#  Radeon 6000 series Graphics on Linux Mint

## Note:  ensure nomodeset is not in your Grub config.  Check/modify via `sudo bash -c "xed admin:///etc/default/grub"`.
## Note2: May have issues with games starting or saving to the cloud, such as Death Stranding.  If that's the case, delete the data install.  For example, for Death Stranding, execute "rm -rf ~/.steam/debian-installation/steamapps/compatdata/1190460"
## Todo: Need to -> purge amdgpu* as pre-caution?

sudo bash -c "add-apt-repository --remove ppa:oibaf/graphics-drivers" # just in case this is here, get rid of it
sudo bash -c "add-apt-repository ppa:kisak/kisak-mesa"
sudo bash -c "apt update && apt upgrade"

wget https://repo.radeon.com/amdgpu-install/21.40.1/ubuntu/focal/amdgpu-install_21.40.1.40501-1_all.deb -O amdgpu.deb
sudo bash -c "dpkg -i amdgpu.deb"

## The above should be all you need.  Verify:
inxi -XG  # output should contain "driver: amdgpu"

## If the above expected output wasn't the case, then run in terminal, `amdgpu-install`.  Should do lengthy install and generate module dependencies for installed kernels.
