Monitor não funciona com Ubuntu 13.04

[Robs]

Instalei o ubuntu 13.04 no meu Notbook, mas quando eu ligo,  depois do sistema iniciar a tela fica preta! Se eu ligo com o cabo HDMI na tv ele funciona normal (mas só na TV)

Seu monitor funciona normalmente em outro sistema operacional?

Sim, funciona normalmente no Windows 7 e 8

[Arthur Bernardes]

Tente entrar nas configurações de monitor, e deixar os dois ligados. A sua TV deve estar sendo a principal e desligando o vídeo do seu note.

O comando lspci teria sido mais conciso, demorei um pouco para perceber que você tem duas placas de vídeo aí, uma Radeon HD 6400M da ATI e outra onboard da Intel (é isso mesmo?). Você instalou algum driver proprietário da ATI/AMD?

[Robs]

Instalei os drivers e não mudou nada 


Achei um site falando sobre este problema:http://www.diolinux.com.br/2013/01/tela-escura-no-notebook-hp-pavilion-como-resolver-este-problema.html

Vou testar e depois posto aqui se deu certo ou não

[Arthur Bernardes]

Lembrando Sergio, que o sudo lshw -C video exibe com precisão informações sobre o vídeo de um computador.

[Robs]

Deu certo!
