Olá, tenho um Notebook HP G42-371BR que veio com Windows 7 Home Basic. Estou usando nele o Ubuntu 13.10 (Saucy Salamander) 64 Bits. Ele tem duas placas de vídeo (integrada e discreta). Quando inicio o sistema ele usa a integrada, e eu gostaria de ativar a discreta para os jogos. Pesquisei na internet e descobrir o vgaswitcheroo. O meu problema é o seguinte, quando executo os comandos para ativar a discreta e depois o comando: gnome-session-quit --logout --force, para finalizar a sessão. Ele finaliza a sessão mas não volta, fica em uma tela preta com o computador travado. O que devo fazer para resolver isso?
