bbswitch problema no Ubuntu 13.04!

Question

Eu tenho um laptop Sager np8290 com NVIDIA geforce GTX 770m (optimus). Atualmente estou tentando obter bumblebee para trabalhar com o Ubuntu 13.04. Através de toda a bagunça, e novas instalações do sistema, eu pude fazer o bumblebee funcionar, eu acredito, porque eu posso rodar o glxspheres do optirun e ele funciona bem. Eu não posso executar bbswitc h embora. Eu sei que a placa principal da Nvidia está funcionando constantemente porque o computador está ficando muito quente e a ventoinha continua acelerando.

Executando sudo modprobe bbswitch dá

ERROR: could not insert 'bbswitch': No such device

E a execução de bumblebeed -vv dá

Estou executando o kernel atualizado agora

$ uname -r
3.9.4-030904-generic

Não tenho outra ideia de porque não consigo executar bbswitch . Eu gostaria de desligar a placa Nvidia para evitar que fique tão quente!

Todas as ideias ou links para outras soluções seriam bem-vindas.

    

Answer 1

Bem, você não está sozinho pelo menos.

MSI GE40 aqui, com a GTX 760M. Exatamente os mesmos problemas, optirun funciona bem e faz a diferença, mas não consigo desligar o cartão discreto (e ele está usando a maior parte da energia). Não / proc / acpi / bbswitch - bbswitch não gosta de carregar:

[119624.055053] bbswitch: version 0.7
[119624.055059] bbswitch: Found integrated VGA device 0000:00:02.0: \_SB_.PCI0.GFX0
[119624.055062] bbswitch: cannot find ACPI handle for VGA device 0000:01:00.0
[119624.055064] bbswitch: No discrete VGA device found

Se eu encontrar uma solução, voltarei aqui ...

Editar: encontrei este tópico,

link

que nos diz que é um bug do kernel do kernel 3.8.5-1. Espero que haja um lançamento do kernel funcionando novamente em breve. Leia esse tópico se você quiser compilar seu próprio kernel ou voltar o kernel para o 3.8.4.

    

Answer 2

Eu tive o mesmo problema. Estava usando o Ubuntu 12.04 LTS com o kernel 3.8.0-31-genérico (kernel do Ubuntu 13.04). Consegui obter optirun e primusrun para ambos funcionarem, mas o bbswitch não desligará o GPU discreto automaticamente após o uso.

Eu consegui fazer o bbswitch funcionar no final, instalando o kernel v3.11 mais recente. Seguimos os passos nesta página: link
