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.

lm-profiler

LM-PROFILER(8)						      System Manager's Manual						    LM-PROFILER(8)

NAME

       /usr/sbin/lm-profiler - laptop mode profiler

SYNOPSIS

       /usr/sbin/lm-profiler

DESCRIPTION

       This  manual page documents briefly the /usr/sbin/lm-profiler command. lm-profiler is a tool for profiling disk operations. It is a part of
       laptop mode tools and is useful only in relation to rest of laptop mode tools. It helps you to detect programs and  services  that  use	up
       system resources and that cause disk activity, and it allows you to disable them when laptop mode is active.

       When  you start lm-profiler, it will execute a "profiling run", which can take some time. Start lm-profiler when you are working on batter-
       ies, preferably, because that will allow it to analyze the actual situation that it is supposed to optimize. During the profiling run,  you
       can  use  your system normally; however, any disk activity caused by your actions will end up in the profiler's results. When the profiling
       run is finished, you will be presented with a list of programs that deserve your attention, either because they listen on a network  (which
       is  not	usually  useful when you are working offline) or because they caused disk activity in a disk-spindown-unfriendly pattern. When lm-
       profiler can guess an init script that belongs to a program, it presents you with the opportunity to disable the program when you are work-
       ing  on battery. It does this by placing a link to the init script in /etc/laptop-mode/batt-stop. Any programs that lm-profiler cannot find
       an init script for is simply reported, so that you can stop the program manually if you want to.

       WARNING ABOUT DISABLING PROGRAMS: It may not be safe to disable some programs. They may be needed for proper operation of your system. Dis-
       able services only if you know what they do and why you don't need them.

FILES

       /etc/lm-profiler.conf
	      lm-profiler retrieves its profiling rules from this file.
