1rst caveat - I am no expert, and do not use Intel video. I do believe that to use Nvidia drivers one has to explicitly install them. This is because the nouveau driver ships with the regular install, and is incompatible in that both cannot be used at the same time. When Nvidia drivers are installed, either via repo or the .run file from the Nvidia web site, the nouveau kernel module gets "blacklisted" to prevent it from loading at boot.
This is done by a file in /etc/modprobe.d and will contain a line with: 'blacklist nouveau' in it. Indeed, if you try to install using the .run file from the web site while in an init 5 desktop it will stop with an error that it cannot continue because it can't get rid of the running nouveau module and please go to an init 3 to install.
11.2/kernel-2.6.37-41-default NVidia 4300GS NVidia 260.19.36 nouveau module is loaded, not blacklisted. ...
When you install Nvidia drivers, along with them come an Nvidia version of the OpenGL libraries. These will only work with the Nvidia kernel module and Xorg driver combination; they will not work with anything else. If they were somehow accidently left behind after a failed attempt at removing Nvidia, you would find that OpenGL would no longer function when switching back to the Intel video.
