I'm having a laptop with
nvidia 520mx graphics card with
nvidia optimus technology running Ubuntu 14.04. I've installed nvidia graphics driver version
nvidia-prime. What I want to do is to switch the Intel graphics card with Nvidia. Running Nvidia X server setting is not showing me any option to switch between two graphics card.
Below images show which driver I'm using and what am I missing.
Why the option to change graphics card is not present in Nvidia X server setting in my case ? Any help is appreciated.
