When installing Ubuntu, I opted for the minimal install (for the minimal install time running on this wonky GPU), but I did choose to install proprietary drivers (this is required for Wi-Fi to work). I found it helpful to also utilise this GitHub project to disable my dGPU within the UEFI at boot. Instead I just proceeded to boot, as my GPU still partially works for incredibly short periods of time. I found many guides telling me to enter the grub menu, but unless you’ve already got a working rEFInd installation, you’re going to struggle. This is easier said than done but when booting the Mac, I first plugged in the USB and then I held down Alt, getting the boot options.

Rufus has an awesome FAQ section that can answer any questions with using the tool. I then proceeded to use the handy tool Rufus to image my USB drive with this. I went to the Ubuntu website and downloaded the latest Ubuntu 20.04 LTS ISO. With that in mind, let’s now work to circumvent the dGPU! Step One: Prepping the Live CD Apple did launch a repair program however they merely swapped the logic boards with identical ones, meaning the problem was only delayed, never resolved. Why does the GPU fail? Macrumours did a write up discussing this in more detail, especially in relation to the repair program but in essence, the AMD GPUs have design defects, and over time & use, causes them to fail at a much faster rate than other GPUs on the market. This will help extend the life of our MacBook Pro by preventing the AMD GPU being powered on for longer than the boot sequence, and therefore prolong the time until failure.

We can exploit this by forcing the gmux chip to only use the iGPU and even tell it to power down the dGPU. This chip allows for the operating system to tell the gmux chip which GPU is required for the workload, iGPU for best battery life, or dGPU for performance. These are both wired to the screen via a chip commonly referred to as the gmux chip.

Prerequisitesġx Machine capable of creating a Live CD onto your USB of Ubuntu Overview:ĭid you know that the 2011 MacBook Pro has two graphics cards, the dedicated GPU (dGPU) and the integrated GPU (iGPU). Want more consumer news? Visit our parent organization, Consumer Reports, for the latest on scams, recalls, and other consumer issues.This is just a personal note of what I did to get my Macbook Pro Late 2011 with failed/failing AMD GPU to boot Ubuntu 20.04 LTS, hopefully it helps someone. MacBook Pro Repair Extension Program for Video Issues Users are only to bring in their computer if it has a graphics failure: bringing it in before anything goes wrong, or for any issue that doesn’t involve the graphics, won’t be covered by this repair program. Here are the models that Apple will cover as part of the official repair program, which were sold from 2011 to 2013. The graphics issue involves a failure of machines’ discrete graphics card, which is only used when performing graphics-intensive tasks like watching or editing videos. The repair program begins today, and extends repair coverage for affected MacBook Pro models for this specific issue only. Apple has now announced a repair program in response to users’ complaints, and perhaps also in response to their class action lawsuit. These pink and white stripes are not pretty.Back in October, we shared some MacBook Pro owners’ complaints about their computers, which had what can broadly be described as “video problems” that often rendered the computers unusable.
