Hi guys in this video i will be showing how to Use your macbook pro with defekt AMD Radeon GPU using the Intel HD Graphics and Ubuntu OS. I think throw to the garbage a Macbook Pro is not the solution, so after lot of research i came with this Solution, Ubuntu runs awesome as well all the drivers and Functions of the Macbook.
Take a look here to the Steps as well follow the video for detailed steps:

Steps:

1.  Download Ubuntu Desktop .iso from the official Ubundo Website

3.  Turn On the Macbook Pro, press ALT key to get into Boot Options
4.  Select USB with Ubuntu
5.  press "e" when Try Ubuntu is selected to go into the Linux Boot Kernel

after  "load video"

 outb 0x728 1
 outb 0x710 2
 outb 0x740 2
 outb 0x750 0

after "quiet splash"

 i915.lvds_channel_mode=2 i915.modeset=1 i915.lvds_use_ssc=0

6.  Press F10 to boot into Try Ubuntu
7.  Follow the installation procedure of Ubuntu Manager
8.  When is finished, restart the Macbook and press ESC key one time when the ring bell sound
9.  Press "e" when Ubuntu is selected and modify the Kernel again like in the Video
after  "load video"

 outb 0x728 1
 outb 0x710 2
 outb 0x740 2
 outb 0x750 0

after "quiet splash"

 i915.lvds_channel_mode=2 i915.modeset=1 i915.lvds_use_ssc=0

10.  Open the Terminal and write the following

 sudo nano /etc/default/grub

replace the text GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash“
 with = GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash i915.lvds_channel_mode=2 i915.modeset=1 i915.lvds_use_ssc=0"

 save the text with ctrl+x and Yes and hit Enter to save

11. Write the following and open
 sudo nano /etc/grub.d/10_linux

 press Ctrl+w to find the word "gzio"
 insert the next commands before the line of "gzio"

echo "    outb 0x728 1" | sed "s/^/$submenu_indentation/"
echo "    outb 0x710 2" | sed "s/^/$submenu_indentation/"
echo "    outb 0x740 2" | sed "s/^/$submenu_indentation/"
echo "    outb 0x750 0" | sed "s/^/$submenu_indentation/"
echo "    insmod gzio" | sed "s/^/$submenu_indentation/"

12.  save the text with ctrl+x and Yes and hit Enter to save

Follow the video....
13.  sudo update-grub
14.  sudo apt-get update  
15.  sudo apt-get upgrade
16.  Restart the Macbook

Step number "8" is not working. "When is finished, restart the Macbook and press ESC key one time when the ring bell sound" ESC is not working after restart from installation of Ubuntu 21.04.
