I have an Acer Aspire 5935G. It comes with hybrid grahics solution from Nvidia. It has two graphic cards; Nvidia GeForce 130GT M (discrete) and Intel mobile graphics series 4. I have just installed Ubuntu 11.10 but I get no information about what graphics card the notebook is currently using. Also how can I use only one of them permanently (preferably Intel graphics), while disabling the other?
Tell me more

By default optimus is not supported in ubuntu so you are probably using your intel card if you havent installed bumblebee. if you want to use optimus you can use the bubble bee projects to run particular programs through the nicer nvidia GPU. it uses a virtual framebuffer to reroute the whole thing. Pretty tricky stuff but relatively transparent to the end user. |

lspci | grep VGAfrom your terminal? Also did you check this question - I have a hardware detection problem. What logs do I need to look into?? – nitstorm Feb 23 '12 at 15:08
