nvidia driver

bumblebee will manage both gpus, you don't have to (actually you shouldn't) install any other driver, if you do it will mess things badly.

what bumblebee does (trying to explain in a simple way) is give you 3D by default using the intel card, if you need to use intensive gpu application you use the command

Code: Select all

optirun <appname>

Have you tried to download the Video Driver from NVIDIA and then install it from the CLI and updating your Xorg file?

I have nvidia 650MT... should I neglect this statement on the Bumblebee post you provided?


For more up-to-date nvidia drivers, you need to add another PPA. As of 12.04, this is still necessary for Nvidia GT 6xxM cards. It may be optional for the GT 4xxM and GT 5xxM series on 12.04. When in doubt, just install it. The command is:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

with nadia (quantal) your card is already supported (at least has drivers that minimally support it - this is the problem with state-of-the-art hardware: linux has to catch-up on it and there's a gap of non-support for some weeks/months)
from what i read online bumblebee as-is should work; the additional ppa is "only" to give you "more up-to-date drivers", but both ways should work

bumblebee worked. I have great performance.

1) Chrome://gpu : great

i'm glad to see that it's working
