Eu segui estas instruções para instalar o driver nvidia no debian buster link
Eu rodei nvidia-settings e ele disse que eu preciso rodar o nvidia-xconfig para usar o driver.
Depois de executar o nvidia-xconfig, o lightdm se recusa a iniciar.
Esta é a saída relevante da execução de journalctl -u lightdm (Ignore o fato de que meu sistema tem o nome "shitfaced". Ou não, qualquer que seja ...)
