I have a Sony Vaio laptop with an i5 460M CPU and a NVIDIA 310M graphics card. There was no mention by Sony about support for hybrid graphics (specifically Nvidia Optimus), but the processor does have integrated graphics, according to the Intel web site.
However, in the output of
lspci -v | grep VGA there is only the entry for the Nvidia dedicated card:
01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 310M] (rev a2) (prog-if 00 [VGA controller])
On the other hand, Ubuntu seems to be trying to load some Intel/Graphics related modules, since I get the
failed to get i915 symbols, graphics turbo disabled error during boot.
Therefore, I'd like to know if there is the possibility of using the Intel graphics, with bumblebee, or is it safe to remove the modules from boot (it slows down boot for a few seconds).
Any help will be appreciated!
