 in my first guide, to get rEFIt installed and prepare to install Ubuntu. Better nvidia support (no more need to set kernel options).It seems quite stable so far, and is mostly the same as 13.10 and 13.04. However, I did a fresh install of 14.04 on my macbook pro (rMBP).
I did an upgrade install of 13.10, so I skipped writing a blog post about it.
