Eu tenho um Acer Aspire 5 A515-46-R3UB, AMD Ryzen 3 3350U, 4GB DDR4, 128GB NVMe SSD, WiFi 6. ele veio com windows 11 e usei ventoy kubuntu 20.10 iso e ao atualizá-lo retornou os erros abaixo. depois de várias tentativas e falhas, finalmente resolvi os erros do terminal. minha solução foi a seguinte.
sudo apt install git
cd ~/Documents && git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp ~/Documents/linux-firmware/amdgpu/* /lib/firmware/amdgpu && sudo update-initramfs -k all -u -v
sudo apt update && sudo apt upgrade
reboot
embora os erros não sejam mais retornados, minha tela agora fica confusa quando abro a tampa apenas por um breve segundo antes de voltar ao normal. não está danificado porque instalei o Windows 10 para ver se o problema estava presente no sistema operacional Windows e funcionou normalmente. então reinstalei o Kubuntu e resolvi novamente o problema de firmware ausente, mas a tela ainda pisca confusa ao ser aberta, independentemente de estar no estado de suspensão ou apenas fechada e reaberta. imagino que seja um bug de renderização com o firmware da GPU. Alguma ideia?
