Eu tenho o Bumblebee trabalhando. Estou usando o Mint 13 Mate de 64 bits, que é bem próximo do Ubuntu 12.04, no laptop Samsung Series 7 Chronos NP700z5c Optimus, usando a GPU Intel Ivy Bridge hd4000 Intel e a GPU Geforce gt 630m e a CPU i7-3615QM.
Este site ajudou muito: http://www.noobslab.com/2012/06/nvidia-drivers-collection-for.html
Execute todas as etapas aqui, exceto a etapa 7, e você deverá fazer o seguinte em um terminal:
sudo gedit /etc/modprobe.d/blacklist.conf
Agora adicione as seguintes linhas ao final do arquivo e salve:
blacklist amd76x_edac
blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv
Você precisará fazer o seguinte em um terminal:
sudo gedit /etc/bumblebee/bumblebee.conf
Altere-os no arquivo e salve:
Driver="empty or whatever" to Driver=nvidia
kernelDriver=nvidia-current to KernelDriver=nvidia
sudo update-initramfs -u
Inicializado pode ser um tipo de buggy teve que Ctrl+ Alt+ F6e então Ctrl+ Alt+F8 para sair da tela preta de pânico do Mint 13.
O Ubuntu usa teclas diferentes Ctrl+ Alt+ F1e depois Ctrl+ Alt+ F7.
sudo reboot
Em seguida, execute seu gerenciador de atualizações. Meu zangão não funcionou até o SO lançar as novidades.
Experimentar optirun glxgears em um terminal.

Eu corri:

optirun glxgears, and optirun glxspheres.
