Bug#924711: nvidia-driver: does not recognize thunderbolt DP monitor

[TheArtificialAmateur]

Further investigation led me to find the issue and a solution(?). As it turns out both the Intel integrated graphics and NVIDIA discrete graphics were activated. The discrete card is tied to the output, so if the session was running through i915 then HDMI and thunderbolt would not work. I attempted to blacklist i915 drivers through GRUB2, but was unsuccessful. I found that I had to disable the integrated graphics from the BIOS for it to work. External monitors are now working, question is, why didn't the integrated graphics get blacklisted by the NVIDIA drivers?

Side note: I thought about using bumblebee for the hybrid graphics, but according to their wiki external monitors do not yet work on bumblebee and I would be in the same situation.
