I am completely new to Linux as of about two days ago, and ever since I installed it, I have been trying to get Steam to run games using my nVidia GPU with/instead of my integrated processor. I've been having issues with this even after installing Bumblebee. When I get my GPU information using lspci | grep VGA, it tells me I'm running a GeForce GT 540m instead of my GeForce GT 525m. I'm wondering if this is just a problem with what it says I'm running or if it means that the nVidia drivers I just installed were the ones for the 540m.

All I've done since I re-installed Ubuntu for the thousandth time is updated via the Software Center, installed Chrome and Steam, and updated nVidia drivers via sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-current nvidia-settings.

I'm using a Dell XPS L511z and using Ubuntu 12.04 LTS.
