blank screen while booting

[nnutter]

I did a clean install of 14.04, updated, dist-upgraded and then installed nvidia-current. When booting I get a black/blank screen. If I add nomodeset at boot then I get a purple box that fills up about 75% of my screen but is otherwise blank. If I wait a bit I can type in my encrytion password and then the machine will continue booting and once it gets to LightDM/X the screen works fine.

From the debug logs I saw it trying to load the i915 driver which seemed suspcious so I checked my (UEFI) BIOS and there was a feature called "IGPU Multi-Monitor" enabled that looks like it might keep the integrated graphics card active even when there is a PCI-E card in place. I disabled that and I now see graphics while booting (and importantly the password prompt for full drive encryption).

I am not closing this myself because it still seems like a problem that many people could experience and who may be unequipped to deal with it.

Status changed to 'Confirmed' because the bug affects multiple users.

I'm having the same problem using the nvidia-331.38-updates driver. I followed your workaround on the BIOS, but the problems is still there.
I see a purple border around one of my screens, and then it's just blank with a blinking cursor. I don't have encryption, so I just went straight into the log-in window.
Before installing the nvidia propietary drivers, the log-in screen was great, where I could see the Ubuntu log on all my screens.
