Does Ubuntu12.04 Nouveau driver implement Optimus laptop
Hi Gud day,

I would like to ask about if someone out here use an optimus technology laptop install the bumblebee package to enable to use the nvidia graphics card.

I just wondering on my optimus laptop which i install the latest ubuntu dist. which is 12.04 precise and update to kernel as of this date is 3.2.0-24.
Im using lucyd and bumblebee to access my paid graphics nvidia card. Before no bumblebee package install i can't use google-earth
or so called webgl on a browser. In my understanding the intel card can't handle high end application that required a high end card which is the purpose of the
nvidia. with bumblebee installed google-earth and webgl is a piece of cake. an any application that required extensive graphics. Now im confused since the default
installation of the precise 12.04 as of 2012-06-01, the google earth and webgl works fine, so does it mean the default install driver can used the nvidia or access the nvidia card.
Question:

1. I never found nvidia module/driver loaded when i run google-earth not like the bumblebee "optirun <apps>" so therefore what driver is the apps using?
2. Does the nouveau driver can access or used the nvidia card ( nouveau driver is opensource driver for nvidia right )
3. On the nouveau official website, its states that Optirun technology is not implemented yet. then maybe im wrong thinking nouveau driver is using the nvidia card?

Thanks And Best Regards.

gvid_no_claim_dev

gvid_no_claim_dev(5)						File Formats Manual					      gvid_no_claim_dev(5)

NAME

       gvid_no_claim_dev - PCI Vendor/Device ID that the gvid graphics driver will not claim

VALUES

   Failsafe
   Default
   Allowed values
   Recommended values
       Specific to the device you wish to prevent from claiming.

DESCRIPTION

       This tunable specifies the PCI Vendor ID and/or Device ID of a graphics device that the HP graphics driver should not claim.

       The  graphics driver was designed to be a general purpose driver for all PCI graphics cards.  As a result, the driver will attempt to claim
       any PCI graphics display device found on the system.  This can be a problem for graphics device developers  who	need  their  own  graphics
       driver to claim their own graphics device.

       The  value  of will specify a PCI Vendor ID and/or Device ID of a graphics card that the gvid graphics driver should not claim.	It is a 32
       bit number, with the upper 16 bits containing the PCI Vendor ID and the lower 16 bits containing the PCI Device ID.  Either the	Vendor	ID
       or Device ID can use a wildcard value of

       For  example,  if  is  set to the value the driver will ignore graphics devices with a PCI Vendor ID of and a Device ID of If is set to the
       driver will not claim any graphics cards with a Vendor ID of regardless of the Device ID.

   Who Is Expected to Change This Tunable?
       Anyone who wishes the graphics driver to ignore a specific graphics device.  This will typically be  someone  writing  their  own  graphics
       driver for their own hardware.

   Restrictions on Changing
       Changes to this tunable take effect at the next reboot.

   What Other Tunables Should Be Changed at the Same Time?
       None.
