As workaround it is possible to manually install the firmware to get a navi GPU (Radeon RX 5300, 5500, 5600, 5700) to work by doing this: sudo apt install git git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git cd linux-firmware/ sudo cp -va amdgpu/ /lib/firmware/ sudo update-initramfs -u reboot
