Eu tenho um laptop Lenovo G510 e Ubuntu 14.04 LTS instalado nele e quando executo lspci | grep VGAele mostra apenas a placa gráfica integrada Intel, mas nenhuma informação sobre a placa AMD Radeon.
O que devo fazer? Já tentei vários tutoriais sobre instalação de drivers proprietários da AMD (fglrx etc.), mas não ajudou. O resultado foi 'modo gráfico baixo', então tive que desinstalar os pacotes fglrx.
Esta é a saída dolspcicomando:

Agora posso ver a placa AMD Radeon. É AMD Radeon R7 M265. lspci está mostrando a placa AMD porque mudei de UMA Graphics para Switch Graphics no BIOS. No entanto, não consigo instalar os drivers AMD para esta placa de vídeo. Após a reinicialização, o sistema operacional entra no modo gráfico baixo. O que posso fazer?
