Hey guys, I'm super super new to linux, but I'm really excited to learn. I just bought a Dell XPS 15 (Sandybridge i7 with Nvidia 525M) and while troubleshooting the video issues I was having, I learned about this project.
I'd really love it if someone could point me in the right direction as far as; 1. Installing the Intel onboard HD drivers 2. Installing the *right* nvidia driver and disabling it (turning it on kills the GUI) 3. Installing the correct switcheroo package. Thanks in advance!
