Screens Stop Updating

[Anonymau5]

Do you know how to use blacklist files in /etc/modprobe.d? If so you can blacklist the i915 module, which will prevent the Intel graphics from working, thus effectively going nVidia only.

echo "blacklist i915" | sudo tee /etc/modprobe.d/i915.conf

sudo update-initramfs -u -k all

Then reboot.

Rebooted to a blank screen, had to drop to terminal and undo it.

That's weird. Did you remove all the Bumblebee related packages?

I purged Bumblebee and all of it's related packages, reinstalled the nVidia driver, then black listed the HD4000 driver. I would see the boot logo and presented with a blank login screen. The monitor would shut off from a lack of signal.
I did a little research into why it would do this. Apparently the output from the nVidia card is funneled through a virtual input (I believe is't a virtual HDMI in) on the HD4000. If the HD4000 isn't running, than the nVidia card cannot deliver what it has rendered.
