Eu tive um problema semelhante, mas em vez de preto, minha tela estava roxa. Eu atualizei de 11.04 para 12.04 e a atualização ocorreu sem problemas (sem erros / sem avisos). Após a atualização e reinicialização, o X-server não respondeu. Nenhum mouse / nenhum teclado. ctl-alt-Fx não funcionou o teclado foi totalmente morto, caps-lock não alternou o LED, mas eu poderia ssh de outra máquina. Eu suspeitava que poderia ser meu driver gráfico não padrão da ATI. Depois de muita pesquisa, encontrei um novo instalador AT, mas tive que desinstalar o antigo primeiro.
- Transferiu o mais recente instalador da AMD do link
- Desinstalado o antigo driver fglrx por
sudo apt-get remove fglrx -
sudo ./amd-driver-installer-12-6-x86.x86_64.run
Após o passo 2 eu pude reiniciar meu PC e as coisas estavam melhores. O mouse se moveu e eu pude digitar. Então eu tentei instalar o driver AMD ATI mais recente e depois de uma reinicialização funcionou.
