Responding to Ryan’s potential issue with a Vega GPU in the latest DL, this may also be helpful for others…

If you can’t start your Linux desktop environment you might be missing microcode (ucode). freedesktop.org is a good source for FOSS Radeon ucode among other things, their collection is here: https://people.freedesktop.org/~agd5f/radeon_ucode/

Installation guide:

# Go to: https://people.freedesktop.org/~agd5f/radeon_ucode/ and note the folder name of the ucode you want.

# Boot to terminal (recovery mode)

# Get the latest kernel
sudo apt update && dist-upgrade

# Download the ucode (replace FOLDER_NAME with the one you want)
wget -m -np https://people.freedesktop.org/~agd5f/radeon_ucode/FOLDER_NAME/

# Move the ucode to the right location
sudo mkdir /lib/firmware/amdgpu
sudo cp ./people.freedesktop.org/~agd5f/radeon_ucode/FOLDER_NAME/*.bin /lib/firmware/amdgpu

# Add it to your existing kernels (you'll need to do this whenever you update to a new you kernel)
sudo /usr/sbin/update-initramfs -u -k all
sudo reboot
