-====== Ubuntu - GPU - AMD GPU - Enable AMDGPU Linux Driver ======
-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 =====

-=====  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 ~/
