alguns dias atrás eu tentei instalar o Ubuntu 18.04 no meu computador Notebook. Mas o processo de instalação congela na frase inicial. Então alguém me sugere para adicionar nomodeset no grub. Depois de adicionar nomodeset no grub. Ubuntu instalado com sucesso. mas depois do login eu vejo que o desktop Ubuntu está rodando em gráficos baixos. Alguns poss diz que eu tive que instalar drivers NVIDIA (como notebok tem placa NVIDIA Geforce 520M). Eu segui suas instruções, mas ele trava o sistema operacional.
