Hi,

I had a asus u30jc laptop with dual video NVIDIA OPTIMUS features (Built-in Intel and Nvidia geforce 310M), I just wondering if someone already figure out how the official nvidia driver works, or any tweaks inorder to use the nvidia card, Ive been using this laptop for more than a year now, and i cant figure out or find a tutorials that work (when i try installed any nvidia driver it render a black screen when boot-up, no success in xorg tweaks)..Correct me if im wrong, Basically if no nvidia driver installed on my laptop then my system will resort to use the nouveau driver right, so my question would be,"1.) what video card(Intel or Nvidia) is the system using? 2.) If no nvidia driver installed my geforce 310M cuda is useless right?"

Upon researching this nvidia optimus technology i stumble "Bumblebee" it suppose to switch you between intel and nvidia based on application you want to run.
Does anyone using this Bumblebee and notice some HW effects on application using it, i tried it and see no difference from running in normal and using bumblebee "optirun <application>"

Did you try it this way...

If I assume that you are using Ubuntu, you can use the Bumblebee repository, otherwise compile from source. This is the latest version of Bumblebee.

If you want to see which graphics chip is in use, try the command "lsmod" and look for Intel or Nvidia or the command "dmesg | grep intel" or grep | nvidia.

@ thorkelljarl: Thanks very much.

Ive solve temporary my objective which is " How to used my nvidia card in my laptop with optimus technology switching" I found this on the internet bumblebee and ironhide application, basically a program in which it will enable us to use our nvidia card on certain application i desired, I've tried bumblebee but not ironhide. the clue for solving optimus technology would be "bumblebee & ironhide" so its up to you to search and read in the internet,

Some referrence:
BumbleBee(support ubuntu. arch) and Ironhide (only ubuntu) are thesame

The latest...

Ironhide has not continued development, but Bumblebee 3.0 has taken over. It does make Optimus work, and without it, unless you can switch between Intel and Nvidia in your BIOS, you will be limited to using only the Intel chip and not the Nvidia you paid for.

@thorkelljarl: Thanks,

I just confirm right now that my nvidia is working by running google-earth in which some months back dis-appointed as why my google earth won't run and throw more errors.

Im satisfied with bumblebee right now, it works, google-earth a demanding apps for display is working right now..yahoo...thanks...bumblebee...
