Especificações do meu notebook:
CPU: Intel Core i5 3230m
RAM: 4gb 1600mhz
I have 2 GPUs:
1st: Intel HD 4000
2nd: Nvidia GT 720m
Hoje, instalei o zangão e o driver Nvidia 331. A instalação foi bem sucedida, então o notebook começou sem tela preta. O problema é que o notebook não inicia programas com a Nvidia. E não reconhecerá as GPUs. Aqui está o que eu fiz:
sudo apt-get install nvidia-331 bumblebee linux-headers-generic
sudo gedit /etc/bumblebee/bumblebee.conf
Substituiu as palavras-chave correspondentes por esses valores:
Driver=nvidia
KernelDriver=nvidia-331
LibraryPath=/usr/lib/nvidia-331:/usr/lib32/nvidia-331
XorgModulePath=/usr/lib/nvidia-331/xorg,/usr/lib/xorg/modules
Salvar e sair
Eu então removi o driver 304
sudo jockey-text -d kmod:nvidia_304
Em seguida, reconfigure algumas coisas, executando isto e pressionando ok.
sudo pam-auth-update --force
Rebooted.
Então eu instalei o VirtualGL
link
sudo dpkg -i virtualgl_2.3.3_amd64.deb
Depois de executar o optirun, aqui está a saída:
