The laptop I'm using is an MSI GT683DX-847PT that comes with an NVIDIA GeForce GTX570M discrete GPU, and an Intel Core i7-2670QM CPU.
According to Intel's description of the Core i7-2670QM CPU, it has an HD Graphics 3000 integrated GPU.
The problem is that the Intel integrated graphics GPU doesn't come up in lspci nor in lshw, only the NVIDIA GPU shows up. Here is the output of both commands:
sudo lspci: http://pastebin.com/raw.php?i=9AZg8bJy
sudo lshw: http://pastebin.com/raw.php?i=6cAMFQsY
I was counting on having two GPU's to run CUDA programs on the discrete NVIDIA GPU, while X was handled by the integrated Intel GPU, to prevent kernel execution timeout.
Why doesn't the Intel HD Graphics 3000 GPU show up? Any tests I could make to verify the presence of an integrated GPU?
