I recently purchased a Lenovo Y510p laptop. The laptop has an NVIDIA GeForce GT750M graphics card. Supposedly the laptop doesn't have integrated graphics but after installing Ubuntu 13.04 and installing the NVIDIA drivers I've discovered that my system is using the integrated graphics instead of the NVIDIA card and no matter what I do I can't seem to get the NVIDIA card activated. I've Googled the heck out of the issue with no success. Anyone have any ideas?
