This is my current system configuration. I use the intel graphics for graphics, and just keep the NVidia card running for CUDA applications. Note that this setup does not give you 3D acceleration on the NVidia card!

Sometimes (only after suspend) I have to use the attached reload_nvidia.sh script because my CUDA applications complain about a "invalid device ordinal".

BIOS version: 1.17
Linux: Ubuntu 14.04 with kernel 3.17.0-031700rc4-generic
kernel cmdline: "acpi_osi=!Windows 2012"

nvidia driver 340 manually installed from the xorg-edgers PPA:

This was tested on a ThinkPad P70 laptop with an Intel integrated graphics and an NVIDIA GPU:

lspci | egrep 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GM204GLM [Quadro M3000M] (rev a1)

A reason to use the integrated graphics for display is if installing the NVIDIA drivers causes the display to stop working properly. In my case, Ubuntu would get stuck in a login loop after installing the NVIDIA drivers. This happened regardless if I installed the drivers from the "Additional Drivers" tab in "System Settings" or the ppa:graphics-drivers/ppa in the command-line.
