Comprei recentemente uma Lenovo g505s, cujas especificações podem ser encontradas aqui .
Depois de instalar o Ubuntu 13.04, tentei instalar os drivers proprietários da ATI. Mas apenas meus gráficos integrados estão sendo detectados. Além disso, há uma marca d'água de hardware sem suporte da AMD na parte inferior direita da tela (não é um problema, desde que o sistema funcione).
Mesmo o comando lspci -v não detecta minha placa gráfica dedicada. Tentei verificar meu BIOS, mas não consigo encontrar nenhuma opção para alternar entre gráficos integrados e dedicados. Atualmente, a opção de gráficos no BIOS está configurada para gráficos comutáveis.
Por favor, ajude-me a ativar minha placa gráfica dedicada. Aqui está a saída de lspci -v: -
