Olá, boa noite!
Meu nome é Thiago, possuo um Notebook Dell Inspirion 15R Special Edition, com as seguintes configurações:
Intel Core i5 3210m com clock de 2.5ghz a 3.1ghz, com Placa de Vídeo HD 4000 (integrada);
Placa de Vídeo Dedidcada AMD HD 7730M;
6GB de Memória RAM DDR 1.333;
HD 750GB 7200RPM;
Sistema Operacional Ubuntu 15.04 64 Bits com Kernel 3.19 e todas as atualizações feitas.
Meu problema:
O Ubuntu reconhece a existência das duas placas de vídeos, porém eu só consigo utilizar a placa de vídeo integrada da Intel (HD 4000).
Já tentei de tudo pra "ligar" e usar a placa dedicada (AMD HD 7730M), porém não consigo.
Obs.: Estou querendo usar os drivers opensources mesmo, pois me servem melhor para o uso geral no Desktop e pelo que tenho pesquisado eles já têm um bom desempenho para os jogos que jogo (atualmente Dota 2 da Valve).
Aí vão alguns comandos pelo terminal que podem ajudar:

Eu não me importo de desligar a placa intel, pela questão de autonomia da bateria, até porque utilizo o notebook tal qual um desktop, praticamente não tiro da tomada.
Qualquer ajuda é bem vinda, desde já agradeço.
