-====== Ubuntu - GPU - AMD GPU - Enable AMDGPU Linux Driver ======
-<WRAP info>
-**NOTE:**  This is not required for the newer **amdgpu**, but might be helpful for older systems.
-</WRAP>
-To enable **amdgpu** special kernel boot parameters should be set.
-The easiest way is to make it permanent and apply it to all kernels (no messing around with grub.cfg), will be:
-  * Edit the defaults in **/etc/default/grub** by changing the **GRUB_CMDLINE_LINUX_DEFAULT** parameter.
-  * Update GRUB, by running **update-grub**.
-----
-===== Requirements =====
-  * A newer Linux kernel.

-===== Check to see if amdgpu is enabled =====

-===== Edit the defaults for GRUB =====
-Edit **/etc/default/grub**.
-Modify the **GRUB_CMDLINE_LINUX_DEFAULT** line to:

-=====  Remove old radeon.conf files =====
-Old **radeon.conf** files should be removed as they may stop Xorg from starting.
-<code bash>
-sudo mv /usr/share/X11/xorg.conf.d/20-radeon.conf ~/

-=====  Add a new amdgpu config file =====
-Create a **amdgpu.conf** file, if it does not exist.
-<code bash>
-sudo vi /usr/share/X11/xorg.conf.d/10-amdgpu.conf
