It’s possible that some graphics hardware could have different options here, or that future drivers could change the options. You can select “Custom Settings” if you’d rather tweak those settings yourself. Set General Settings to “Performance.” This chooses the best-performing settings for anisotropic filtering and vertical sync.This particular option is a good halfway point between disabling anti-aliasing entirely and using the slower MSAA approach. That way, if a game requests MSAA anti-aliasing, the Intel graphics driver will use a better-performing alternative instead. If you choose “Use Application Settings” for Set Multi-Sample Anti-Aliasing, despite our recommendation, set Conservative Morphological Anti-Aliasing to Override. Set Conservative Morphological Anti-Aliasing to “Override Application Settings.” This is an alternative to the above setting.This boosts your performance at the cost of some jagged edges. Set Multi-Sample Anti-Aliasing to “Turn Off.” Even if applications request multi-sample anti-aliasing to reduce jagged edges, this option makes the Intel graphics driver ignore that request.Set Application Optimal Mode to “Enable.” This option enables optimizations that increase performance in a variety of games.It just somehow screws up displays on the Intel graphics. The driver is actually working, as I can execute my CUDA job and use nvidia-smi from the TTYs. Xauthority file has the correct permission, and removing it does not resolve the issue.

xsession-errors reports extension 'GLX' missing on display ':0' after the failed logins. I just want them to function like two separate independent graphics cards, like they would do on Windows. I don't want to switch between the two graphics cards.

I checked out Bumblebee, which doesn't seem related to my use case. The NVIDIA driver seems to be interfering with my integrated graphics card and I end up with a login loop if I select my integrated graphics as the POST display. I can set this up pretty easily with an AMD card because it doesn't require additional drivers. I want to use the NVIDIA card for some CUDA computation and the integrated graphics to drive a monitor. I had no problems until I switched on the iGPU (Intel HD Graphics 4600) in the UEFI settings. I'm running Ubuntu 14.04 on a system with an NVIDIA Geforce GTX 950 graphics card.
